Design and Development of Weight Balance Calculation System for EMUs

动车组的重量均衡计算影响列车的行车安全,该文首先分析了动车组的重量均衡评价指标,研究了常见的Bo-Bo轴式动车组的结构并对车辆建立了三维数学模型,采用刚体力平衡和力矩平衡原理进行静力学分析,推导出车辆重心,轴重及轴重差和轮重及轮重差等的计算公式。其次,基于Visual Studio 2010平台下C#语言和SQL Server 2008数据库开发了一种动车组的重量均衡计算软件,通过对软件计算结果和实测数据对比,验证了软件计算结果的正确性。该软件不仅可实现动车组的重量均衡计算,而且可对所有车辆数据进行统一管理,提高车辆零部件数据的利用率。同时,也对其他类型的轨道车辆的工具开发具有一定参考意义。

The weight balance calculation of the electric multiple units(EMUs)has effects on the train safety.In this paper the weight balance evaluation indexes of the EMUs were analyzed;the structure of the commonly-seen Bo-Bo shaft type EMUs was studied and a three-dimensional mathematical model for the vehicle was established.The rigid force balance principle and the torque balance principle were adopted for static analysis,and the calculation formulas of vehicle gravity center,axle load and axle load difference,wheel weight and wheel weight difference were derived.Then,the weight balance calculation software was developed for the EMUs based on the C#language of the Visual Studio2010platform and the SQL Server2008database.And the correctness of the software calculation results was verified by comparing the calculation results of the software with the measured data.The proposed software can not only realize the weight balance calculation of the EMUs,but also manage all the vehicle data and improve the utilization rate of the data of the vehicle parts.Meanwhile,it will also be of reference for the tool development of other rail vehicles.
