Abstract
The balance equation of bulk goods under different conditions which take cycloid as the rupture surface ' s model firstly was built. Then the academic dynamic lateral pressure on side and end walls by bulk goods was calculated through numerical method. Through the analysis of calculated results and the research productions at home and abroad, a dynamic lateral pressure equation which is fit for railway bulk wagon is given. When longitude impact acceleration is less than 0. 8g, the vertical vibrating is the main factor of dynamic lateral pressure. With the increase of vertical vibrating acceleration and the load height, the dynamic lateral pressure of end and side walls increases in quadratic. While the acceleration surpasses 0. 8g, the longitude impact becomes the main factor which affects the dynamic lateral pressure on end wall. On the base of passive soil pressure, the dynamic pressure on the end increases with quadratic time of the impact acceleration, but the dynamic pressure on side wall remains the value of that endured at the acceleration of 0.8g. After checking and comparing, this equation is reasonable and applied,so it can be seen as a reference to the design of bulk goods vehicle.关键词
