A Virtual Prototyping System for Design for Assembly, Disassembly, and Service

Abstract

Design for the life cycle practices enable the improvement of a product’s recycling, disassembly, and service characteristics, to name a few. In this paper, an approach to virtual prototyping is presented that supports product Design For Assembly, Disassembly, and Service (DFADS). The VP-DFADS system enables a designer to construct a product model, to interactively simulate an assembly, disassembly, or service process for that product, and to formulate and solve a simultaneous product/process design problem. Specific research objectives underlying this project include a reduction in VP model construction times, an improvement in information with which designers make DFADS decisions, and the development of a design synthesis method for DFADS. Although automated reasoning and synthesis technologies are outlined, the emphasis in this paper is on the integration of these technologies into the VP-DFADS system and on the usage of the system in supporting DFADS decisions. An application of the VP-DFADS system to automotive center console design illustrates the potential usefulness of the VP-DFADS approach.

Research on Repair Time Modeling in Virtual Maintenance Simulation

“…SRL laboratory [3]Georgia Institute of technology in virtual disassembly projects in the repair process of decomposition, they use the method of object oriented task to make "work (Task)" into "operation (Operation)", the basic contains most of the information operation. Lowa University's CAD center Ranko Vujosevic [4] will repair action to repair operation, disassembly sequence layer, removing step layer and macro motion, macro model layer, which can reflect the disassembly sequence repair operation choice, and for each sequence can provide a basis for the macro motion model of virtual disassembly simulation. American Pennsylvania University HMS center [5] has long been engaged in human body modeling and simulation research, basic motion function which mainly uses Jack software to provide the repair process simulation, have in-depth study compiled in repair simulation program.…”
