At the end of the dissertation, the taper roller bearing CAD system was developed. In this software system, the optimal design realized by Synthesized Constrained Dual Descent Method (SCDD), IGA, ISA and GSA is included.

• 最后开发了圆锥滚子轴承优化设计CAD系统，并将综合约束函数双下降法(SynthesizedConstrained Dual Descent Method简称SCDD法)、改进的遗传算法、改进的模拟退火算法、遗传模拟退火算法实现圆锥滚子轴承优化设计作为系统优化设计主模块底下的四个子模块。
