Study on the Relationship between Lateral Offset of the Center of Gravity of Goods C70 Gondola and the Derailment Coefficient

The transverseoffset centerof gravityof goods is one of basic railway technical standards. The current in our country states: The transverseoffset centerof gravityof goods should be less than 100mm.This rule quoting The Soviet Union's 1950s rules is lack of basis. It just meets the derailmentcoefficient in theory. Based on the analysis of vehicle running, the study identified derailmentcoefficient and the transverseoffset centerof gravityof goods. Create the virtual prototypemodel in simulation software, and design appropriate operating condition based on derailmentfactors of influence factors. Built C70 wagon model in SIMPACK simulation platform. Determine the freight loading conditions, tracks conditions and running speed. According to the simulation of experimental data, analysis the relationship between derailmentcoefficient and the transverseoffset centerof gravityof goods. To explore the existing railway freight loading reinforcement on cargo weight the rules allowing lateral offset provisions of modify ability. The transverseoffset centerof gravityof goods.
