摘　　要：传统的计算滚子接触载荷与接触变形的方法计算量庞大,易出现系统崩溃的情况。采用等效替代的方法,建立了3种等效数学模型,运用牛顿迭代原理求解出滚子的变形量,进而求得不同滚子在3种数学模型下的接触变形与接触载荷,按照从小到大再到小的顺序进行数值排列,得到任意滚子在不同时刻的接触变形及接触载荷的变化范围。与传统计算方法相比,提出的新方法计算生成的程序迅速,不易出现系统崩溃的情况,且计算结果满足传统方法的数值。The traditional calculation of roller contact load and contact deformation includes a number of calculation,which is prone to system collapse.In this research,three equivalent mathematical models are established by using the equivalent substitution method,the deformation of rollers is solved by using the Newton iterative principle,and then the contact deformation and contact load of different rollers under the three mathematical models are obtained.According to the number arrangement from small to large,the change range of contact deformation and contact load of any roller at different times is obtained.Compared with the traditional calculation method,the program generated in this study is fast,not prone to system collapse,and the calculation results meet the numerical value of the traditional method.
