Abstract:
In order to investigate the effect of transient flow velocity on nonlinear vibration characteristics of fuel pipeline in attitude control engine, a nonlinear liquid-solid coupling model of fuel pipe was developed and simulated by use of the weighted residuals method and the fourth-order Runge-Kutta method. The effect of the opening and closing time of the solenoid valve on the nonlinear vibration of fuel pipe was studied under different transient fuel flow rates. The results show that the pipeline vibration can be divided into stable vibration zone and unstable vibration zone according to the pipeline characteristic curve, and the unstable vibration is mainly manifested as divergent instability and distensibility instability. When the opening/closing time of solenoid valve locates in the instability region, the multi-frequency and variable amplitude expansion vibration of fuel pipeline will be induced by the transient flow velocity of fuel because of the sudden opening of the solenoid valve and the increased flow velocity of fuel is one of the mainfactor that results in the cracks of fuel pipeline. However, the single-frequency and variable amplitude expansion vibration of fuel pipeline is caused by the unstable vibration of the fuel pipeline due to the sudden closing of the solenoid valve.
