- Abstract
The thesis does the simulation and optimization research aiming at solving the problem of the stability of outlet pulsation in areo engine nozzle control. Based on mathematical model analysis on each component in aero engine nozzle control device, the high-precision modeling of piston pump and controller etc in aero engine nozzle control device was built and studied on simulation and analysis. By comparing the simulated data and experimental data, the error of pressurization value was less than 6% and working flow was less than 5%, the correctness of the simulation method was verified; On the basis of the results of performance simulation in engine nozzle control device, it analyzed the problems of instability that oil pressure pulsation appears in piston pump included nozzle control device, and simulation and optimization were researched. The optimization results show: modulating the parameters of regulator in controller solves the problem of excessive outlet pressure pulsation in the nozzle control device, then the outlet pressure pulsations is reduced from 6MPa to 0.5MPa, and the stability of the nozzle control device is improved.
