The purpose of this study is to design a high‐shock acceleration apparatus that can be used in a laboratory, alleviating the need for expensive and complex experiments. The key components of this device include a detonator, dynamite, a shock transmission bar, the housing for the test object, and an accelerometer. The device uses the detonation of the dynamite to generate instantaneous accelerations of up to 10 5 m s −2 , which last for hundreds of microseconds. The acceleration forces over the most significant frequency range of the system were analyzed using the shock response spectrum (SRS) method. The device output provides a test sample of 1 kg with the high‐acceleration shock condition required by the Mil‐Std‐810F shock test specification.
