Aiming at the characteristics of gun chamber pressure test
a new chamber pressure testing system is designed using MEMS accelerometer MMA8453Q and MSP430.The single chip storage with the function of inversion electricity and the infrared transceiver
etc
is realized.The buffering characteristics of circuit module using ANSYS is simulated and analyzed
and the anti-overload test is carried out using the Machete hammer.The test results show that it can work normally after being impacted by 4.5 × 10 4 g n.Which can meet the test requirements of high impact occasion
