摘要
为了满足火炮动力后坐模拟试验时瞬态强冲击力的要求,设计了一种以液压为动力源、以炮口冲击力代替炮膛合力作为后坐动力的模拟试验装置。重点阐述了液压动力子系统和冲击子系统的设计方案,并建立了被试火炮在0°射角时两个子系统的简化数学模型。基于ADAMS与EASY5软件,开发了火炮动力后坐模拟试验装置的仿真模型,实现了火炮动力后坐模拟试验过程的协同仿真。仿真结果表明,该试验系统设计方案可行,系统参数设置合理,为火炮动力后坐模拟试验装置的物理样机研制提供了依据。
In order to meet the requirements of transient and strong impact force during the process of dynamic recoil simulation test,taking hydraulic power as the driving forceand taking muzzle impact force instead of the bore force as recoil power,a kind of test machine was designed.A scheme of the test system which consists of hydraulic power subsystem and impact subsystem was emphatically described,and the simplified mathematic models of these subsystems were built up under the condition of that the quadrant angle was 0°.Based on ADAMS and EASY5 software,the simulation model of the test machine was developed.Co-simulation of the virtual firing test was carried out.The simulation results indicated that the design scheme of the test system is feasible and the system parameters are rational.This kind of scheme can provide a theoretic basis for physical prototyping.
