Transmission Evaluation of Planar Single DOF Multi-loop Mechanisms
摘要
Abstract
Based on Assur group theory,the structural features of planar single DOF multi-loop mechanism are analyzed.According to topological relationship between Assur group and input/output links of the mechanism,the general description method of planar single DOF multi-loop mechanism is given.Based on this,the transmission of Assur group is defined with the concept'virtual coefficient'in screw theory.The transmission index of single DOF multi-loop planar mechanism is given accord to the connection relationship of Assur group.Finally,one cam-linkage mechanism is proposed as an example for the transmission analysis compared with the traditional methods.The result proves that the proposed method is closely related to the actual working state of the mechanism and verifies the effectiveness of the transmission index.关键词
