The multi-objective optimization design for pin gear transmission based on differential evolution

为缩短销齿传动的设计周期,降低产品成本,依据弹性流体动力润滑理论和齿轮啮合原理建立销齿传动的冷胶合强度条件。以齿间最小油膜厚度最大(倒数最小)和销齿传动中心距最小作为设计的追求目标,摈弃传统的多目标优化设计方法,利用修正的微分进化多目标优化算法对范例进行分析计算。优化过程及结果表明,修正的微分进化多目标优化算法能够有效地提高产品的综合经济技术指标。

To shorten the design cycle of the pin gear transmission and reduce the product cost, it is crucial to establish the cold scuffing strength conditions of pin gear transmission according to the the- ory of elastic hydrodynamic lubrication and the principle of gear engagement. The highest minimum oil film thickness among teeth and the minimum center distance were set as the pursuing goal of de- sign while abandoning the traditional multi-objective optimization design method. The example was analyzed and calculation by the modified multi-objective optimization algorithms based on differential evolution. The optimized process and result showed that the modified multi-objective optimization al- gorithms could increase effectively the products＇ synthesize economical and technical indexes.
