Hanging type single track vehicle rolling vibration test device

Abstract

The invention discloses a hanging type single track vehicle rolling vibration test device. The hanging type single track vehicle rolling vibration test device comprises a single track vehicle, the single track vehicle comprises a vehicle body and a bogie, the vehicle body is arranged on the bogie through a shock absorber, the bogie is movably arranged in a track beam, a plurality of vertical actuators are symmetrically arranged above the track beam, two symmetric transverse actuators are transversely and separately arranged on the two sides of the track beam, and two longitudinal actuators aresymmetrically and separately arranged at two ends of the track beam. Caterpillar band conveyor belts are arranged on the two sides of the lower surface of the side surfaces of the track beam, a plurality of walking wheels are movably arranged on the caterpillar band conveyor belts of the lower surface of the track beam, and a plurality of guide pulleys are movably arranged on the caterpillar bandconveyor belts of the side surfaces. According to the hanging type single track vehicle rolling vibration test device, through the combination of the actuators in a plurality of directions, meanwhile, shock excitation is carried out on the track beam in the various directions, the operating state of a hanging type single track vehicle is effectively simulated, and the problems that the test device cannot effectively simulate vehicle operating state, cannot simulate test working condition as much as possible, and the cost is higher are solved.

Description

technical field [0001] The invention belongs to the technical field of rolling vibration test devices for rail vehicles, and in particular relates to a rolling vibration test device for suspended monorail vehicles. Background technique [0002] With the development of rail transportation, suspended monorail transportation has become the first choice for small and medium-sized cities to solve traffic congestion problems. Suspended monorail transportation is a new type of rail transportation. With the increase of its operating mileage, the vibration of monorail operation will intensify, the service environment of each component will deteriorate, and the structural problems exposed to bogies and car bodies will gradually increase, especially in monorail transportation. After the required structure is lightened, structural problems will become more prominent. In order to better simulate the service device of monorail vehicles, it is imminent to establish a rolling vibration tes...

AI Technical Summary

Problems solved by technology

[0004] In view of the above shortcomings, the present invention provides a rolling vibration test device for a suspended monorail vehicle, through the combination of actuators in multiple directions, the track beam is excited in all directions at the same time, effectively simulating the vibration of the suspended monorail vehicle. The operating state effectively solves the problem that the test device cannot effectively simulate the operating state of the vehicle, cannot simulate as many test conditions as possible, and has high costs
