摘　　要：采用有限元法对双电机驱动双曲柄环板式针摆行星传动减速器箱体进行静力分析,通过按照设计图纸对三维实体进行精确建模,并设计符合工程实际的边界条件使计算结果尽量接近实际应力状态,并通过结果分析得出箱体的应力分布规律并找出箱体上应力的薄弱环节,采用增加筋的方法使应力分布更加均匀,并为进一步减轻减速器的重量提供设计依据.Finite Element Analysis (FEA) method is used to conduct static analysis of a cylinder block of double crank ring-plate cycloid reducer driven by double electromotor. Based on the driven design , complete 3-dimension solid model is established, and the best boundary condition is deternined to approxirnate practical stress distribution and weak stress point on the cylinder block through model solution. Some methods to improve the stress condition are proposed to provide importance design information for decreasing weight of future model.
