基于变胞原理的变自由度机构拓扑型分析

变自由度机构是一类具有特殊用途的机构。根据自由度的变化规律对变自由度机构进行了分类;利用变胞机构原理和拓扑理论对变自由度机构自由度的变化过程进行了构态变换描述。提出了一种对不同类型的变自由度机构进行拓扑型分析的“杆-杆”合并的新方法,由于把机构的型分析问题转化为矩阵计算,该方法可推广应用于更复杂的问题,并有利于在计算机上进行机构型分析。通过实例对该方法进行了验证。

Topological Type Analysis of the Variable Freedom Mechanism Based on the Metamorphic Principle

Variable freedom mechanism is a mechanism which has a special purpose and it is classified by the change law of freedom in this paper.The configuration was described to the process of mobility that can be changed in variable freedom mechanism with principle of metamorphic mechanism and topological theory.Based on these,a new kind of method about type analysis of the variable freedom mechanism was proposed by the method that a link is attached to another link.Because the method of the type analysis was transformed into matrix operation,it can be used for more complex problems,and processed by computer;The research results possess major guidance significance to the theoretical research on type synthesis of variable freedom mechanism and other theoretical research.Finally this method is verified through two practical examples.
