CAE Analysis of Effects of Conditions in Spinning Forming on Shape Defects of Automotive Exhaust Part

自動車排気系部品のスピニング加工での 不具合発生要因のCAE 成形解析

The experiments were conducted on pipe diameter reduction by spinning forming process with ferritic stainless steels. The target shapes of this study are the automotive exhaust parts, such as catalytic converters or sub-mufflers. Effects of the several forming condition factors on the geometrical property or defects of the parts are clarified. Computer aided engineering (CAE) simulation model was also developed for spinning forming. The calculated results were in good agreement with actual specimens not only in thickness distribution but also in shape of buckling defect. The results suggest that CAE simulation could be a helpful tool to obtain optimum forming conditions.排気系部品のスピニング加工について成形シミュレーションを開発した.その結果をフェライト系SUS鋼材での実機加工実験と比較検証した.シミュレーションでは加工後の板厚分布のみならず,形状不良についても精度の良い再現が得られ,実機の不具合事象の予測や対策に有効に活用できると考えられる.
