【摘要】 自20世纪60年代开始,几乎每一场局部战争都程度不同地使用了导弹武器,导弹武器装备在现代战争中发挥着越来越重要的作用。为了在未来战争中掌握主动权,一批新式导弹武器装备应运而生。导弹武器装备的关键性能指标是保证导弹发射装置在全陆地作业中的稳定性,而其中起竖油缸是发射装置驱动弹体起竖的重要部件。针对发射装置的性能测试,关键是对起竖油缸静动态性能的检验。结合某公司发射装置测试项目,本文对三用车发射装置起竖过程的静动态特性展开研究。通过设计机电液一体化的非标准设备,对起竖油缸进行负载模拟试验,测试起竖油缸加载过程稳定特性、泄漏特性以及可靠性,从而验证产品性能是否满足实际工况要求。研制一种适用于不同型号的通用发射装置负载模拟加载系统,在试验室条件下模拟各种环境下起竖油缸动态性能,就很具有现实意义。本文系统地提出了发射装置负载模拟系统的设计方案。设计了满足油缸轴向式加载的机械结构,研究了两套液压回分别路实现加载油缸控制系统模拟负载和被试油缸控制系统符合实际工况状态。搭建了PLC和上位机组成的测控系统,PLC作为从站负责完成对各个液压阀的控制和实时采集系统中传感器信号,上位机选用Lab VIEW作为人机界面,实现对PLC发送控制命令和读取数据进行绘制状态曲线并记录存储。试验过程中对加载力精度采用模糊PID算法控制,并进行了仿真分析,最后在Lab VIEW平台下实现PID控制。起竖油缸试验结果表明,发射装置负载模拟系统设计研制是可行的,能够满足设计要求。负载模拟系统满足油缸工作行程要求,在加载力200t的极限情况下系统工件结构无变形,设备工作运行安全无异常。经过数据对比,系统较好地模拟起竖油缸实际工况,并准确记录试验数据,能够满足起竖油缸加载过程稳定特性、泄漏特性以及可靠性的测试要求。整个发射装置负载模拟系统设计和研制达到预期效果。

【Abstract】 Since the 1960 s, almost every local war has a varying degree use of the missile. In order to ensure the stability of the missile during the whole land job, a batch of new launchers have emerged. And erecting cylinder plays an important role for the launcher to drive the missile body to erect. The test aiming at the launcher performance is just to check the dynamic performance of erecting cylinder.This topic studies the dynamic characteristics during the erecting process of the three-mode vehicle launcher by combining the launcher test project of a company. By designing the non-standard equipment with integrative technique system of mechanics-electronics-hydraulics, conduct the load simulation experiment on the erecting cylinder to test the stability, leaking and reliability of the erecting cyliner during the loading process, which can verify that whether the product performance will meet the requirements of the actual conditions. To develop a load simulation loading system which can fit for different kinds of launchers to simulate the dynamic performance of the erecting cylinder in varying environments in the lab has practical significance.A design plan of loading simulation system for the launcher was raised in this topic. This design met the requirements of the cylinder axial opposite vertex loading mechanical structure and studied on 2 sets of hydraulic circuit realizing the simulation load of the loading cylinder control system and the control system of the tested cylinder met the actual conditions. It built the observing and control system with PLC and upper computer. As a slave station, PLC was responsible for completing the control of each hydraulic valve and collecting the sensor signal in the system. The upper computer chose the Lab VIEW as the human-computer interface to realize the control commands sending to PLC and data readind to draw status curve for record. It studied the control of sumilation PID algorithm to the loading force accuracy in the test process, conducted the simulation analysis and realized the control at the Lab VIEW platform in the end.The reslut of the experiment of launcher loading simulation system joint debugging and erecting cylinder test shows that the system design is feasible and can meet the requirements. The load simulation system of the launcher is based on the erectric-hydraulic proportional technology so that can simulate the actual conditions of the erecting cylinder and record the test data exactly. And it can also meet the requirements of the stability, leaking and reliability of the cylinder loading process. The design and development of the whole launcher load simulation system achieved the desired results.
