Aiming at the problem of structure design in reverse-design of mechanism,a structure mapping method based on reverse solving of locus and motion(RSLM)is presented.The mechanism scheme meeting the requirements of geometric and structural features is obtained through RSLM.The element instance subsets related to component are established based on the element type mapping, pair structure type mapping and design knowledge mapping between components and elements layer by layer.The assembly position mapping of elements is established based on the topological structure information of mechanism scheme,and the product modeling of structure mapping is realized.The algorithm program and prototype system of product structure mapping based on RSLM are devel- oped.Application samples show that the method implements the integration of scheme design,as- sembly design and structure design,and modeling for product structure mapping based on RSLM. The feasibility of assembly is analyzed in scheme design that contributes to reducing the design error, and raising the design efficiency and quality.
