Application
Shock test system measures the strength, continuous impact resistance, and fragility of the specimen. For the shock testing, we can evaluate how the products respond to specific shock inputs. From the results, we can study the capability of products withstand its real environment shock. Shock testing is usually performing the shock resistance of electronics products such as computer parts, mobile devices and etc.
We have wide range of shock test system, we can recommend a suitable model for many testing applications based on the size and weight of the biggest test specimen, this can determine the table surface area, and shock system capacity. Besides that, the shock testing requirements such as velocity change and acceleration level, shock pulse waveforms also important information in selecting suitable shock test system.
The technical specifications of the impact test include: peak acceleration, pulse duration, speed change (half sine wave, post-peak sawtooth wave, trapezoidal wave) and waveform selection. There is no special requirement for the number of impacts, and each face is impacted 3 times for a total of 18 times. Many products are subject to impact during use, handling, and transportation. The magnitude of the impact varies widely and has complex properties. Therefore, the impact and collision reliability test is suitable for determining the weak points of the machine and assessing the integrity of the product structure.
Test requirement information:
– Half sine wave
– Trapezoidal wave (square wave)
– Triangle wave (forward sawtooth and back sawtooth)
-Impact type: half sine / square wave impact acceleration pulse width / speed change rate (square wave)
