Environmental simulation: Mechanical shock
Shock-like stresses occur with every product. The causes of these mechanical shocks are very diverse and sometimes even underestimated.
Falling packaged goods, rough setting down or driving over potholes during transport can lead to massive mechanical impulse loads. During the operation of devices, significantly higher shock loads arise due to the location or specific installation. One example is a speaker installed in a car door. Every "slamming" of the door generates a mechanical shock. The same way mechanical shock loads that can lead to product failure occur in every environment and at every stage of a product's life. Early testing improves the information basis for the design and service life assessment of a product.
Do you know all possible shock loads that affect your product?
How does your device react to these kinds of loads?
At Treo, we can reproduce mechanical shock loads with various parameters for you. Our electrodynamic shakers are able to simulate semi-sinusoidal, sawtooth-shaped and trapezoidal pulses with freely definable accelerations and shock durations. If the expected accelerations are very high, as is the case in the military or aerospace sectors, Treo uses hydraulically or pneumatically operated shock tables.
The standards and procedures in this area include the following:
- DIN 60068-2-27 Test Ea: Shock
- MIL-STD-810 Shock
- RTCA DO-160 Operational shocks and crash safety
- DIN EN 60068-2-31 Test Ec: Rough handling shocks, primarily for equipment-type specimens
