阐释了高速铁路联调联试的内涵和必要性,结合我国高速铁路联调联试的工程实践,从轮轨关系、弓网关系、列车空气动力学、车-线-桥耦合等角度,对高速铁路联调联试关键技术进行了分析,对高速铁路联调联试和试验研究取得的主要成果进行了系统性提炼和归纳,给出可供高速铁路建设和运用参考的相关思考和建议。
The paper summarizes start, growth, accumulation, development,improvement, and leadership of the research on aerodynamics of high-speed rails in China, which focuses on train aerodynamics, vehicle-track-bridge-tunnel coupling aerodynamics, vehicle-wind-sand-rain-snow environmental aerodynamics, pantograph-catenary aerodynamic and body aerodynamics. It is devoted to finding the mechanism of formation, building fundamental theorem, creating technical breakthrough, proposing measures to tackle aero dynamical problems which pose a threat to development of high-speed railways and safety of operation, and realizing their engineering application. The paper introduces a series of experimental platforms for testing aerodynamics of high-speed rails and novel experiments we have accomplished, including moving vehicle model tests, human comfort/vehicle body stiffness/air tightness tests under alternating pressure, aero dynamical experiments in wind/sand/rain/snow coupling environment, vision inspection systems, experimental platform for full-scale vehicles, private/public wind tunnel and high-availability clusters for numerical simulation. Finally it discussed the ongoing research and our thoughts about further development.
