The third paper reports on the analysis of mechanisms concerning the V10 engine exciting force and the rotational couple of forces. This paper reports on the analysis of roll axis mechanisms and the idling vibration simulation concerning the in-line 6-cylinders engine. By the way, the first paper describes the coupled vibration when the engine is supported under the center of gravity. With this coupled vibration, the elastic center is also influenced and its offset between the center of gravity and the roll center found out to be changed by the frequency. As far as the idling vibration simulattion is concerned, whole vehicle fine mesh model, by about 34 000 nodes, was made for better accuracy. The optimum design of many parameters is also conducted by the design of experiment so called Taguchi methods. Finally, the vibration level could be reduced much lower than that of the current system by the optimum design of the engine mount using the FEM.
