Disassemblability of mechanical parts in automobile for recycling

Recycling of parts in automobile become important due to energy and environmental aspect. This study analyzes geometrical and material characteristics of parts, subassemblies and joining elements used in automobile. It also and analyzes disassembly mechanism between parts and sub-assemblies to improve disassembly process in a scrapped automobile. Disassembly is defined based upon disassembly mechanism and disassembly process. Finally, guidelines of design rules to improve disassembly is proposed and evaluated quantitatively using a case study of an automobile.
