Study of Style wheel rim failure Due to Rim and disc assembly interference2026-26-0541To be published on 01/16/2026
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.

Optimization of Battery Mixing Strategies to Enhance Electric Vehicle Performance and Efficiency2026-26-0209To be published on 01/16/2026
Fleet operators increasingly contend with a patchwork of battery‑pack generations that remain electro‑chemically compatible yet differ markedly in capacity, internal resistance and residual life. Conventional “like‑for‑like” replacement policies oblige service providers to retain costly legacy inventories or to install brand‑new packs in ageing vehicles—both scenarios inflating warranty exposure and material waste. Deploying a rational mixing strategy for packs of different vintages therefore offers a compelling path to lower costs and improve sustainability, but industry‑wide guidance is limited and confidence in performance impacts remains low. This paper presents an optimisation‑driven framework that determines when and how heterogeneous packs can be paired at the moment of integration while maintaining vehicle performance targets and minimising life‑cycle cost. The methodology combines: a physics‑based electro‑thermal performance model parameterised for discrete state‑of‑health

The optimization of new generation trucks is crucial for enhancing performance, efficiency, and compliance with regulatory standards. In the conventional product development, the manufacturer often optimises the powertrain to meet the stringent emission which might not account for the customer usage. This study uses the simulation-based approach that integrates customer usage with help of logged vehicle data across various applications, to develop a single engine platform equipped with multiple drivetrain options. Using a data driven approach, real-world usage pattern analysis is conducted to identify key performance metrics required to optimize the driveline components tailored to each application. Additionally, the impact of certification requirements on vehicle performance is examined to ensure compliance while maximizing the benefits of the proposed optimization strategies. The findings of this research will provide valuable insights for manufacturers and fleet operators, enabling

A strategic approach to the selection of switchgear and busbars for EV battery packs2026-26-0165To be published on 01/16/2026
With the rising adoption of electric vehicles (EVs), the need for robust and efficient power distribution systems has become increasingly important. This paper outlines a strategic method for selecting switchgear and busbars in EV battery packs, emphasizing key factors such as safety, energy efficiency, thermal control, and future scalability. Proper optimization of these components can significantly improve performance, minimize power losses, and ensure durability under demanding operating conditions. The design and selection of battery conducting components, such as switchgears and busbars, are typically based on the maximum continuous and peak current capabilities of the EV battery pack. While this approach ensures that the components can withstand extreme conditions, it often leads to over-engineering, resulting in unnecessary costs and added weight. However, this method overlooks the dynamic power demands of the vehicle, which fluctuate based on driving conditions and usage. Real

Analysis of the Water Exit Process of a Vehicle Based on Fluid-Structure Interaction Analysis2025-99-000210/10/2025
The study investigated the fluid dynamics characteristics of a navigational body during emerging from water. It focus on the patterns of pressure and velocity changes in the flow field. Using numerical simulation methods, we explored the fluid-structure interaction between the navigational body and the surrounding water. It revealed the phenomenon of decreasing impact forces on the object’s surface over time and the resulting changes in surface pressure distribution. Additionally, the study demonstrated the dynamic evolution of the velocity field during emergence. This further elucidated the impact of flow state changes on the navigational body’s motion performance and stability. These findings would provide important theoretical foundations and technical support for optimizing the design of navigational bodies.
