针对柔轮小型化、轻量化、高谐振频率的设计需求,以柔轮内径、长径比、厚径比和齿宽系数为研究变量,基于有限元软件Ansys,采用响应面法参数优化分析探究了各参数变化对柔轮固有频率的影响。结果表明,在柔轮小型化的设计过程中,柔轮内径和长径比的减小会引起其固有频率的增加,厚径比和齿宽系数的减小会导致其固有频率增大;但其固有频率都大于减速器工作的激励频率,因此,不会发生共振,不影响正常工作。
In response to the design requirements of miniaturization,lightweight and high resonance frequency of the flexspline,the inner diameter,aspect ratio,thickness-diameter ratio and tooth width coefficient of the flexspline are used as research variables. Based on the finite element Ansys,the response surface method parameter optimization analysis is used to explore the influence of the changes of each parameter on the natural frequency of the flexspline. The results show that,in the design process of the flexspline miniaturization,the decrease of the inner diameter and the aspect ratio of the flexspline will increase its natural frequency,and the decrease of the thickness-diameter ratio and the tooth width coefficient will increase its natural frequency,but its natural frequency is greater than the working excitation frequency of the reducer,and resonance will not occur to affect normal operation.
