Air bag support free boundary simulation control system and control method thereof

Abstract

An air bag support free boundary simulation control system comprises a free boundary simulation controller, a displacement sensor, a pressure sensor and an air path console. The displacement sensor isarranged near an air bag support for lifting a tested product and sends data to the free boundary simulation controller in a signal form; the gas circuit console is internally provided with a gas supply main path and a plurality of gas supply branches, wherein gas circuit switch control and gas circuit proportional control valves are integrated on the gas supply branches, and data exchange with the free boundary simulation controller is carried out in a signal form; the pressure sensor is arranged on an air supply pipeline or an additional air chamber of the air bag support, and sends data tothe free boundary simulation controller in a signal form; and a damper is installed at the position where the swing speed is high when the product is unstable and shakes, wherein one end of the damper is hinged to the fixing support, and the other end of the damper is hinged to the product switching tool.

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...
