Title Reverse recoil device of dynamic loading test bench——
Hydraulic driving device design
Abstract
This paper focus on the application and development of hydraulic system. According to the requirements of the subject，a all-round designation of the hydraulic system is made which mainly includes determining the load parameter of different working situations， calculating main parameters of hydraulic components, and selecting appropriate basic loop. Firstly, according to those parameters, we chose proper components and conducted a final check to make sure their effectiveness. Secondly, based on the analysis of the hydraulic system and the understanding of hydraulic theory, we designed the hydraulic pressure system, circulation and supply scheme. Thirdly, according to the basic circuit in different working conditions, we put hydraulic circuits together to make the hydraulic system. Then,we determined the location of each hydraulic components. In the end,we ensured the final designation of the hydraulic system could control the recoil mechanism artificial recoil and back into the cylinder, and satisfy the requirements of the action cycle.

1.1 研究背景与意义
火炮是人类武器发展历史上出现最早的热兵器，今天在各种高新技术的装备中，它仍然是各军兵种的主要火力手段[1]。在火炮技术发展的几个世纪的漫长岁月中，火炮威力与机动性的发展一直是贯穿整个火炮设计的矛盾斗争。而反后坐装置就是这一基本矛盾的产物，火炮上有无反后坐装置是区别火炮是刚性炮架还是弹性炮架的标志[2,3]。
