Method for testing composite damper

Abstract

The invention is about the testing method of a combined damper which simulates the using state of the combined damper by a testing device. It gets the transmission ratio and the frequency of the experiment process, the phase margin in the different vibration frequency and the gravitational acceleration. Then it applies the data into the deduced mathematic formula to compute the needed spring coefficient and the damping coefficient, so it can provides the reference of selecting the proper combined damper to the production or using manufacturer.

Description

technical field [0001] The invention relates to a testing method for a composite damper, in particular to a testing method which can best simulate the actual use state, and then obtain the best testing result. Background technique [0002] Figure 1A with Figure 1B As shown, it is a perspective view and a cross-sectional view of a new hybrid damper 1 (Hybrid Damper). The sealing material of the top 11 is soft silicone (or other elastic materials), and the inside is filled with a suitable damping fluid 12. The center position is formed as a covering part 13 of a pin, which is inserted into the pin of the machine to be shock-absorbing or shock-absorbing, and is mainly used for the shock-absorbing function of a car media player, such as a CD player or a DVD player etc., to prevent jumping stitches or machine crashes. However, due to the difference in the amount or quality of the internal damping fluid, the shock absorption effect will be affected at the same time. However, t...

Problems solved by technology

[0003] 1. Although the actual machine test is not difficult, due to the cumbersome setup of the experiment and the long time required for the test, and without prior screening, many composite dampers provided by many manufacturers are tested, not only Time-consuming and labor-intensive, the efficiency is not obvious;

[0004] 2. As far as the supplier of the composite damper is concerned, it is impossible to quickly determine whether the finished product meets the manufacturer's requirements. It may provide dozens of products with different specifications, and only one of them has passed the manufacturer's verification, which is a waste of cost and time consuming;

[0005] 3. As far as manufacturers of media players are concerned, they must go through multiple tests each time to select a better product, which is time-consuming and troublesome. The development time for new models cannot be effectively shortened
