| 摘 要： | 将阶跃函数与牛顿第二定律相结合 ,对含间隙的平面连杆机构的分离与碰撞过程建立了统一的数学模型 ,方便了计算机编程的实现。考虑曲柄为非匀速运动 ,计入了杆件的重量及输入扭矩的变化的影响 ,采用了更为精确的求解方法 ,研究了因间隙引起的碰撞、冲击载荷诱发的非线性现象的机理 ,为机构的动态优化设计提供了新思路。

| Abstract: | We developed a unified dynamic model for separation and collision process of the linkage mechanism with clearance connections.It makes computer programming convenient. This model supposes the rotating speedof crank is changeable, and takes into account the effects of linkage weights and the variation of input torque. Besides, we adopted a more accurate method to solve the problem, studied the nonlinear phenomena mechanism arose from collision and impact load because of clearance connections. Thus this paper provides a new idea for the mechanism dynamic optimal design. |
