Abstract


Several issues concerning shock accelerations production by pneumatic shock machines are considered in the paper. A new method of the required half-sine pulses amplitude ensuring is proposed and theoretically justified. The method is based on the dependence of a shock machine rising height on speed and duration of compressed air supply to pneumatic cylinders that ensure rising and dropping of a test object. A design of the SMU300 pneumatic shock machine used to conduct the method experimental research is considered here. Experimental data have confirmed the effectiveness of the method. An algorithm for setting the design and technological parameters of a shock machine ensuring the required test parameters is proposed.
