摘　　要：结合CAXA和SolidWorks对直齿圆柱齿轮进行三维建模,利用SolidWorks内置插件Motion对齿轮进行运动仿真,利用SolidWorks SimulationXpress对齿轮进行应力分析,最后以齿轮厚度为设计变量、齿轮安全系数为状态变量、齿轮质量为目标函数,建立了齿轮的优化模型,进行优化设计,使齿轮在保证安全系数的情况下质量最小化,降低了材料成本,提高了经济效益。The 3D model of spur gears is constructed by combing CAXA and SolidWorks, and the motion of the gear is sim- ulated by using SolidWorks plug - in Motion. Then the stress analysis is carried out with SolidWorks SimulationXpress. Fi- nally, the optimization model of gears is established with the gear thickness as the design variables, gear safety coefficient as state variables, and the gear weight as the objective function. Based on SolidWorks SimulationXpress, the gear optimal de- sign is worked out to minimize the gear weight on the premise of ensuring its safety coefficient. This results is low material cost and good economic benefits.
