Experimental Research And Motion Characteristics Analysis Of Weapons Systems

When the weapon shoot, they accompanied by a large number of vibrations which seriously affect the functions of weapons. From the perspective of dynamics, the vibration may damage the normal circular movement and affect the shooting accuracy of weapon seriously. In this circumstance, we must measure the vibration parameters of launcher.At the same time, we can make use of high speed photography collections to achieve the motion characteristics of bullet. It is significant to improve the shooting accuracy of launchers by researching vibrations and the motion of bullet. This paper intends to design a set of perfect testing system about launcher vibration and the motion of bullet.The test system is split into two parts:The launcher vibration testing system and the bullet motion testing system. On the one hand, the former uses piezoelectric acceleration sensor and the piezoelectric fluidic gyroscope as a sensor to measure the vibration caused by launcher when it shoots. First, make a design on hardware about the launcher vibration testing system. By comparing the advantages and disadvantages of various kinds of hardware, choose suitable hardware for this test system;Secondly, write the corresponding measurement software for the system which gather sensor signal including human computer interaction, testing and processing and displaying data by using LabVIEW programming language;On the other hand, the latter mainly uses high speed photography collections to achieve the motion of bullet, then uses VC++to enhance and tailor the images that collected before. Finally, we will get the motion image of bullet clearly so that analyze the motion of bullet.According to the empirical experiment, the indicators from the system of vibration and bullet motion of these launchers are up to the designing goals and meet the realistic requirements. In addition, it can measure the instantaneous impact vibration fast and accurately and can capture the images of motion of bullet clearly when launcher shoots.
