Medium and low speed magnetic levitation vehicle suspension frame strength testbed

Abstract

The invention discloses a medium and low speed magnetic levitation vehicle suspension frame strength testbed. The testbed comprises a bearing bracket, a bearing bracket fixed beam, a vertical load bearing bream, a horizontal load bearing frame, a T-shaped slot platform, a foundation, an actuator, a displacement constraint module and a suspension frame tool connected to a suspension frame; the bearing bracket fixed beam comprises a first fixed beam and a second fixed beam; the suspension frame tool comprises an electromagnet replacement tool and an air spring sliding table replacement tool convenient for performing loading on the suspension frame by the actuator; the testbed can simulate the stress working condition of an unilateral module of the suspension frame under a real environment and analyze the loading condition of the actual magnetic levitation vehicle; the necessary working conditions in the actual running process of multiple medium and low-speed magnetic levitation vehicle capable of loading the lateral load and the longitudinal load can be simulated, the synchronous or asynchronous loading is realized, thereby performing strength test on the suspension frame in a relatively comprehensive way.

Description

technical field [0001] The invention relates to the technical field of maglev train testing, in particular to a suspension frame strength test bench for medium and low-speed maglev vehicles. Background technique [0002] As the main component of the running mechanism of the maglev vehicle, the suspension frame is of great importance. The failure of the suspension frame will directly threaten the driving safety of the maglev vehicle. To balance safety and efficiency, it is necessary to determine the static strength of the structure and its fatigue life in order to arrange a reasonable maintenance period. At present, there is basically no good solution for the strength test and method of the suspension frame of the maglev vehicle. Usually, the simulation analysis is used to evaluate the strength and life of the rolling stock bogie according to the test analysis method of the rolling stock. Due to the rapid development of maglev vehicles, especially for the development of urba...

Problems solved by technology

[0003] For the urban operation of medium and low-speed maglev trains, due to the complexity of the operating lines and the environment, the various loads on the running mechanism in the actual operation process are complicated and the frequency is high, and there are many people in operation. The test is put into use, and its safety hazard is huge
