中文摘要:
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.
English Summary:
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.
