摘要
为缩短车载导弹发射装置起竖时间,降低系统装机功率,提出一种基于燃气挤压器式辅助动力源的快速起竖方案.建立描述燃气挤压器式辅助动力源起竖过程的气、液、机多物理系统耦合数学模型.在Matlab/Simulink中搭建燃气发生器内弹道求解模块,在AMESim中构建挤压式油箱、液压元件和机械机构仿真模型,以燃气发生器喷管质量流量和挤压式油箱燃气腔压力为传递变量,实现联合仿真,并基于原理样机试验对燃气挤压器仿真模型的有效性进行了验证.分析了起竖装置的快速性和功率特性,并与传统泵式液压起竖装置进行了对比.研究结果表明:新型起竖装置可在34.5 s内实现快速起竖,起竖时间缩短了42.5%,总装机功率仅为11.6 kW,降低了38.9%,大幅提高了系统的起竖速度,显著降低了系统的装机功率.
In order to reduce the erection time and the installed power of vehicle borne missile launcher,a rapid erection scheme was proposed based on gas-squeezer auxiliary power source.A mathematical model of the erection progress was presented to couple the mechanical,fuel gas and fluidic equations.The interior ballistics equation of gas generator was solved by Matlab/Simulink,and the simulation models of the squeezing tank,the hydraulic components and the mechanical device were built in AMESim.A prototype test of the gas generation device was carried out,to validate the co-simulation model.Based on the simulation results,the gas-squeezer system was compared with traditional pump-type system.The results show that the erection progress of the gas-squeezer system can be achieved within 34.5 s,shortened by 42.5%,and the installed power is only 11.6 kW,decreased by 38.9%.The new system can greatly increase the erection speed and reduce the system power.
