Modeling and Controlling of CAD System for Planetary Gear Transmission

从设计方法的角度讨论了行星齿轮传动CAD系统的合理结构和内容 .介绍了优化设计模型 ,采用体积和模数同时极小化的设计目标 ,提出了分层优化策略 ;对不同的变量采用不同的目标函数 ,可使计算效率提高 ,优化结果的全局最优性和可靠性得到保证 .同时从实际设计需求出发提出了程序运行的控制方法 .

Rational structure and content of CAD system for the planetary gear transmission are discussed from the point of design method. The model of optimum design is introduced. The design objective of minimizing volume and module simultaneously are adopted, and a graded optimum strategy is presented. Different objective functions were used for the first time in accordance with different variables. As a result efficiency of calculation is raised, optimization of an overall situation and reliability of an optimum solution are ensured. Besides, the control methods of the program are put forward as a requirement of actual design.
