Development of Simulation Model for Active Control Engine Mount

Article of Honda R&D Technical Review Vol.16 No.1

Summary

This paper presents the development of an active control engine mount (ACM) model required to study passive characteristics and control inputs of an ACM, which absorbs increased 1.5 order vibrations caused by three-cylinder operation in a V6 engine. By integrating a dynamic model of the moving parts of an actuator into a conventional hydraulic engine mount model, resonance due to two fluid orifices are expressed. As a result, the ACM model capable of reproducing passive, active and unit characteristics with high accuracy is established. In addition, this actuator force value is obtained with this model to cancel the sub-frame transfer load generated by engine vibrations.
