Assembly of parts
In today’sglobal situation, two main things are significant for the industry: cost reduction and environment protection. Since the late 70’sit has been developed that the assembly procedure normally signify one third of the product cost. Hence, it is essential to design appropriate plans for parts assembly: manufacturing, and disassembly: recycling.
A realistic assembly procedure can increase efficiency, cost reduction and improve the recycling of product. To overcome these problems, various simulations based on digital mock-ups of products are required. Even though modeling and analysis software, presently applied at various stages of the Product Development Process, can suggest results to several of the above stated needs, the progress of a committed assembly and disassembly combine simulation stage is still a need.
To attain an optimum assembly method, various complex software for assembly analysis and, as well as simulation programs based on multi agent methods or which apply contact data between assembly components, were created. Newly, Virtual Reality (VR) has broadly developed towards Assembly realistic simulation.
As the contact between objects is at the basis of the assembly simulations need 3D objects shapes, the contact detection is addressed here as the first step in the Assembly simulation process. The equivalent procedure establishes links between shapes, contact mock-ups and component kinematics, which gives a basic set of meaningful data
All mechanical parts are applying one of the common CAD modelers. Thus, the existing assembly modules of 3D CAD software and their definite method to modeling assemblies have a tough influence on how products are calculated. Also, for the realistic simulation, the data exchange CAD to Virtual Reality is one of the significant problems presently faced by the virtual prototyping community.
