Title   The development of device for the  test and storage of the motion parameters in the bore of the projectile-the hardware part                       
Abstract
Accurate measurement of the Metal Storm Weapon projectile acceleration and the top and bottom pressure provides effective technical means and data support for the development and evaluation of the Metal Storm Weapon, as while as the analysis modeling of interior ballistic movement characteristics.
Based on the above parameters, this paper proposes the overview scheme of the storage test.
The system consists of six parts including sensors, signal conditioning, AD acquisition, microcontroller, batteries and high-strength shell. And select PVDF piezoelectric pressure sensor and acceleration sensor according to the characteristics of the measured object; moreover, the system designs charge amplifier and low pass filter circuit for signal conditioning, and uses chip AD7324 for AD conversion and data acquisition. The data will be collected in the FLASH of STM32.
PC gets the data through serial port and then give an analysis and display of the data. The design uses Altium Designer software to design circuit diagram of the system and make PCB. The results of the circuit debugging show that the designed memory test circuit can complete the functions required in the task book.
