Tri-axial and six-degree-of-freedom vibration test device

Abstract

The invention discloses a tri-axial and six-degree-of-freedom vibration test device. The device comprises a MIMO controller, a power amplifier system, a vibration platform, a vapor system and a hydraulic system; the MIMO controller generates a driving voltage signal, and then inputs the driving voltage signal into the vibration platform through the power amplifier system, and meanwhile, the response on a vibration plane is fed back to the MIMO controller; the vapor system is connected with the vibration platform, the hydraulic system is connected with the vibration platform, and the vibration platform comprises electric vibration tables, hydrostatic pressure bearings, a vibration board, trunnion brackets, a base and a ball hinge over-displacement protection device; the electric vibration tables are connected with the base through the corresponding trunnion brackets; and the electric vibration tables are connected with the vibration board through the hydrostatic pressure bearings; the electric vibration tables are connected to lower surface of the vibration board and various laterals of the vibration board through the hydrostatic pressure bearings; and the vibration board is connected with the base through the ball hinge over-displacement protection device and an auxiliary support device.

Description

technical field [0001] The present invention relates to the technical field of vibration test, and more specifically, the present invention relates to a three-axis six-degree-of-freedom vibration test device. Background technique [0002] What high-performance weapons and equipment in the prior art actually experience is a multi-degree-of-freedom vibration environment. With the update of weapons and equipment, the corresponding real simulated vibration environment is more diversified. In order to more realistically simulate the real vibration environment faced by high-performance weapons and equipment, the independent research and development of vibration tests has become an important development trend. When simulating the real vibration environment faced by high-performance weapons and equipment, the test process requires more complex, more technically difficult, and there will be more elements to control, so the requirements for test equipment and test programs are higher...

Problems solved by technology

[0003] At present, there is no better device of this kind in China, especially the test device with large thrust and wide operating frequency range

At the same time, with regard to the test method of this type of vibration test device, the corresponding domestic standards only give the relevant principles, lack of a clear multi-point excitation vibration test method, and cannot be used to guide the three-axis six-degree-of-freedom vibration test of the equipment
