Abstract

The invention discloses a vibration test simulator for a levitation sensor of a high-speed maglev train. The vibration test simulator is used for a vibration test on the levitation sensor of the high-speed maglev train and mainly composed of a sensor mounting base (100), damping devices (200), a base (300) and a vibration motor (400). The upper portion of the sensor mounting base is used for mounting of the levitation sensor, and the vibration motor is arranged on the lower portion of the sensor mounting base. The damping devices are arranged between the sensor mounting base and the base and located on the four corners of the sensor mounting base respectively. Each damping device is composed of two independent square casing connection joints at the two ends, a parallel-connection square casing connection joint in the middle and supporting rods supported between the square casing connection joints. While achieving vibration of the levitation sensor, the vibration test simulator adjusts the shock insulating effect through the damping devices to simulate the shaking working conditions of the sensor more finely.

Description

technical field

[0001] The invention relates to the design of the structure of a shock absorption device, in particular to a vibration simulation device used for vibration testing of a suspension sensor of a high-speed maglev train. Background technique

[0002] Maglev trains are divided into two categories: high-speed and low-speed. High-speed trains include TR series from Germany and MLX series from Japan. Low-speed maglev trains include Japan’s HSST series. Various types of prototype vehicles developed by Maglev Center and other units respectively. The maglev train can run off the track. The key component is the suspension frame. As the running part, it plays a role of connecting the upper and lower parts. It not only bears the weight above the empty spring, but also is the carrier of stable suspension and traction. Therefore, the control of the suspension frame determines the stability of the motion of the maglev train.

[0003] The suspension control of the maglev tra...
