Problems solved by technology

This process needs to be done many times in one test, and different parameter tests need to be adjusted, so a complete test takes a long time
At the same time, the linear performance of the existing vibration test equipment is poor, and there is a large distortion in the test, which affects the results of the simulation test
Although in recent years, vibration test equipment that uses electrical control to adjust has appeared, but its performance and convenience of adjustment still cannot achieve satisfactory results.

Embodiment Construction

[0013] Such as figure 1 As shown, the four rotary cylinders 2 are connected to the transmission device through four flexible couplings 3; the shaft one 4 and the hand wheel one 6, the shaft two 5 and the hand wheel two 7, the shaft two connected on the flexible coupling 3 Four 13 and hand wheel three, shaft four 13 and drive shaft 32 are connected through gearbox 10; adjusting hand wheel one, hand wheel two, and hand wheel three can set the initial phases of four rotary cylinders 2, when the motor 9 passes through the V-belt 8. When the driving shaft 32 is driven, the eccentric mass of the rotary cylinder 2 rotates to generate a centrifugal force. At this time, the vibration direction is synthesized according to the set phase to form a sinusoidally changing exciting force, so that the table 20 and the test product installed on the table 20 press Vibration is generated in a certain direction. Setting the phase can make the vibrating direction of the table top 20 vibrate in ver...

Abstract

The present invention relates to a mechanical structure antivibration property simulation testing platform system. Said system includes platform supporting mechanism formed from four air spring supporting mechanisms, vibration exciting mechanism formed from four rotary oil cylinders and pilot-controlled non-return valves, hydraulic control mechanism, flexible couplers and driving device. Said invention also provides the concrete structure of the above-mentioned every component, and provides their connection mode.

Description

Technical field: [0001] The invention relates to a simulation test platform system, in particular to a simulation test platform system for the anti-vibration performance of a mechanical structure. Background technique: [0002] The product undergoes various vibration simulation tests through simulation tests to meet the vibration test requirements when the product leaves the factory. Vibration test is an important task for manufacturers to ensure product quality. It generally involves testing the following parameters: vibration frequency, vibration displacement, speed, acceleration, etc. Existing vibration test equipment mostly adopts mechanical setting methods. For example, in the vibration simulation test, when the vertical vibration or horizontal vibration is set by mechanical means, and when the vibration parameters need to be modified, it needs to be readjusted. Frequency or amount of vibration. This process needs to be done many times in one test, and different param...
