Description

Shock absorber test device

[ technical field ] A method for producing a semiconductor device

The utility model relates to a bumper shock absorber technical field, in particular to bumper shock absorber test device.

[ background of the invention ]

The purpose of bumper shock absorber is for the damping, and the bumper shock absorber is equipped with in most products is for reducing the vibration transmission of vibration basis to the product, reaches the effect of protection product. The shock absorber is mainly used for restraining the shock generated when the spring absorbs the shock and rebounds and the impact from the road surface, and is widely applied to vehicles such as automobiles and the like to accelerate the attenuation of the vibration of a frame and a vehicle body so as to improve the driving smoothness of the automobile. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping.

The quality of the vibration damping performance of the vibration damper is determined by a vibration damping test. At present, the performance of the shock absorber is verified mainly in two aspects, wherein in one aspect, a bench test is carried out; and secondly, carrying out whole vehicle strength verification on a cobble road section of a test field. During the bench test, the vibration damping test can be carried out on a special vibration damping platform, namely, the actual working condition is simulated, the vibration source is artificially manufactured, and the difference between the condition without the vibration damper and the condition after the vibration damper is installed is compared to evaluate the quality of the vibration damper. The vibration source can be artificially produced by various vibration excitation methods according to different conditions, such as vibration excitation by reciprocating displacement of a slide block driven by the rotation of an eccentric wheel, vibration excitation by centrifugal force generated by an unbalanced rotor, vibration excitation by a compressed air blowing machine, vibration excitation by a loudspeaker, vibration excitation by electromagnetic induction, or vibration excitation by a special vibration table.

In the test process of using a special vibration table, a plurality of wrong installation modes of directly pressing the upper surface of a product by a pressing strip to fix appear. The installation mode is too tight, and the shock absorber has no damping effect completely; when the pressure is too loose, the surface of the product collides with the pressure strip and the table body due to the existence of the shock absorber in the vibration process, so that damage is caused. It is clear that the samples failed to withstand the specified test conditions. The bottom of the shock absorber is installed when the common product is actually used, so the test installation mode is not suitable for the product with the shock absorber.
