摘　　要：运载火箭时序姿控系统消反峰电路采用“二极管+电阻”电路与“电阻+二极管+稳压二极管”电路,利用MULTISIM进行仿真,并利用试验进行验证,发现消反峰电阻越大或者稳压二极管稳压电压越大,电磁阀理论关断时间均越小。对于相同的电磁阀关断时间指标要求,增加稳压二极管稳压值的方法产生的反峰电压要低于增大电阻产生的反峰电压;电磁阀通过精确控制燃料和气体的流动,确保其按照预定的比例和时间被送入发动机,所以增压阀、安溢阀、辅助动力电磁阀等在姿控系统中承担着调节压力和安全保护的重要作用,维护着火箭的姿态稳定和飞行安全,故其关断时间和反峰电压需要精确控制。The anti-peak circuit of the timing attitude control system of the launch vehicle adopts a"diode+resistor"circuit and a"resistor+diode+voltage regulator diode"circuit.MULTISIM is used for simulation and experimental verification.It is found that the theoretical solenoid valve shutdown time becomes shorter when anti-peak resistance grows larger,and the voltage regulator diode voltage goes larger,separately.Regarding the same electromagnetic valve shutdown time index requirements,a lower reverse voltage produced by using the method of increasing the voltage regulator than using the method of increasing the resistance;Due to the precisely controlling of the flows of fuel and gas that are ensured to be delivered to the engine in the predetermined ratio and time,the boost valve,relief valve and auxiliary power solenoid valve. play an important role of adjusting regulating pressure and protecting safety in theattitude control system, which maintain the stability of the launch vehicle's attitude and flight safety.Therefore, their shutdown time and anti-peak voltage need to be precisely controlled.
