Abstract
Recently the automotive industry has focused on reducing product development time to correspond with the customer’s evolving needs. Decreased product development time shortens the quality assurance period, which makes it difficult to guarantee the quality of mass produced products. Therefore a conflict between development time and quality assurance occurs which is exacerbated by the markets constantly rising performance baselines. To solve this problem, many companies have tried to forge a system that verifies the various steps of development by computer simulation in advance; from design right through to production. But automotive supply companies have difficulties building such systems because the software is expensive, there are few experts, and the system often fails to meet a company’s individual needs. In this paper, to overcome these problems, we built the process, reduced verification time for real time verification, improved reliability of flexible assembly simulation, and made a theory concerning quantitative valuation. The result of the virtual design verification is presented to developer more effectively and more exactly.
This paper presents how we have made the virtual validation process more effective and the methodologies that resulted in the increased reliably. Concepts are tested in an automotive case-study for verifying design concept and quality in door trim. Through the virtual design validation process built in this paper, we can expect reduced development time, and furthermore that the high quality demands of the market are satisfied simultaneously.
