Dependency of Gear Honing Machine Processing Accuracy on Machine Vibration and the Vibration Reduction Considering Contribution2024-32-002004/18/2025
In recent years, accurate gear processing is required for various products to improve efficient power transmission and small noise and vibration. On the other hand, the accuracy tends to be worse by high speed processing for increasing production efficiency. Therefore, we investigated relationship between gear honing machine vibration and the accuracy. The vibration acceleration of the honing machine was measured at various conditions, and the gear accuracy was measured after processing. As results, the accuracy was observed to be affected by both the original gear accuracy before honing processing and the gear secondary rotational vibration of the machine in operation. Subsequently, we applied transfer path analysis (TPA) to investigate which directional force in operation increased the vibration. As the results, the contribution from the input force at gear processing point along normal direction was the main contributor. Then, vibration transmission characteristics of the machine

Enhancement in Tribological Properties of Squeeze Casted A356 Alloy with Post Processing Techniques through Heat Treatment and Heat Treated cum Shot Peening Approach2021-28-026510/01/2021
Primary objective of this research work is to study the effect of heat treatment and heat treated cum shot peening processes on the tribological properties of squeeze casted A356 Alloy. The proposed alloy has wide range of applications in automobile industries due to its appreciable mechanical and tribological properties. Squeeze casting is an efficient economic and promising processing route for fabricating aluminum alloy with improved properties and pore free structure. Further the properties can be improvised through post processing technique like heat treatment and heat treated cum shot peening approach and also residual stresses are removed as a result of heat treatment process. So, this research work aims to investigate the effect of post processing approach on the tribological properties of squeeze casted A356 alloy. A wear and friction characteristics of the prepared samples were tested using pin-on-disc tribometer apparatus under dry sliding condition of load 10, 20, 30 and

An alternate CED process for low volume BIW manufacturing with single stage vertical dipping2021-28-022710/01/2021
Body in White (BIW) is a major assembly in an automobile. It is made of sheet metal components that are welded together by Resistance spot welding. Assembled BIWs are put through an anti-corrosion process called Cathodic Electrodeposition (CED) and baked to set the CED coat. CED process has an elaborate sequence of rinse cycles and coat cycles. Single stage dipping stations are used for coating large volumes of smaller components. The high-cost multi-stage setup is a commonly used process in large scale BIW manufacturing systems. In the context of small-scale batch production or prototype builds, the extensive setup is not viable. This paper studied the feasibility of CED coating large BIWs in a single stage setup. Multiple process modifications explored to establish single stage setup for BIW coating. Process capability and effectiveness of utilization was studied. The results were analyzed, and the comprehensive process chain was concluded and discussed for implementation.

A Case study on Effect of subsequent operations on shotpeened Crown Wheel Pinion (Hypoid Gear set) & Compressive Residual Stress analysis2021-26-025209/22/2021
Abstract: The prime function of crown wheel pinion is to receive the power from Transmission & distribute to two-wheel Ends. Doing so these members will experience the tremendous Bending Fatigue. Shot peen is the one of the latest technologiesused to improve the bending Fatigue of the CWP. In this particular case- 6 CWP are taken for the Study to understand the effect of the operations after shot peen process. 3 Samples are named as Batch A, another 3 samples are named as Batch B. Both the batch CWP are shot peened. Then as a regular production Practice the Batch A CWP are process through Hard TurningAbrasive Lapping Hot Lubriting (Mn Phosphate)Fully Finish Ready for Assembly. Then Both the Batch A & batch B samples are taken for Residual Stress analysis using X-Ray Diffraction Technique. The measurement location is 50 microns below the surface. The results tabulated,found that Batch A samples shows decrease in Residual stress relatively to Batch B.This evident that post operations

Powertrain Friction Reduction by Synergistic Optimization of Cylinder Bore Surface and Lubricant - Part 2: Engine Tribology Simulations and Tests2021-01-121709/21/2021
Since a significant percent of fuel in cars is consumed by friction, with powertrain friction being one of the chief culprits, the development of low friction powertrains is an important task [1-3]. The introduction of advanced surface finishing and coating methods, such as thermally sprayed coatings, self-lubricating hard coatings, mechanochemical surface finishing, helical slide honing etc. together with a shift towards low viscosity synthetic lubricants help further improve fuel economy and reduce GHG emissions. For passenger cars, a change from the legacy SAE 15W-40 grade to SAE 0W-20 brings on average 3-4% improvement in fuel economy under the NEDC or EPA conditions, and the subsequent migration to 0W-8 can bring an additional 2-3%. The primary obstacle to continually lowering lubricant viscosity is increased engine wear. The hydrodynamic lubricant film thickness is directly proportional to lubricant viscosity. Therefore, to maintain hydrodynamic lubrication, substantial

Battery Thermal Management Simulation - 1D+1D Electrochemical Battery and 3D Module Modeling on Vehicle System Level2021-01-075704/06/2021
Approaching engineering limits for the thermal design of battery modules requires virtual prototyping and appropriate models with respect to physical depth and computational effort. A multi-scale and multi-domain model describes the electrochemical behavior of a single battery unit cell in 1D+1D at the level of intra-cell phenomena, and it applies a 3D thermal model at module level. Both models are connected within a common vehicle simulation platform. The models are discussed with special emphasis on battery degradation such as solid electrolyte interphase layer formation, decomposition and lithium plating. The performance of the electrochemical model is assessed by discharge cycles and repeated charge/discharge simulations. The thermal module model is compared to CFD reference data and studied with respect to its grid sensitivity. The temperature evolution of a module is simulated for enabled and disabled degradation equations revealing a very high impact of the degradation equations

Optimizing the Piston/Bore Tribology: The Role of Surface Specifications, Ring Pack, and Lubricant2020-01-216709/15/2020
The present study looks into different possibilities for tribological optimization of the piston/bore system in heavy duty diesel engines. Both component rig tests and numerical simulations are used to understand the roles of surface specifications, ring pack, and lubricant in the piston/bore tribology. Run-in dynamics, friction, wear and combustion chamber sealing are considered. The performance of cylinder liners produced using a conventional plateau honing technology and a novel mechanochemical surface finishing process - ANS Triboconditioning® - is compared and the importance of in-design “pairing” of low-viscosity motor oils with the ring pack and the cylinder bore characteristics in order to achieve maximum improvement in fuel economy without sacrificing the endurance highlighted. A special emphasis is made on studying morphological changes in the cylinder bore surface during the honing, run-in and Triboconditioning® processes. It is demonstrated that the Triboconditioning
