摘要
针对传统轴承刚度计算方法计算过程复杂,计算结果正确性存疑的问题,提出了一种斜弹簧计算方法,以角接触球轴承为例,推导了受联合载荷、高速运转和仅受中心轴向载荷、中低速运转2种极端情形下的轴承刚度计算公式,斜弹簧计算方法整个过程无需微分和矩阵运算,物理意义清晰,正确性能够自证,计算过程简洁,计算精度高.并与虚功原理法、刚度投影法、准静态模型的增量法进行对比,结果表明:与虚功原理法误差较小,进一步证明了斜弹簧计算方法的正确性;与刚度投影法、准静态模型的增量法误差较大,两者所依据的物理基础不实的计算结果正确性存疑.
Abstract
An inclined spring calculation method is proposed to address the problem of complex calculation process and questionable correctness of calculation results in traditional calculation methods for stiffness of bearings.Taking angular contact ball bearings as examples,the calculation formulas for stiffness of the bearings are derived for two extreme cases:combined load,high speed operation and only central axial load,medium and low speed operation.The proposed method does not require differentiation or matrix operations throughout entire process,with clear physical meaning,self proving correctness,concise calculation process and high calculation accuracy.Compared with virtual work principle method,stiffness projection method and incremental method of quasi-static model,the results show that the error is smaller compared with virtual work principle method,further proving the correctness of the proposed method;the error is larger compared with stiffness projection method and incremental method of quasi-static model,and the analysis points out that the correctness of calculation results based on false physical basis of both methods is questionable.
