Influence of Chassis Frictions on Vehicle Dynamic Behavior: Analytical Study

Article of Honda R&D Technical Review Vol.23 No.2

Summary

An extensive analytical study was performed to analyze the influence of chassis frictions on vehicle dynamic behavior and identify the relative importance of frictions in different locations of a chassis system. First, a multi-body simulation model of a full vehicle was developed that integrates customized friction functions in all major chassis joints. The model was correlated with measurement in chassis kinematics, compliance, system-level frictions, and vehicle dynamic performance. Using the simulation, along with the confirmation of two test vehicles, seven key vehicle performance areas affected by chassis frictions were identified. This was followed by a thorough sensitivity analysis to identify frictions that have high influence on each of those performance areas. Common influential frictions that have a considerable influence on multiple performance areas were identified.
