Highly Reliable CAE Model, the Key to Strategic Development of New JIT

In recent years, the advanced manufacturing industry is engaging in a “global production strategy – for simultaneous achievement of QCD”. A close look at the development designing and production process stage reveals an excessive repetition of “experiment, prototyping, and evaluation” that prevents the “scale-up effect” generated in the bridging stage between prototyping, experiment, evaluation, and mass production. Consequently, what is urgently needed, is innovation to promote the advance from the conventional evaluation based development, that uses the prototyping and experiment process which had long supported highly reliable designing, to a CAE prediction based designing process. To accomplish this a new development designing technique was established, the “Highly Reliable CAE Model. This is the key to strategic promotion of the “Total Integrated Development Design model Advanced TDS” which utilizes the core element of the “Total Development System, TDS” of “New JIT”. In an effort to realize this, the author has proposed the “high quality assurance model for super short period development designing, a “Highly Reliable CAE Numerical Simulation” and demonstrated its effectiveness. As an application example, a simulation technology was developed for molding urethane foam and it was implemented as the “Production of CAE Software for Molding Automotive Seat Pads -Urethane Foam Molding Simulator”.
