铁路不规则非匀质货物重心计算方法

A Calculation Method for Barycenter of Railway Irregular and Inhomogeneous Freight

为了计算铁路不规则非匀质货物的重心位置,保证铁路货物装载的合理性和运输的安全性,在分析重心计算研究现状的基础上,基于力矩平衡原理,采用三支点倾斜测力法,给出铁路不规则非匀质货物重心位置的计算方法。通过二维平面得到货物重心在水平面上的坐标公式,利用重心在倾斜平面和水平面的垂直投影以及重心铅垂线与倾斜平面的交点构造出两个相似三角形,从而通过三维空间得到货物重心在垂直方向上的坐标公式,为铁路货物重心位置的确定提供了理论依据。

To calculate the barycenter of irregular and inhomogeneous railway freight and ensure the rationality of the loading of railway freight as well as the safety of transportation, this paper analyzes the research status of barycenter calculation. Based on the moment balance and the three-pivot tilting measurement method. A method for calculating the location of the barycenter of irregular and inhomogeneous railway freight is given. The coordinate formula of the freight barycenter on the horizontal plane is obtained through twodimensional plane. Two similar triangles are identified based on the vertical projection of the barycenter on the inclined plane and the horizontal plane, and the intersection point between the vertical of the barycenter and the inclined plane. The coordinate formula of the freight barycenter in vertical direction is obtained through three-dimensional space. This paper provides theoretical basis for calculating the location of railway freight barycenter.
