Abstract

The invention provides a simulation device, relates to the technical field of rail equipment testing devices, and aims to optimize the structure of a test bed and realize reproduction of a rail vehicle under various rail disturbance conditions. The simulation device provided by the invention comprises a foundation, a vehicle body, a first simulation system and a second simulation system, wherein the vehicle body is arranged on the foundation in the length direction of the foundation, a pit is formed in the foundation, and the pit extends in the length direction of the foundation; the first simulation system comprises a first simulation assembly and a second simulation assembly, and the first simulation assembly and the second simulation assembly are arranged at the two ends of the foundation respectively and connected with the two ends of the vehicle body respectively; and the second simulation system is arranged in the pit, one end of the second simulation system abuts against the bottom surface of the pit, the other end of the second simulation system is connected with the bottom of the vehicle body, and the second simulation system provides force in the vertical direction, the width direction of the foundation and the length direction of the foundation for the vehicle body.

Description

technical field [0001] The invention relates to the technical field of rail equipment testing devices, in particular to a simulation device. Background technique [0002] With the increase of the train running mileage, the bogie and the rails have different degrees of wear and tear. The vibration and impact of the worn vehicle on the bogie components is becoming more and more serious, which greatly affects the life of the vehicle components. Therefore, it is very necessary to simulate the track disturbance to the rolling stock in the laboratory. [0003] Existing vehicle dynamic performance test benches mainly focus on the dynamic operation of rolling stock, mainly referring to the stability, comfort and safety tests of rolling stock. The rolling test of the frame and the car body at the same time; or a high-frequency impact test, which also simulates the line disturbance by simulating the contact relationship between the wheel and the rail; Perform long-term simulations i...
