whether this is a problem-dependent number. Indeed, it is uncertain whether the feasibility percentage is a good indicator of the optimum switching moment. Similarly, further (broader) studies may reveal more effective ways of deciding on the best moment to switch back for a another constraint satisfaction phase.

摘要 多级减速器设计空间通常有严重短缺。而这方面非常需求找到好的算法,但成功的优化方法比传统的启发式算法有更大的潜力,同时可以更好地理解权衡各种目标(如使用寿命和整体重量)。在这里我们解决一个二级螺旋齿轮传动设计问题(完整的尺寸和选择轴、轴承、减速器外壳等),利用两相演化算法这种方法法可以拓展出不一样的减速器包含额外的阶段或不同的布局。

介绍
多级减速器的设计的复杂性在于确定其子系统之间的设计变量困难而且连接棘手。换句话说，在优化的组件装配中一个最佳的减速一般是不隔离的，许多传统的设计启发式忽略了一个事实，例如，一个齿轮的宽度和中心距的必然选择的影响可能会产生一个最低的质量，整体负重，但这级联负重5月通过的设计过程中的后续步骤的选择（轴的大小，下一步阶段，轴承，外壳等），最终导致较大的减速比，如果已经有轻微的妥协，第一选择负荷。
一个典型的例子可能会选择比最优齿轮直径（和相应的更大的接触面宽度）较小，可能会产生一个有点沉重的负荷，但更紧凑的布局，因此，要轻得多的壳体，这是值得一提的影响，虽然这在现实中的总体目标，往往是直接和少得多，远远超过在这个例子中默默无闻。,源Z自L优尔:文,论/文]网[www.youerw.com。 二阶螺旋齿轮减速器英文文献和中文翻译(7):http://www.youerw.com/fanyi/lunwen_51526.html
