Title The design of ballistic equipment for a Large-caliber bullet

Abstract The large-caliber bullet with the characteristics of high range,,high powerful,high precision and persified is the effective way to fight high value targets。Large-caliber missile equipment is necessary equipment for large-caliber bullet experiment。This paper designs a kind of large-caliber missile equipment。 Under the condition, which given the designated ammunition record index, the paper discusses how to design the internal trajectory; ensure the firing parameter and the elements of ballistic equipment’s inner bore structure are logical。 Also, it can provide the experimental equipment for the study of large-caliber missile。 Firstly，on the basis of sufficient investigation, it determines the tactics and technical indicators, presents the overall scheme and completes the design work of structure。 Secondly, it establishes the internal ballistic calculation model of this kind of ballistic equipment。 By compiling program and calculation, we can get the interior ballistic parameter of maximum bore pressure, projectile muzzle speed and other important data。 Thirdly, it optimizes the internal ballistic performance; calculates the charge quantity, projectile mass and chamber volume and analyzes the influence of interior ballistics trajectory caused by the bore stroke; then confirms the final parameter。 Finally, the paper design the part structure and then analyzes and calculates the part strength。
