刚性链式直线推动装置的设计与动力学仿真分析

Design and Dynamic Simulation Analysis of Rigid Chain Linear Propulsion Device

刚性链是一种结构特殊的实现直线推拉功能的链条,具有占用空间小、安装方便等特点,国内目前尚没有结构合理的产品。将滚子链的设计方法与几何法相结合,设计了一种能够实现在较大行程内直线推拉动作的新型刚性链。对所设计的刚性链进行三维建模,将简化后的三维模型导入到ADAMS中进行动力学仿真,分析其受力情况。通过搭建新型刚性链试验台,试验验证了其合理性。

The rigid chain is one with a special structure.It is used to implement the linear push-pull function and is characteristic of small occupied space and convenient installation.There are currently no reasonable products at home.In this paper,the design method for the roller chain is used with the geometric method to design a new rigid chain which is used to implement the linear push-pull action in a large stroke.3D model of this rigid chain is established,and the simplified 3D model is imported into ADAMS for the dynamic simulation and analyzing the force.A new rigid chain test rig is built,and the rationality of its design is verified by experiments.
