| 摘 要： | 本文分析了当凸轮轴具有弹性变形时,单自由度与多自由度时凸轮从动体系统的振动。先建立键图。然后由键图理论出发,以凸轮位移(速度)作为输入变量,找出状态变量,列出状态方程,建立框图。对于单自由度还分析了当凸轮位移规律为(1)等加速度;(2)简谐运动;(3)摆线运动;(4)三次方多项式时由于振动使从动体质量块所具有动量的附加项(即实际与理论动量之间的偏离),所用的方法为拉氏变换。对于多自由度则说明了求各传递函数的途径。

| Abstract: | In this paper,the SDOF and MDOF vibration of cam follower system arc discussed,theelastic deformation of cam shaft is taken into account.The method used is to construct thebond graph first,then to fred the state variables and to establish state equations and block di.agrams according to the bond graph theory.The laplace transform method is used.As for theSDOF case,the deviation of momentum of follower lumped mass from its theoretical motionfor four types of cam input motion is analysed,i.e.(1)constant acceleration,(2)sine curve,(3)cycloid,and(4)cubic polynomial.As for the MDOF system,the procedure to find transferfunctions is given. |
