摘　　要：针对斜楔式货车转向架减振器结构复杂、减振性能不稳定的特点,在保持三大件式转向架特性的前提下,提出了杠杆式减振装置重载货车转向架的结构方案。对减振装置的结构原理进行了详细论证,并根据TB/T 1335-1996和TB/T 1959-2006标准,通过有限元法对侧架、摇枕进行了强度分析。结果表明,侧架、摇枕的静强度与刚度均满足标准要求。Due to the characteristics of complex structure and unstable damping performance of the wedge-type damper,a new lever-type friction damper is proposed,and the structure of corresponding heavy haul freight bogie is designed,without changing advantages of traditional three-piece bogie.The structure and theory of the lever-type damper are provided in detail.According to TB/T 1335-1996 and TB/T 1959-2006,the stress analysis of side frame and bolster of new bogie is conducted by FEM,and the results show that the static stress and stiffness of side frame and bolster can meet the relevant standard requirements.
