摘　　要：天津地铁选配车辆轴箱轴承时,根据测量得到的轮轴轴颈的实际尺寸来选配符合公差要求的轴承。由于有很多组轴承可供选配,所以选配过程非常耗时,且很难选配出符合配合公差的最优轴承组。通过分析选配轴承的过程,提出了用MATLAB GUI编程来自动选取轴承,并基于靠近公差带中间值为最优解的原则自动选配最合适的轴承。与人工选配相比,该方法简单明了,计算速度快。最后,用两组计算实例验证了计算机求解结果的正确性。In Tianjin Metro, when selecting vehicle axle box beating, the actual size of shaft neck is used to match with bearings conforming tolerance requirements. As there are lots of groups of bearings available for the selection, the selecting process is often time-consuming and it is difficult to get the optimal bearing which matches with the fit tolerance. One method that using the MATLAB GUI programming to automatically select and get the optimal bearing and match with the most optimal bearing with the principle of closing to intermediate value of the tolerance zone was proposed. Compared with manual selection and matching, this method is simpler and clearer, and the computing speed is faster. Finally, two groups of calculating examples were given to verify the correctness of the method.
