项目名称:机车车辆一轨道耦合动力学理论体系及工程应用项目批准号:59525511,50178061,50475111 项目负责人:翟婉明项目完成单位:西南交通大学中国铁路长期处于超负荷运输状态,其基本特征是客货共线,客运提速和货运重载。这种超负荷运输方式在有效提高运能的同时,也严重加剧了机车车辆与线路的动态相互作用,带来了较常规铁路更为突出的轮轨动态安全问题。传统的车辆动力学、轨道动力学理论体系,将机车车辆和铁路轨道分离成两个相对独立的子系统分别加以研究的方法, 已不能解决这种复杂的动态相互作用问题。西南交通大学以翟婉明教授为首的课题组在国家自然科学基金持续资助下,对这一重大工程科学问题进行了10多年的研究,取得了系统性研究成果。
Project Name: Theoretical System of Orbital Coupling Dynamics of Rolling Stock and Engineering Application No. 59525511, 50178061, 50475111 Project Leader: Zhai Wanming Project Completion Unit: Southwest Jiaotong University China Railway has been in a state of overload traffic for a long time. Its basic characteristics are: Cargo collinear, passenger speed and freight overloaded. This kind of overload transportation mode effectively aggravates the dynamic interaction between locomotives and trains, and brings about more prominent problems of wheel-rail dynamic safety than conventional railways. The traditional theory of vehicle dynamics and orbital dynamics, and the separation of rolling stock and railway tracks into two independent subsystems, respectively, have failed to solve this complex dynamic interaction problem. Under the continuous funding of the National Natural Science Foundation, the research group led by Professor Zhai Wanming of Southwest Jiaotong University conducted a research on this major engineering science for over 10 years and achieved systematic research results.
