WebMechanical shock testing typically involves subjecting a test device to sudden and extreme amounts of acceleration or deceleration while instrumentation, such as strain gages, load cells, piezo sensors and more. The goal of the test is to measure the device’s response. Web20 Mar 2024 · 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.

WebShockWatch Activation Curves. The left side of the Frequency vs. Duration curve shows a linear scale and is titled “G” or “G-level.”. This is the acceleration scale. A “G” is a multiple of the acceleration due to gravity (32.2ft/s2, or 9.8m/s2). Five (5) G’s equals five (5) times the acceleration due to gravity. http://www.vibrationdata.com/tutorials2/HSS_test.pdf maserati dealership vancouver bc
