Development of Technology for Predicting Engine Vibration During Start-Up by Applying a Model of Hydraulic Mount Characteristics

Abstract

In this study, technology for predicting engine vibrations during startup in vehicles equipped with a V6 engine has been developed. A model was formulated for the hydraulic mounts located at the front and rear of the engine, which takes into account not only frequency dependence but also amplitude dependence. The roll vibration input from the engine to the body, occurring during engine startup, was clarified using this model. As a result of this research, improvements to the characteristics of the hydraulic mounts can now be made more easily, while taking ride comfort performance into consideration.
