    Abstract
  • According to the system dynamics of rigid bodys, the dynamics simulation models of single-vehicle and four-vehicle double-stack container cars under certain loading and running conditions were established by SIMPACK. Based on the evaluating criterias and indexes of railway train running safety, the simulation result was compared with experiment data. The relationship between the height of loaded car's gravity center and the running safety of double-stack container car was analyzed, and the reasonable height of gravity center was presented. Simulation result indicates that lateral wheelset force, wheel unloading rate and derailment coefficient increase with the increase of the height, and derailment coefficient firstly reaches its limit value. The limit value of the height is 2 480 mm under the most unfavorable loading condition.
