摘要
本文应用决策分析理论建立了基于推理的自由锻台阶轴锻件形状优化的“规则约束”模型,解决了约束条件解析模型的表达困难;构造了台阶轴锻件形状优化的离散变量直接搜集算法,并与枚举法结果相比较,以实例验证了算法的可靠性.
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.
