A Vibration Test Device for Small Automobile Parts

Abstract

The invention discloses a vibration test device for small parts of an automobile. According to the vibration test device for the small parts of the automobile, the structure is simple, the test process can be kept stable, integrity and trueness in the detection simulation process are high, and the obtained test result is more scientific. The vibration test device for the small parts of the automobile comprises a body, wherein two opposite fixed plates are arranged on the body, a clamping fixing base is arranged on the top of the body, each fixed plate is connected with the outer side face of the clamping fixing base through a transverse spring, a vibration-starting and speed-regulating motor is arranged on the body, a plurality of vertical springs are arranged on the lower portion of the body, at least one vertical spring is provided with a vertical vibration sensor, and at least one transverse spring is provided with a main vibration sensor. The vibration test device for the small parts of the automobile has the advantages that the structure is simple, the total weight is light, resonance in the frequency band is low, influence is low, comprehensiveness and integrity are high when detection is carried out, the simulation degree is high, and the obtained test result is more accurate and more scientific.

Description

Technical field [0001] The invention belongs to the field of automobile parts detection, and in particular relates to a vibration test device for small automobile parts. Background technique [0002] The number of parts and components on the car is very large, and there are many key parts and components, which have a significant impact on the normal use of the car. These parts need to pass a variety of tests, one of which is the vibration test. Vibration test is to simulate various vibration environments encountered by auto parts during assembly and use stages, and to identify whether they can withstand the vibration pressure in the working environment. The purpose of the vibration test is to determine whether the designed and manufactured auto parts can withstand external vibrations or self-generated vibrations during transportation and use without damage, and maintain normal performance and reach a predetermined life. However, the key components of these automobiles are gener...

Problems solved by technology

The disadvantage of this utility model is that if this type of device is used as a test device for the vibration of small automotive parts, it is easy to cause more resonance in the test frequency band due to its large mass during the test process, thereby affecting the quality of parts or test results. , and there are still deficiencies in the comprehensiveness and integrity of the test simulation
