Post-EOL Cybersecurity Validation for Automotive Production ECUs2026-26-06081/16/2026
ISO/SAE 21434 emphasizes comprehensive cybersecurity risk management throughout the automotive lifecycle. However, specific guidance on validating cybersecurity measures at the production level remains limited. This paper addresses the gap in production-stage validation, particularly after End-of-Line (EOL) flashing, which includes configurations of security hardware and software protection (e.g., UCB confirmation, JTAG, and P-flash password settings). Problem articulation: Current automotive cybersecurity validation methods, despite adherence to ISO/SAE 21434, lack specific procedures for the production stage. The existing system-level validation using the ASPICE V-model (e.g., SWE.6, SYS.5) does not ensure the integrity and functionality of cybersecurity features in the final manufactured unit post-EOL flashing. This gap poses a risk of vulnerabilities being introduced during the EOL process, compromising critical security measures. Proposed solution: To mitigate the cybersecurity

Transforming Gear Manufacturing_ A Deep Learning Approach to Quality Prediction2026-26-06461/16/2026
The automotive industry is rapidly transitioning towards Industry 4.0, transforming vehicle manufacturing. To achieve a lower carbon footprint, it is crucial to minimize raw material wastage and energy consumption. Reducing component wastage, lead time, and automating gear manufacturing are key areas. Gear micro-geometry inspection is vital, as variations affect service life and NVH (Noise, Vibration, Harshness). Despite standards for permissible errors, manual evaluation is often needed.This subjective evaluation approach will have a possibility that a gear with undesired variations gets assembled into the product. These issues can be detected during NVH testing, leading to replacement of part and re-assembly thus increasing lead time. This generates a need for an automated system which could reduce the human intervention and perform the activity. This paper discusses methodologies to meet these requirements and achieve desired results. The research aims to develop a deep learning

Balancing global and local formability properties through Nb microalloying2026-26-03031/16/2026
David Martin, CBMM Asia Bernardo Barile, CBMM Europe BV Caio Pisano, CBMM Europe BV Automotive high strength steels have specific microstructure-dependent forming characteristics. Global formability is generally associated with high uniform strain values which imply good drawability and stretch forming properties driven by pronounced work hardening. Local formability on the other hand is often measured by various fracture strain values—generally higher in single phase steels. In this respect, the so-called ‘local/global formability map’ concept has been established not only to provide a comprehensive methodology to characterize existing automotive steels but also to enable improvement strategies toward more balanced forming characteristics. Niobium (Nb) microalloying is a powerful tool to achieve both property improvement in general and property balance in particular.

A Novel Approach to Deep Drawing Using Hybrid System and Pneumatic-Assisted Forming2026-26-03011/16/2026
ABSTRACT: This paper presents a novel Plunger-Integrated Hybrid System aimed at enhancing the efficiency and performance of deep drawing operations in metal forming processes. The proposed hybrid system strategically combines the mechanical strength of metals with the elastic flexibility of polymers, specifically polyurethane rubber, to improve formability and reduce spring-back, two critical challenges in conventional sheet metal forming. A novel two-stage forming technique is employed, an initial drawing operation using a larger radius with polyurethane rubber, followed by final radius formation using the same rubber in conjunction with a pneumatic cylinder. This integrated approach ensures uniform force distribution via the embedded plunger, significantly minimizing forming defects and enhancing the dimensional accuracy of the final components. The solution has been validated using Finite Element (FE) simulation methods, confirming its capability to produce high-quality parts

Effect of the Flow Forming Process on the Mechanical properties and Microstructure of GDC & LPDC cast aluminum alloy wheels.2026-26-02981/16/2026
Aluminum alloy wheels have become the preferred choice over steel wheels due to their lightweight nature, enhanced aesthetics, and contribution to improved fuel efficiency. Traditionally, these wheels are manufactured using methods such as Gravity Die Casting (GDC) [1] or Low Pressure Die Casting (LPDC) [2]. As vehicle dynamics engineers continue to increase tire sizes to optimize handling performance, the corresponding increase in wheel rim size and weight poses a challenge for maintaining low unsprung mass, which is critical for ride quality. To address this, weight reduction has become a priority. Flow forming [3,4], an advanced wheel production technique, offers a solution for reducing rim weight. This process employs high-pressure rollers to shape a metal disc into a wheel, specifically deforming the rim section while leaving the spoke and hub regions unaffected. By decreasing rim thickness, flow forming not only reduces overall wheel weight but also enhances strength and

Development of a GUI-Based Pitch Sequence Optimization Tool for Tyre Noise Reduction2026-26-03301/16/2026
Minimizing tyre noise is essential for enhancing ride comfort, especially in electric vehicles where the absence of engine noise makes tyre-generated sound more prominent. This work presents the development of a GUI-based pitch sequence optimization tool to support tyre design engineers in generating acoustically optimized tread sequences. The tool operates in two modes: without constraints, where the pitch sequence is optimized freely to reduce tonal noise levels; and with constraints, where specific design rules are applied to preserve pattern consistency and manufacturability. This tool plays a pivotal role in the tire development process, serving as one of the key evaluation criteria for tread pattern approval before mould fabrication. By enabling engineers to generate balanced, low-noise pitch sequences that align with both acoustic targets and engineering constraints, the tool facilitates faster design iterations and smooth integration with downstream processes.

Study of Style wheel rim failure Due to Rim and disc assembly interference2026-26-05411/16/2026
This study focuses on the investigation of wheel rim failures near weld zone during repeated cornering induced by interference between the rim and disc during the wheel manufacturing assembly process. Strain gauges were employed to capture real-time stress and strain distributions at critical zones during interference fitting. The experimental results revealed that improper interference levels lead to significant stress concentrations, often surpassing the material's elastic limit, initiating micro-crack formation and promoting fatigue failure. Detailed strain analysis indicated that both radial and axial stresses contribute to long-term structural degradation. The study highlights the critical role of dimensional tolerances, surface finishes, and assembly forces in minimizing stress-induced failures. Recommendations are provided for optimizing design and assembly practices to enhance the durability and reliability of automotive wheels.

"Design and process Optimization of Suspension Components Under RWUP-based Loading Conditions"2026-26-05141/16/2026
Title: Challenges faced during design and manufacturing of POM (Polyoxymethylene) ring in Macpherson strut suspension. Abstract: Designing and manufacturing a POM (Polyoxymethylene) ring for a MacPherson strut suspension system brings a unique set of challenges due to the high-performance and durability demands for Indian road application. POM ring along with bump used in the shock absorber is designed to absorb the strong shock coming from the road inputs when suspension travel reached to the maximum limit there by absorbing the impact energy and preventing it from transferring it to the body. A bump stopper for a suspension of a vehicle is made of poly urethane (PU) and POM ring (Polyoxymethylene). The bump stopper forms of a bellows shape during the absorption of impact energy. Bellow or wrinkle in which concaves and convexes are repeated is formed on the outer surface of the bump stopper. POM ring is placed in the concaves of bump stopper which will define load, deflection

Virtual Paint Shop: Automotive E-coating Process2026-26-03651/16/2026
The automotive paint shop is one of the most energy-intensive processes in vehicle manufacturing. This drives automotive OEMs to continuously improve production efficiency and reduce operational costs through digital twin technologies. Additionally, the push for shorter time-to-market emphasizes the need for simulation-based manufacturing processes—such as virtual testing and CAE simulations—to enable faster, data-driven decision-making early in the product development cycle, ultimately reducing cost and development time. Among the various stages in the paint shop, two of the most critical are: 1. Electro-dip coating (E-coating), also known as Electro-Deposition coating, which applies a corrosion-resistant primer to the Body-in-White (BIW). 2. Oven curing, which ensures the primer is properly bonded and cured for long-term protection and finish quality. To optimize these processes, a Dip-Drain-E-Coating simulation was developed using Siemens Simcenter STAR-CCM+. This simulation

Effect of pipe bending by rotary tube bending process on durability of frame structure2026-26-03701/16/2026
For Original Equipment Manufacturers (OEMs), ensuring the overall quality of two-wheeler frames hinges on robust process capability and meticulous design considerations. A comprehensive Computer-Aided Engineering (CAE) simulation approach, integrating manufacturing processes and design elements, is vital for achieving optimal durability. This study focuses on developing such an approach through detailed finite element analysis of Cold Electric Welded (CEW) annealed round pipes used in frame construction. We simulate the bending process, capturing structural deformation and residual stresses. A 3D mechanical model with realistic tooling geometries and contact interactions accurately represents shape changes, ovality, and wall thickness redistribution. Unlike Electric Resistance Welded (ERW) pipes, CEW pipes, due to annealing, offer a stress-free initial state, allowing precise deformation analysis. Simulation results demonstrate significant geometric alterations in the bend zone

Evaluation of Shear Trim Edge in HSLA Steel for Automotive Application2026-26-02861/16/2026
Quality of the Shear Trimmed edge of HSLA 550 steels is significantly affected by process variations such as Shear Trimming Clearance, trim tolerance, burr height and clamping force. All these parameters largely influence the characteristics of the Shear Affected Zone, a region on sheet metal where it undergoes deformation during the trimming process. The Shear Affected Zone is predominantly vulnerable to failure due to work hardening and the effects of strain rate, induced by the tonnage during the trimming operation. To assess the edge ductility of these materials, Tensile, Fatigue Strength, Die Punch Clearance, Roughness and Hardness Tests are carried out. These tests are crucial for applications that demand high formability and resistance to edge failure. Virtual simulation of edge trimming operation using elastoplastic material models in LS-Dyna have been performed to gain insights into burr formation and damage evolution during shearing. These simulations act as a precursor to

Simulating Performance of Adhesive-Bonded Joints for Automotive Applications2026-26-04151/16/2026
Adhesive joining techniques have rapidly gained momentum in the automotive industry over the past decade, offering several advantages over traditional joining methods. The complex design requirements of modern automobiles have increased the demand for intricately shaped components, where conventional spot/seam welding and mechanical fastening are often not feasible. Unlike spot and arc welding, adhesives do not degrade the properties of the substrate. Moreover, they enable the joining of components made from dissimilar materials, thus contributing to the overall weight reduction of assemblies. Adhesives also provide damping effects, reducing noise, vibration, and harshness (NVH), thereby contributing to a quieter and more comfortable ride. Additionally, adhesives enhance structural integrity by distributing stresses more uniformly across the joints. Consequently, understanding the simulation and failure prediction of adhesive joints has become essential. Traditional failure criteria
