摘要
介绍了国外重载货车典型转向架的技术特点和相应的技术措施,回顾了我国货车转向架的发展历程以及成熟的关键技术,总结了我国铁路货车转向架的技术现状。针对发展我国大轴重货车转向架的轴重、速度、车轮直径、设计原则和评价准则进行了讨论,并阐述了研发大轴重货车转向架应当关注的噪声、径向性能、模态及轮轨磨耗动态分析等研究热点问题。
The technical features and corresponding technical measures of typical types of heavy haul freight car bogies abroad are described.The development history and mature key technologies of freight car bogies are reviewed.The present technical conditions of railway freight car bogies in our country are summarized.Discussion is made on axle load,speed,wheel diameter,design principle and evaluation code in developing freight car bogies with big axle load in our country,and such hot spots in research as the noise,radial performance,modal conditions and dynamic analysis of wheel-rail wear to which attention should be paid in development of freight car bogies with big axle load are expounded.
