摘要

为解决车载导弹起竖装置起竖时间长、动力源体积大的问题，提出一种新型燃气挤压器驱动的快速起竖方案。建立了起竖过程一体化计算数学模型，对比分析了恒定燃面和变燃面两种起竖方案，设计了基于装药燃面与凸轮型面优化的气液分段控制策略：起竖前段，采用变燃面燃气发生器控制燃气输出流量，在实现快速启动的同时保持负载匀速起竖；起竖后段，采用凸轮调速阀控制油液输出流量，完成负载的减速制动，保证负载平稳停靠。研究结果表明：新型燃气挤压器式动力源起竖方案及其控制策略可实现导弹16s快速、平稳起竖，较传统液压泵式动力源的起竖时间大幅缩短，可为车载导弹起竖装备的升级改造和工程研制提供设计依据。

Abstract

A rapid erection scheme of a vehicle borne missile launcher was proposed.The scheme was based on gas-squeezer in order to reduce both the erection time and the volume of the power source.An integrated model describing the whole progress of erection was established.Two erection schemes, with constant and variable burning area respectively, were compared and analyzed.A gas-liquid subsection control strategy based on optimization of grain burning area and cam profile was designed.In the first erection stage, the gas generator with variable burning area was applied, which helps to start up quickly and then keep a uniform speed.In the second erection stage, a speed control valve was used to control the process of deceleration, braking, and smooth parking.The spool of the speed control valve was controlled by a cam.Simulation results show that the erection progress can be achieved in 16 s, and the final parking process is smooth.Comparing with the traditional scheme based on hydraulic pump, the erection time is shortened significantly by inducing gas-squeezer.The scheme can provide an important design reference for the upgrading of the erection equipment.
