Spoiler Three Comprehensive Vibration Test

Spoiler three comprehensive vibration test test

Overview of the 3. Comprehensive vibration test:

The three comprehensive vibration test is a comprehensive test of temperature + humidity + vibration three environmental stresses applied at the same time, the role of the comprehensive environment can more realistically and more realistically reflect the performance of the product in field use, and more expose the defects of the product.

Applying separate environmental stresses to the product can trigger product failure, and then applying three different environmental stresses to the product can easily get a 3-5 times acceleration effect. At the same time, by combining different environmental stresses, it is possible to stimulate faults that cannot occur when individual stresses are applied.

In the comprehensive test of temperature, humidity, and vibration applied at the same time, from the mechanism of failure, the inside of the product undergoing temperature cycling expands and expands due to the difference in the expansion coefficient of the material, and loosens at the joint, and if humidity is applied, moisture will invade from the gap, reducing the friction coefficient of the joint and the joint. Vibration stress is applied and the resonance of the product will occur relative to a specific frequency. Through repeated processes of motion, moisture absorption, freezing, and resonance, new failure modes (caused by greatly accelerated individual factor failure modes and the combined effect of three factors) are made possible.

3. Comprehensive vibration detection range

Temperature and humidity and vibration three comprehensive vibration test is widely used in aviation, aerospace, military, electrical, electronic and other products and parts. Third, comprehensive testing is an indispensable and important test means for the whole process of product and material development, prototype test and product qualification test.

3. Comprehensive vibration detection standards

Three comprehensive vibration test standard reference: GB/T2423.35, GB/T2423.36, IEC/EN60068-2-50; IEC/EN60068-2-51.
