Abstract:The sub-project 6 initially establishes the analysis method of high speed trains performance considering the relationship of wheel-rail, fluid-solid and catenary-pantograph, including such aspects: (1) nonlinear stability and smoothness analysis method of high speed train based on the wheel-rail relationship; (2) establish the traction drive model of high speed train, analyzes the influence of catenary-pantograph relationship to the traction and braking performance; (3) analyzes the influence of adhesion control on the braking distance; (4) research on the noise resource of high speed train and noise reduction method. Based on this, the report analyzes the relationship between various factors and operating performance of high speed train, which is prepared for the establishing of evaluation method and design principles of high speed train.
Key Words:High speed train;Running stability;Running smoothness;Traction and braking performance;Comfort
