Jigging platform three-way excitation platform connecting mechanism

Abstract

A connecting mechanism of vibration table three-directional shocking platform comprises force a passing mechanism which enable the platform for placing sample connect the vibration table at lateral side adjacent to the platform and bottom side of the platform respectively. Said force passing mechanism comprises a sliding block and a horizontal sliding track and a vertical sliding track which are respectively connected to the upper and lower end surfaces of the sliding block. Said connecting mechanism of vibration table three-directional shocking platform has rational design, low making and maintaining cost, and can satisfy the experimental request for achieving simultaneous vibration three-axially by using the three-directional shocking platform. And the connecting mechanism is able to achieving restoration of actual vibration environment furthest, which has light weight, small volume and be easy to assemble and maintain and manage. The mechanism is able to simplify the device of the entire simultaneous shocking apparatus three-axially, and the mechanism does not generate producing source such as public hazard noise and so on.

Description

technical field [0001] The invention belongs to the technical field of vibration test equipment capable of providing multi-directional excitation, and in particular relates to a three-directional excitation platform connection mechanism of a vibration table capable of providing three-axis simultaneous excitation to the same platform. Background technique [0002] In the field of manufacturing and testing, in order to test whether the products and buildings have the original performance when encountering the actual vibration environment, such as the vibration of vehicles running on uneven ground, the vibration of aircraft in atmospheric turbulence, and the vibration of large machinery on the ground Or buildings affected by earthquakes, and random vibrations generated by processing machinery when encountering soft and hard objects or irregular heights. It is necessary to simulate the above-mentioned vibration environments such as earthquake waveforms and road conditions for tr...

AI Technical Summary

Problems solved by technology

Since the above-mentioned vibration environment is multi-axial random vibration, the existing uniaxial vibrator cannot realize the vibration simulation of three axes at the same time

Simultaneous vibration of the three axes needs to install single-degree-of-freedom vibrators on the three axes respectively, and the known mechanical connection device connecting the vibrating table surface and the single-degree-of-freedom vibrator is easy to cause the difference between the three single-degree-of-freedom vibrators. There is a strong motion cross-coupling between the vibration table itself and the degree of freedom of motion in the non-force transmission direction to produce lateral limit constraints

Using the above-mentioned vibration test equipment and test method will inevitably increase the test time. At the same time, the vibration test method can not restore the actual vibration environment poorly, and cannot truly reproduce the real vibration environment.
