Abstract

A new analytical method for calculating the static lateral pressure is introduced to obtain more accurate calculation method of the lateral pressure of end wall and side wall of heavy haul wagon. In the method, the influence of mechanical characteristics of the end wall is considered. For the end wall, a basis for lightweight design can be provided by deducing an analytical method of the lateral pressure which is closer to the experimental results. For the side wall, calculation formula which takes the cycloid curve as projection of rupture surface is derived. The correctness of the formula is verified by comparison with the experimental results. The nonlinear distribution of lateral pressure along the height direction is achieved. Further research is done on the relationship between key parameters of the heavy haul wagon design and the lateral pressure on the side wall.
