研究生优秀毕业论文 Abstract 硕士学位论文 Abstract The ammunition automatic loading system of large caliber canon is an important part to improve the speed of fire of realization bat target depends on its work state paper has carded out a storage test device to test the process state parameters in the process of loading and the correlation between running state and detection signal aiming at the characteristics of state parameters in the process of system running. The physical models of magazine,coordinator and ramming mechanism,which have high fault rate,are established respectively based on ADAMS aiming at the running characteristics of the three change of state parameters of proj ectile when the system is running is simulated and storage and test approach based on triaxial acceleration is determined to monitor the stationary performance of projectile in the running of system. The corresponding acceleration sensors are chosen according to the rage and仔equency of acceleration awaiting measurement in different three-channel constant current source module based on LM3 1 7,signal processing module based on OP07CS8,main control module based on STM32F 1 03RC8T6,A/D conversion module,storage module based on munication module based on USB virtual serial port have been programs of acquisition,storage munication of puter based on C language are designed which realize the function of acquisition,A/D conversion and storage of data and munication of man-machine interface and the smoothing processing,analysis and storage program of data are designed based on LabVIEW which realized the back·read processing and displaying of the acceleration structure of storage test device according to the requirements of installation and protection of test device is designed. The performance of signal conditioning module,data acquisition and storage module of storage test device is tested and verified
