【Abstract】 This article establishes a dynamic simulation model of a triple united articulated flat vehicle using SIMPACK software, and builds twisted line based on the twisted shape parameters specified in the AS standard for simulation calculation. The safety performance of the triple united articulated flat vehicle when passing through the twisted line is analyzed. The results indicate that the maximum load reduction of the evaluated wheels meets the requirements and can safely pass through the twisted line specified in the standard.更多还原
