A kind of airbag support free boundary simulation control system and control method thereof

Abstract

An airbag support free boundary simulation control system, including a free boundary simulation controller, a displacement sensor, a pressure sensor, and an air circuit console. Send data to the free boundary simulation controller; the gas circuit console is equipped with a main gas supply circuit and a plurality of gas supply branch circuits, and integrates gas circuit switch control and gas circuit proportional control valves on the gas supply branch circuit, and uses The form of signal exchanges data with the free boundary simulation controller; the pressure sensor is arranged on the air supply pipeline supported by the air bag or on the additional air chamber, and sends data to the free boundary simulation controller in the form of signal; the damper is installed When the product is unstable and shakes, at the position where the swing speed is relatively high, one end of the damper is hinged to the fixed bracket, and the other end is hinged to the product transfer tooling.

Description

technical field [0001] The invention belongs to the field of modal tests, in particular to a free boundary simulation controller and a control method thereof. Background technique [0002] At present, the airbag support system can simulate the free-free boundary conditions required in the modal test, provide flexible support for the tested product, and release the six degrees of freedom on the boundary. At present, there are many controllers on the market, but none of them can be directly used for the real-time control of the free boundary simulation of the airbag support system. Therefore, it is necessary to develop a method that can obtain a variety of sensor signals as monitoring or control feedback, and combine the instructions to solve the corresponding The output signal drives the corresponding components in the airbag support system to act. It is especially important that the control strategy of the controller needs to conform to the workflow of the airbag support sy...
