摘　　要：针对RV减速器主轴受力问题,在采用Romax对主轴承进行受力分析时发现,由于影响参数的量级和跨度不同,不能确定各参数对主轴承的受力影响程度。基于此,提出了模糊综合评判的方法。结果表明,摆线轮针轮数和摆线轮节圆半径对主轴承的受力影响最大。采用熵权法和灰色关联度对各参数对主轴承受力影响程度进行验证,由模糊综合评判方法得出的结果和熵权法及灰色关联分析法得出的结果一致,进而验证了模糊综合评判法的有效性。Aiming at the RV reducer spindle force problem,and based on the Romax force analysis of the main bearing,it is found that due to the different magnitude and span of the impact parameters,the influence degree of each parameter on the spindle bearing force cannot be determined.Based on this,a fuzzy comprehensive evaluation method is proposed.The results show that the number of cycloidal wheel pins and the radius of cycloidal wheel pitch have the greatest influence on the force of the main bearing.The entropy weight method and grey relational degree are used to verify the influence degree of each parameter on the bearing capacity of the spindle.The results obtained by the fuzzy comprehensive evaluation method are consistent with the results obtained by the entropy weight method and grey relational analysis method,which verify the effectiveness of the fuzzy comprehensive evaluation method.
