Abstract
Acceleration shock is due to a low frequency fore and aft vibration that is induced by rapid transient change of engine torque. And mechanism of vibration and force of transient torque was analyzed. The results are as follows. (1) Vibration of power train is minimized when resonance frequency of engine roll is equal to torsional resonance of power train. (2) This minimum condition is not feasible for vehicle with high gear ratio. (3) Quantitative evaluation of transient engine torque is calculated with excitation spectrum that is studied in this paper.
