An assembly modelling system for dynamic and kinematic analysis

Abstract An assembly modelling system, with which a designer can interactively create an assembly of components ready for dynamic analysis, has been developed. In this system, an assembly model is created from the mating conditions between the components in the assembly, and then most of the information required for the dynamic or kinematic analysis packages is derived. For this development, the following problems have been solved: creation of assembly data structure, structuring of assembly data, derivation of joint information, inference of each component's position, and creation of joint coordinate systems. Through this work, the designer can easily model an assembly by assigning mating conditions, and check the dynamic or kinematic performance with the automatic creation of inputs for the assembly analysis packages.
