    Abstract
  • Based on the characteristic that two carbodies of articulated container flat vehicle are connected with an articulated connector and a common articulated bogie is used at articulated position, a nonlinear mathematic model of the vehicle was established by using NUCARS dynamics simulation software, the nonlinearities were considered resulted from wheel/rail contact geometry, wheel/rail creep forces, nonlinear suspension characteristics and articulated connector, and its running stability, curve negotiating performance and riding comfortableness were studied by using numerical simulation method. Analysis result shows that the vehicle has enough high hunting critical speed, its curve negotiating performance indices are in the safe range required by GB/T 5599-1985, and the lateral and vertical indices of riding comfortableness are less than 3.5 at the running speed range of 120 km·h-1, so the vehicle has eximious dynamics performance, and meets the running requirement at 120 km·h-1.
