Abstract

The deployable assembly mechanisms generally consist of many identical mechanism modules, and have lots of loops and common constraints. According to that features, a high efficient method of the mobility analysis for the deployable mechanisms based on the nullspace of single module is proposed for the first time in this paper. By the assembly of the nullspace of each mechanism module with consideration of the constraints of the connections, the mobility and instantaneous kinematic features of the whole assembly mechanism can be obtained. This method is adopted to analyze the mobility of several kinds of deployable assembly mechanisms which are assembled following the rule of three types of modules’ assembly. The examples presented in this paper demonstrate that the method is better adaptive to analyze this kind of mechanisms and suitable for the computer programming.
