摘要本文参照液压缸设计理论,以S400防空导弹和“爱国者3”防空导弹发射车支腿为参考,对火箭炮单缸摆臂式千斤顶进行了结构设计。通过理论分析和计算,得到了驱动液压缸、上摆臂、下摆臂和和支撑杆的结构、材料选择、基本尺寸、连接方案。通过发射车稳定性计算得到了支腿横向跨距,设计了平行四边形连杆机构的支腿伸展收回方案。通过支腿反力计算得到了液压缸的工作负载以及摆臂支腿的载荷。采用三文建模软件solidworks对摆臂式千斤顶各个零部件的结构设计、零部件分解及仿真装配。通过有限元分析模拟了在工作状态摆臂支腿各构件的应力分布和变形状况,结果显示发射车摆臂支腿强度、刚度满足技术要求。32606

Title Rocket single-cylinder swing arm design
Abstract
According to the design theory of Hydraulic cylinder ,Reference design of hydraulic cylinder with S400 air defense missiles and "Patriot 3" anti-aircraft missile launch vehicle Outrigger is any guide, the rockets set single-arm structure design of the Jack. Theoretical analysis and calculation have been placed on driving hydraulic cylinder, boom, hem and and the structure of the support bar, choice of materials, basic dimensions, connections program. By launch vehicle stability calculation leg horizontal span, designed a parallelogram linkage of leg stretch-back programme. Hydraulic cylinder is obtained by leg reaction force workloads and swing arm leg loads. Using SolidWorks modeling software on the swing arm type jacks in all parts of the structure decomposition and simulation design, parts and Assembly. By means of finite element analysis to simulate the working arm leg stress distribution and deformation of the components shown Launcher arm leg strength and stiffness to meet technical requirements.

对于多管联装火箭炮而言,前一发火箭弹发射时各种影响因素将引起发射装置的振动,为了有效的改善发射装置的振动规律,减小振动和保持发射平台平稳,常常采用支腿将发射装置或运载体支撑于地面(图1.1、图1.2),增强发射系统总体刚性[1]。
