摘　　要：研究一种凸轮式扭转激振器的激振原理及凸轮曲线的建立方法。通过建立发动机曲柄滑块机构的力学模型,根据发动机气缸在曲轴不同转角的压力计算激振力矩,用数值计算的方法得到凸轮不同转角的升程,设计出凸轮曲线。最后分析了这种凸轮式扭转激振器的性能。The principle of actuating torsional vibration of a cam type torsional actuator and method of setting up cam contour was studied. A mechanical model of crank-slider mechanism of engine was set up, and the exciting torque was calculated by piston pressure at different rotary angle of crank, the camlobe lift at different angle was obtained by numerical computation methods, the suitable contour of the cam was worked out. At last the performance of this cam type torsional actuator was analyzed.
