【摘要】 从轮轨动力作用的角度，对三大件式、整体构架式、自导向式和迫导向式４种典型货车转向架的性能作了评述。在此基础上，提出一种适应我国线路的低动力作用重载货车转向架的发展模式，并借助于理论计算对其动力学性能作了预测。更多还原

【Abstract】 From the point of view of wheel/rail dynamic interactions,the performance advanteges and shortcomings of four typical freight car bogies,which are three-piece bogie,frame type bogie,self-steering bogie and forced-steering bogie,are compared.A lower dynamic force bogie configuration for heavy-haul freight car is given in this paper, and its dynamic performance has been investigated through computer simulations.更多还原
