摘　　要：提出了一种轴承的虚拟可靠性试验方法。建立轴承三维虚拟试验样机,利用ADAMS参数化技术以及编写伪随机数子程序等方法对试验样机进行Monte Carlo参数化,利用自定义函数模拟轴承各类参数的随机误差,对参数化的轴承样机进行多次虚拟试验,获取试验数据。利用VC++编程自动读取试验结果文件并求取轴承内圈跳动的可靠度,分析了各类随机误差对轴承动态特性的影响。开发了通用的轴承虚拟可靠性试验程序。Three-dimensional virtual test prototype of the bearings was set up in ADAMS firstly,Monte Carlo parameterization of the prototype was carried out in pseudo-random numbers subroutine.After times of virtual test on the parameterize prototype,analogizing different bearing parameter＇s random errors with self-defining function,experimental data were got.Introducing VC＋ ＋ program to read the data file automatically to compute the run-out reliability level of the bearing＇s inner race,it presents a method of virtual reliability test for bearing,which can analyze the effects of different random errors on bearing dynamic behavior effectively.Lastly,it developed an universal bearing virtual reliability test program.
