Unlike impact testing where the event is uncontrolled, a mechanical shock test defines the pulse’s shape, duration, and amplitude. Mechanical shock tests include pyrotechnic shock, drop shock, and free-fall shock.

机械冲击试验又名：mechanical shock. 碰撞试验的技术指标包括：峰值加速度、脉冲持续时间、速度变化量（半正弦波）、每方向碰撞次数。 注意冲击和碰撞的方向应是6个面，而不是X、Y、Z 三方向。 在环境试验中，振动、冲击和碰撞是有共通点的：这三种试验都是可以作为对产品本身机构强度的一种有效检验手段。 但是 振动试验 讲究持续性，疲劳性。 像产品在运输过程或者一些发动机上的元件在运行时都是一个长期的过程。 冲击试验是瞬间性的，破坏性的。 理论上 跌落 …

机械冲击试验是可靠性试验中的一种，它是检测产品在遭受外力冲击时是否可以正常运行的一项实验。 现代生产中，产品在生产、运输、装卸、使用过程中，不可避免地受到冲击、碰撞、跌落、翻倒等作用，这些瞬间的力会…

机械冲击试验(Mechanical Shock)为评估芯片封装上板(Board Level)后，在制程、包装、运输及日常使用状况时，当电路板受动态剧烈弯曲时，锡接合位置(Solder Joint)是否产生断裂而影响寿命。

Shock testing typically falls into two categories, classical shock testing and pyroshock or ballistic shock testing. Classical shock testing consists of the following shock impulses: half sine, haversine, sawtooth wave, and trapezoid. Pyroshock and ballistic shock tests are specialized and are not considered classical shocks.

Mechanical shock testing helps determine whether a device can remain functional when subjected to sudden, abrupt motion changes associated with service environments like product handling, shipping/transportation, rocket stage separation, weapon firing, etc.

2023年8月21日 · Mechanical shock test machines employ a purely mechanical system, such as a drop tower or a pendulum, to generate shock forces. These machines are particularly well-suited for testing larger and heavier test items, including automotive components and military equipment.

2024年8月21日 · Mechanical shock testing is essential for any product that may be exposed to impact or sudden forces during its lifecycle. By understanding how a product responds to these conditions, manufacturers can improve their designs, ensure product reliability, and maintain consistent quality across production batches.

Mechanical shock often leads to nonstructural failures in both mechanical and electrical systems. Our expert-led testing program supports manufacturers by conducting rigorous mechanical shock testing to ensure products can withstand sudden impacts without sustaining damage while identifying where a product’s limitations lie.

2020年3月20日 · Shock tests are typically a sharp transfer of energy into a mechanical system to test the system’s capability to survive a drop, hit, impact, fall, explosion, or any other source of transient vibration. Products from industries like defense and electronics must properly function after shock events in the end-use environment (EUE).
