Simulated artillery chamber pressure generator for special dynamic evaluation
نویسندگان
چکیده
A simulated artillery chamber pressure generator (SACPG) was proposed for solving the dynamic evaluation in application environment of internal electronic pressure gauge. Strength autofrettage theory of SACPG was studied and simulated by ANSYS. Pressure waveforms, of which the amplitudes were up to 700MPa and the rise time was between 2 ms and 5 ms, had been obtained through controlling the diaphragm thickness and charge quantity. Simulation and test results show that the device can effectively simulate artillery chamber environment, which provides the feasibility evaluation of the internal electronic pressure gauge .
