【Abstract】 The shape optimization of free-forging multiple stepped shaft is discussed. Decisive theory is employed to establish "rule constraint" based on reasoning, which overcomes the difficulties of constructing a computational constraint model. Compared with enumeration approach, the discrete variable direct searching algorithm seems efficient and reliable.更多还原
