Research On Technologies Of Assembly Simulation Based On Pro/ENGINEER

During the course of design and manufacture of mechanic product, Assembly is a very important process. Assembly in the traditional machine design is iterative after the physical models are made. It make the assembly process the bottle neck of the develop rate of new products. Based on the software of Pro/ENGINEER, the thesis studies the technology about assembly, the main works as follows:(1) The theories and technologies of assembly simulate are analyzed in this thesis. Include basic theory of assembly model set up, layout of assembly sequence, layout of aseembly path, collision detecting, part library etc.(2) Lodged the method of marking out assembly sequence in assembly skeleton, to implement the simulation of assembly, then set the condition of collision and the degree of simulation, to detect the collision of the assembly model. Introduced the idea of assembly model setting up, path layout and collision detection.(3)Use the theory of part family and family table based information to set up and manage part library, achieve the part replace during the assembly.(4)Integrate with the subject of The Design of The Hydraulic cylinder Used for Tridimensional Carport, use the method of TOP-DOWN design ,finish the conceptual design of the cylinder first, then set up the hierarchical model of the cylinder, finish the particular design of every part. Based on the module of Pro/E, use program to implement assembly simulation and collision detection. Use layout module to achieve TOP-DOWN design first, then set up assembly model, layout assembly sequence and assembly path. Use program to implement the assembly simulation and collision detection of the hydraulic cylinder.
