متن کاملBifurcation Analysis of High-Speed Railway Vehicle in a Curve
In order to prevent unpleasant incidents, preservation high-speed railway vehicle stability has vital importance. For this purpose, railway vehicle is modeled using a 38-DOF. This paper presents an investigation on limit cycle and bifurcation of high speed railway behavior. It is revealed that the critical hunting speed decreases by increasing the wheel conicity. Also the critical hunting speed...
متن کاملStrength Analysis and Experiment of High Speed Railway Gearbox Bracket
Light-weighting of high speed railway equipments has become a major trend, which leads the upgrades of equipments. A new C-shaped bracket has been produced to connect the driving gearbox with the bogie. This paper built a three-dimensions model of a C-shaped bracket, got the maximum and distribution of the stress and deformation under two different working conditions form finite element analysi...
متن کاملLateral Stability Analysis of High-Speed Railway Vehicle on Curve
A vehicle body, two bogie frames and two wheelsets for each bogie frame are used to describe the railway vehicle model. The system dynamic is modeled using a 38-DOF system including the longitudinal, lateral, vertical, roll, pitch and yaw displacements. A heuristic nonlinear creep model and the elastic rail are used to simulate the wheel-rail contact. Stable movement and the corresponding limit...
متن کاملDynamic analysis of high speed railway bridge under articulated trains
The problem of vehicle–bridge dynamic interaction system under articulated high speed trains is studied in this paper. A dynamic interaction model of the bridge-articulated train system is established, which is composed of an articulated vehicle element model and a finite element bridge model. The vehicle model is established according to the structure and suspending properties of the articulat...
