Webb18 okt. 2024 · Shocks are very short and high intensity loads (i.e., high peak acceleration and high frequency content) caused by separation and deployment events that can damage spacecraft hardware. Shock testing either involves the application of a shock pulse or a shock response spectrum (SRS) vibration at the mechanical interface of the test article. Typically, shock tests are a sharp transfer of energy into a mechanical system to test a system’s capability to survive a drop, hit, impact, fall, explosion, or any other source of transient vibration. The shock pulses can range in time duration from a few milliseconds to upwards of one minute. Visa mer Many product test standards require shock pulses for product qualification, durability, and reliability. Shock pulses are defined in the test standard and are classified as either a classical shock pulse or a … Visa mer Classical shock testing is run on mechanical shock machines, electrodynamic shakers, or servo-hydraulic shakers.
