Abstract

Permitted height of combined center of gravity for railroad cars in China is studied. This study establishes a MBS model of the railroad freight car, and then validates the model. Orthogonal experiment method is used to find the worst operating condition. The factors’ levels are determined and used for designing orthogonal experiment schemes. Extensive simulations are performed for the schemes. Statistics analysis is applied to simulation results. The worst operating conditions for Grade I and III railroad are derived from objective analysis. Based on the worst operating conditions, the permitted height of combined center of gravity for railroad cars can be increased to 2500mm. The influence degree of each factor is derived by variance analysis. Factor B is a significant factor for derailment coefficient, factor A and factor C have little effect on derailment coefficient. But the three factors are significant factors for wheel unloading rate.
