Description

technical field [0001] The invention relates to the technical field of energetic material testing, and more specifically relates to a friction speed control device for friction sensitivity testing and a control method thereof. Background technique [0002] Friction sensitivity test is one of the important test items to evaluate the sensitivity of energetic materials to external stimuli. It plays an important supporting role in the formulation and application design of explosives, and is especially important for insensitive explosives whose main feature is low sensitivity. However, due to the low sensitivity of insensitive explosives, the intensity of frictional stimulation that can be applied by conventional frictional sensitivity testing devices is difficult to meet its reaction excitation conditions. In order to accurately calibrate the friction sensitivity of insensitive explosives, a longer friction stroke is required. [0003] In the friction sensitivity test of energe...
