VV type rubber anti vibration mounts
The vibration damping performance of the damper should be identified by the vibration damping test. The vibration-damping test is usually carried out only when the damper is newly designed. After the batch production, it is not necessary to test the damper one by one; only the sizing test is required. However, for particularly important dampers, or dampers that must be adjusted in the vibration test to meet the technical requirements, test one by one. The vibration reduction test is better on the whole machine, so the test conditions are the actual working conditions; the vibration reduction test can also be carried out on a special vibration-damping test bench, that is, the actual working conditions are simulated, the vibration source is artificially manufactured, and there is no vibration reduction. The difference between the device and the shock absorber is to evaluate the advantages and disadvantages of the shock absorber. According to different situations, various vibration methods can be used to artificially manufacture the vibration source. For example, the eccentric wheel is used to rotate the slider to generate the reciprocating displacement excitation, and the centrifugal force generated by the unbalanced rotor is excited, and the compressed air blowing member is used for excitation. The vibration is excited by the speaker and excited by electromagnetic induction.
