The catapult performance increases with the gas cylinder pressure, cylinder volume, ejection cylinder bore. ( 3 ) The pneumatic system, effect of damping holes on the performance of the system significantly. 弹射器的性能随着贮气瓶充气压力、贮气瓶容积、弹射气缸的缸径的增大而增强。(3)气动系统中,阻尼孔对系统性能的影响显著。
Because of the disadvantages of pneumatic system such as weak stiffness and little damping ratio, pressure feedback is introduced into controllor in experiment to increase damping ratio and improve static and dynamic performance of the system. The experimental device, experimental results and the analysis are presented. 针对气动系统刚度低、阻尼小、易振荡的特点,实验中引入压力反馈补偿,提高系统的稳定性和动态性能,给出了实验装置、实验结果和分析。
