What are the detection methods of shock absorber?
The shock absorption performance of the shock absorber shall be verified by the shock absorption test. The vibration reduction experiment usually stops only when the shock absorber is newly designed and manufactured, and it is not necessary to stop the experiment on the shock absorber one by one after mass consumption; Just stop the typing experiment. However, for particularly important shock absorbers, or shock absorbers that need to stop conditioning in the shock absorption test before reaching the technical request, they should be tested one by one. It is better to stop the vibration reduction experiment on the whole machine, so the experimental condition is the practical working condition; The vibration reduction experiment can also be stopped on a special vibration reduction test bench, that is, to imitate the practical working conditions, artificially manufacture the vibration source, and compare the difference between the shock absorber without it and the shock absorber installed, so as to evaluate the advantages and disadvantages of the shock absorber.
According to different conditions, vibration sources can be manufactured by various excitation offices, such as the reciprocating displacement excitation generated by the eccentric rotating to drive the slider, the centripetal force excitation generated by the unbalanced rotor, the compressed air blower, the loudspeaker, the electromagnetic induction, or the special vibration table, etc. The parameters to be measured during vibration test include frequency, amplitude, velocity, acceleration, etc., and sometimes the stress or strain of some parts of the machine. Different industrial departments and different machine products have different requirements for vibration. Dongfeng Company designs different testing methods and selects different testing equipment according to the use of different products, trying to achieve the best quality and valve effect.
