摘　　要：基于某大质量电磁发射装置研究背景,针对螺杆气压式高平机驱动俯仰系统运行过程中的气电作用特性展开研究。建立了发射系统动力学模型,结合高平机结构和布局特征,对俯仰系统动力学运行过程中高平机气电参数进行了理论分析和试验验证,得到了两种不同工况运行条件下气压平衡效果、系统电流、功率等变化规律。理论计算结果和试验结果对比分析表明:螺杆气压式高平机气压作用可最大降低整体重力不平衡力矩的89.9%,匀速工况下可最大降低75.4%的系统运行功率,对系统电源需求和结构紧凑化设计非常有利;所提的高平机理论计算结果和试验数据吻合较好,研究成果对大质量火炮瞄准机设计具有参考意义。Based on the research background of a large-mass electromagnetic launch,the gas-electricity characteristics during the operation of the pitch system driven by the screw pneumatic elevating equilibrator were studied.A dynamic model of the launch system was established,and combined with the structure and layout characteristics of the elevating equilibrator,the theoretical analysis and experimental verification of the gas-electric parameters in elevating equilibrator during the dynamic operation of the pitch system were carried out,and thus variation laws of the air pressure balance effect,system current,power under two different operating conditions were obtained.The comparative analy-sis of the theoretical calculation results and the test results show that the air pressure action of the screw pneumatic elevating equilibrator can reduce the overall gravity unbalance torque by 89.9%,and the system operating power can be reduced by a maximum of 75.4%under constant speed conditions,which is very beneficial to system power requirements and compact design.The theoretical calculation results of the elevating equilibrator are in good agreement with the experimental data,which may serve as reference for the design of large-mass gun aiming machines.
