Abstract
Setting an embedded weapon bay is an effective means of avoiding radar detection for modern stealth warplanes.In the allowable time and flow range,in order to ensure that the weapons bay doors are in place,a system model is established in AMESim,and closed loop control of the system is achieved by a three loop control strategy.The effects of design parameters such as displacement tolerance,low speed range on the dynamic characteristics of the system are analyzed.After analysis,if the displacement tolerance is too large,it will cause system jitter on the premise of ensuring the system in place time;if the displacement tolerance is too small or the low speed range is too long,it will result in excessive system flow consumption.If the low speed range is too short,it can make the system's end speed excessive.Finally,the control strategy and design parameters,such as displacement tolerance and low rotation speed range,are verified by the material object of weapon bay door drive system.The results show that the design of the three loop control strategy is reasonable,and the system can operate stably by the choose of suitable design parameters.At the same time,the theory and method involved in this study can also be extended to hydraulic actuators and hydraulic pumps and other fields,with important practical significance.关键词
