A New Matrix Expression Method for Whole Information to Describe and Analyze a Metamorphic Mechanism
摘要
Abstract
The paper discusses a matrix expression method for the configuration transformation of metamorphic mechanism.A matrix with whole information can describe all structural information on metamorphic mechanism,and we put forward its configuration transformation formula.The retrieval of the matrix can help obtain a lot of information,including number of kinematic joints,number of multiple components,number of multiple joints,size of multiple components,link connectivity,etc.The retrieval of its extension matrix produces kinematic parameters of the driving link and housing of the metamorphic mechanism.A case study demonstrates that this method can describe the driving link that is attached to another in the process of link increase or decrease and that the properties of the kinematic pair change obviously and completely without the need to renumber the initial configuration links.关键词
