The Application Of Shock Test
Products are inevitably affected by impact, bump, free fall, tumbling, etc. During production, transportation, loading and unloading as well as during the use of the products. All of these are transient excitation on the object, causing the object to produce mechanical characteristics of high speed, acceleration,strain rate, etc instantly. These kind of characteristics are completely different from that in static load, and may cause problems to the object in terms of structural strength and stability and sometimes the object may fail. Therefore, it is necessary to study the effect of impact and reproduce the shock environment, to assess the structural strength and performance of the object under shock environment.
Shock test is used to accurately measure the product fragility and evaluate the protective ability of product packaging. To do a boundary assessment on complete product breakage, industrial standard shock pilse or company's internal standards, we can provide the most advanced shock test system to meet your application requirements.
Suitable shock tests for aviation, aerospace, marine, military, consumer electronics, automobiles, home appliances and display devices.
By selecting different waveform generators, it can perform half sinusoidal wave, sawtooth wave, or trapezoidal wave.
FAQ
1. How do you attach the hardware you're testing to your shaker?
By means of a fixture, usually aluminium or magnesium for lightness coupled with rigidity. They can be cast, or smaller fixtures machined from solid stock. Most fixtures are welded.
2. How to select the suitable shock test system model?
Depends on the specimen weight, dimension and testing requirement.
3. The purpose of test?
- Evaluate the product's structural integrity and functional stability under non-repetitive strong impact conditions during use.
- Evaluate the fragility of the outer packaging of the product to protect the structural and functional integrity of the product during transportation.
- When the product is installed on a platform where a collision may occur, it is necessary to assess and test the strength (fracture), rigidity (deformation) of the device used to fix the product on the platform, and the impact on the product.
- Evaluate the impact of possible throw, drop, and free fall on product performance during loading and unloading, transportation or installation, and debugging.
