シミュレーションの活用による品質工学の取組み

抄録

Simulation has many advantages over the use of prototypes: not only is it lower in cost, but results are also obtained in a shorter time, and quantities that would be difficult to measure on an actual product can be evaluated. This paper concerns parameter design carried out by simulation to stabilize the functions of an automobile suspension system. CAE (computer aided engineering) tools were used for efficient design; tuning was carried out to improve functionality by the standard S/N ratio, and to obtain a suspension with a shock mechanism capable of absorbing a large amount of energy. The analysis was automated from the system side, enabling extensive calculations to be carried out. This experience may be of reference in the future use of simulation in quality engineering.
