货车无轴箱滚动轴承段修微机管理系统

Discussion about evaluation criteria of strength and stiffness of passenger carbody in our country

本文简要介绍了铁路货车段修无轴箱滚动轴承微机管理系统的组成和应用情况。该系统利用微机对货车轴承进行统计管理,可及时提供轴承的各种重要信息,提高工作效率。

Several stipulatious concerning evaluation ofstrength and stiffness of passenger carbody has been themain limiting factors in reducing weight of passengercarbody steel structure. In this paper. the form incombinling stress, method of stress calculation, selec-tion of allowable stress of material and evaluationvalue of carbody stiffness etc. in stress evaluation areinitially analysed and discussed, and respective impro-vement suggestions are put forward.
