General shock absorber dynamic and static test bench

Abstract

The general shock absorber dynamic and static test bench relates to a kind of vibration experiment test equipment, which includes a mechanical system and a test system, and the test system includes a vibrator, a signal generator, a power amplifier, a force sensor, a photoelectric displacement sensor, an acceleration sensor, Acquisition card and processor; the mechanical system includes an upper base, an adjusting screw, a rotating shaft, an L-shaped plate, a vibrator base, six columns, a lower base, a T-shaped shaft and an inertia swing bar. The beneficial effects of the present invention are: the mechanical system of the test bench has simple structure and reliable performance, combined with the test system, the test bench can independently complete the vertical and transverse dynamic and static performance tests of the shock absorber, and realize the multi-degree-of-freedom test function , strong versatility and wide applicability.

Description

technical field [0001] The invention relates to a vibration experiment testing device, in particular to a test bench for dynamic and static performance testing of various shock absorbers or vibration isolators. Background technique [0002] With the development of industrial modernization, whether it is vehicle equipment, processing equipment or ship equipment, there are higher requirements for vibration and noise. The shock absorber or vibration isolator is an important component of vibration and noise control, and its vibration isolation effect is good. Vibration is the main factor to measure the performance of the vibration isolator. Therefore, the performance test of the vibration isolator is particularly important. Most of the existing shock absorber test platforms are special-purpose test devices, which are mainly made for a certain type of shock absorber, and can only complete the performance test under a single degree of freedom, which is not universal. Therefore, ...
