WHAT IS SHOCK TEST?

Shock environment is a transient physical accelerating, such as impact, free-fall, kick, earthquake, or explosion.

A shock pulse can be characterized by its peak acceleration, the duration, and the shape of the shock pulse (half sine, post-peak sawtooth, trapezoid, etc.).

There are various shock phenomena in the production, transportation and operation in various industries such as aviation, aerospace, navigation, weapons, and electronics, which have a great negative impact on the quality and reliability of the products. In order to solve this problem, a shock test was produced and developed on this basis. After more than one hundred years of development, the shock test technology has become quite mature, and it also plays an irreplaceable role in national defense and civil industries.

HOW TO PERFORM SHOCK TESTING

There are three ways to do shock testing: 01Explosion method of pyrotechnic device

The advantage of the pyrotechnic product explosion method simulation test technology is that it can produce the most accurate simulation results, and can produce the high acceleration and high frequency range unique to the near-zone explosion shock environment. The main disadvantages are high test cost, poor safety and large dispersion of loading levels.

02Mechanical shock method

The main advantages of shock simulation equipment are relatively low operating costs, good repeatability, and high predictability of loading levels, but they have some limitations in their ability to generate shock spectra.

03Vibration table simulation method

With the development of vibration table control technology, shock testing that simulate low-amplitude complex shock environments have been realized on the vibrating table.

WHY IS SHOCK TESTING SO IMPORTANT?

Shock testing machine is used to measure and determine the impact resistance of products or packaging, and to evaluate the reliability and structural integrity of products in a shock environment. The impact testing equipment system can perform conventional half-sine wave, post-peak sawtooth wave, or square wave shock test to realize the shock energy that the product is subjected to in the actual environment, thereby improving the product or packaging structure.

CME shock/bump test system meet the requirements of MIL-STD-202, MIL-STD-750, MIL-STD-810, MIL-STD-883, IEC68-2-27 and other shock testing machine standards.
