一种变结构机构的仿真分析与优化设计

在分析变结构堵渣机的结构特征基础上，利用ADAMS软件建立了仿真模型，通过机构的运动学、动力学仿真分析，找出了机构存在的主要问题；并对机构进行了优化及无过约束的自调结构设计．优化效果表明：堵渣机的各项性能得以提高，其工作更加稳定可靠；改善了机构的自适应性能，消除了堵渣机对外界工作环境的敏感性；为变结构机构的设计提供了一个新的方向．

Simulation and Optimum Design of a Variable Structure Mechanism

By using ADAMS/view,a simulation model of stopper is established which is based on analysis of its characteristics of variable structure,some main problems of stopper are found by motion simulation analyzing,and optimization and self-adjustable structure without overconstraints of stopper is also made.The result of the analysis shows that performance of stopper and ability of self-adaptation are improved with the benefit of more reliable working process and less sensitivity to environment.A new way of designing variable mechanism is provided.
