Power machinery closed loop face-to-face double gear case inclination type excitation test stand

Abstract

The invention relates to a power machinery closed loop face-to-face double gear case inclination type excitation test stand. The power machinery closed loop face-to-face double gear case inclination type excitation test stand comprises a transverse gear case excitation device, a power machinery closed loop face-to-face double gear case inclination type test stand, a portal frame vertical excitation device, a vibration isolation T-shaped groove cast iron base platform, a vibration isolation concrete base and a vibration isolation spring group system arranged at a lower end of the vibration isolation concrete base. Through cycle use of the power in a closed loop system, energy consumption is reduced, tests can be maintained through utilizing a motor with small power to compensate a part of the power, so the energy saving purpose is realized; the test stand is an inclination type test stand, so the gear cases are enabled to generate certain inclination angles transversely and vertically, lubrication oil distribution and the lubrication situation of the gear cases can be simulated and detected when a high speed train is under conditions of curvilinear motion, braking and acceleration, through the test stand, safety operation of a high speed train group is improved, travelling comfortableness of a high speed motor train unit is improved, and development of the motor train unit technology is greatly facilitated.

Description

technical field [0001] The invention relates to a test platform for detecting parameters of a rail vehicle transmission system, in particular to a power machinery closed-loop face-to-face double gear box side-tilt excitation test platform. Background technique [0002] At present, the development of high-speed train technology in my country is advancing by leaps and bounds. The maximum operating speed of the new generation of EMUs has reached 380km / h, and the maximum test speed of the newly developed EMUs is close to 600km / h. The increase of train speed and vehicle axle load has aggravated the impact vibration between the wheel set and the track, and the ride comfort, safety and stability of rail vehicles have become increasingly prominent. As an important part of the rail vehicle bogie, the gearbox is responsible for transmitting the power of the train to the wheelset, and its performance directly affects the performance of the bogie and even the entire train. The working ...

Problems solved by technology

Most of the existing gearbox test benches are tested in an open-loop state, which not only needs to provide a large external power, but also causes waste of energy during the test process
