对如下可靠性问题进行仿真 现在有两种方案：方案一是损坏一个更换一个；方案二是一旦有轴承损坏就全部更换．试通过计算机仿真对这两种方案做出评价．(The following issues on the reliability of simulation now there are two programs: a program to replace a damaged one program Second, once all the replacement of damaged bearings. Examination by computer simulation to assess the two programs.)
