摘　　要：轮重减载率限值影响铁路长大货物车运用需求和技术发展,其评定一直是特种货车领域的重点研究内容。铁路长大货物车通过小半径曲线产生侧移时,轮重减载率有时会超过限值。综述带侧移的铁路长大货物车车辆动力学试验情况,溯源侧移铁路长大货车轮重减载率限值,分析国内外车辆动力学相关标准,提出我国铁路长大货物车轮重减载率限值建议。The wheel weight reduction rate limit value affects the application demand and technical development of railway,and its evaluation has always been the key research in the field of special freight cars.When the high-capacity freight car moves sideways through the small radius curve,the wheel weight reduction rate sometimes exceed the limit.The vehicle dynamics test of high-capacity freight cars with lateral movement of railway is summarized,the limit value of weight loss rate of high-capacity freight wheels tracing to the lateral movement of railway is analyzed,the relevant standards of vehicle dynamics home and abroad are analyzed,and suggestions for the limit value of weight loss rate of high-capocity freight cars in China are raised.
