Today, Henan Huanzhong shock absorber manufacturer to share with you the detection methods of shock absorbers:
Shock absorber vibration damping performance is good or bad, to identify through vibration damping test.
Vibration damping test is usually only in the new design of the trial damper, and batch production will not have to test the damper one by one; only the final test can be. But for the particularly important damper, or in the damping test to adjust to achieve the technical requirements of the damper, it is necessary to test one by one. Vibration test on the whole machine, so that the test conditions are the actual working conditions; vibration test can also be carried out in a special vibration test bench, that is, simulate the actual working conditions, artificially create the vibration source, compared with no damper when the difference between the damper and after the installation of the damper, in order to assess the merits of the damper.
According to different circumstances, you can use a variety of excitation methods to artificially create vibration sources, such as the use of eccentric wheel rotation driven by the slider to produce reciprocal displacement excitation, the use of unbalanced rotor generated by centrifugal force excitation, the use of compressed air blowing machine excitation, the use of loudspeaker excitation, the use of electromagnetic induction excitation, or the use of special shaker excitation, and so on. Vibration test parameters to be measured include frequency, amplitude, speed, acceleration, etc., and sometimes also measure the stress or strain of certain parts of the machine.
