Study on Two-phase Genetic Algorithm Optimization Design of Dual-path Split-torque Gear Transmission System

功率分支齿轮传动在船舶和航空动力传输中应用广泛,对其开展优化设计研究对进一步减小质量、提高承载能力有重要意义。以功率二分支齿轮传动为研究对象,选择基于生物遗传间断平衡理论的两相遗传算法为优化方法,以传动系统体积最小为目标函数,在保证齿轮满足不干涉、配齿条件以及强度要求等前提下,建立了功率二分支齿轮传动优化设计模型并获得了优化结果。结果表明,两相遗传算法具有更加合理的优化性能,设计出来的齿轮体积较之常规设计减小了20%。

Split--torque gear transmission is widely used in power transmission of shipbuilding and aviation. Studying on its optimal design has a huge significance on further reducing weight and im- proving load capacity. With considering dual-path split-torque gear transmission as the study ob- ject, choosing two-phase genetic algorithm which is based on the theory of punctuated equilibrium as optimization method, and taking minimum volume of gear transmission system as target function, in the premise of ensuring gear non-interference, teeth fitting, strength requirement conditions and so on, a dual-path split-torque gear transmission optimization model is established, and a optimal re- sult is obtained. The result shows that two-phase genetic algorithm has a better optimal capacity, and the gear volume using this message has a 20% drop-off compared with conventional design.
