Non-linear CAE Technology to Balance Handling and Ride Comfort

Article of Honda R&D Technical Review Vol.29 No.1

Summary

Honda’s in-house vehicle dynamics simulation tool has been enhanced to balance ride comfort and handling performance more effectively. To deal with the characteristics that affect ride comfort, ride comfort tire model was newly introduced and its parameter identification method was developed for better reproduction of vibration transmission characteristics from road to tire. In order to consider suspension vibration transmissibility from tire to vehicle body, simulation models for rubber bushings, ball joints, and dampers were newly developed that can consider amplitude and frequency dependence. Their parameter calculation methods were also developed. In addition, to enhance the reproducibility of a vibration originated from engine, a hydraulic engine mount model that can reproduce amplitude and frequency dependence as well as its parameter identification method were developed. By incorporating the above technologies into our vehicle dynamics simulation tool, it became possible to study design more detailed specifications to balance handling and ride comfort performance at early stages of vehicle development.
