Actuator position optimization method, system and device and vibration test bench

Abstract

The invention discloses an actuator position optimization method, system and device and a vibration test bench, and relates to the field of train tests.In the scheme, all vertical positions and all transverse positions meeting preset conditions are combined to obtain a plurality of combined positions; the N vertical actuators and the M transverse actuators are arranged at corresponding positions in the combined positions, each combined position is subjected to a test, the loading force of each actuator calculated in each test and an analysis result are compared with a simulation result, and a simulation result is obtained. A combined position where the loading force of M transverse actuators is uniform, the loading force of N vertical actuators is uniform and the difference between an analysis result and a simulation structure is small can be selected as an optimal position, the combined position is correspondingly arranged on the optimal position, the test accuracy is ensured, and meanwhile, the loading force is relatively uniform, so that the test efficiency is improved. The deformation or damage of the vehicle body caused by overlarge loading force of a certain actuator can be avoided, and the safety and reliability of the test are ensured.

Description

technical field [0001] The invention relates to the field of train testing, in particular to an actuator position optimization method, system, device and vibration test bench. Background technique [0002] In order to ensure the safety and comfort of the maglev train during operation, it is currently necessary to simulate the vibration state of the maglev train during operation through a vibration test bench. Do a simulation. Among them, the position of the actuator is very critical. If the position of the actuator is not suitable, it may cause the force of the vehicle body to be unconcentrated or uneven, resulting in deformation or structural damage of the vehicle body. [0003] Therefore, it is an urgent problem to provide an optimization method for the position of the actuator to avoid deformation or damage of the vehicle body. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an actuator position optimization method, system, device ...
