Abstract:
In the field of the modal parameters identification of liquid rocket engines, the frequency method is widely used, but it has some shortcomings, such as power reveal, frequency domain aliasing and off-line analysis. Moreover, it may need complex equipment for vibration. In this paper, the method of ARMA based on time-domain identification is applied to this field. By using this method, more accurate modal parameters were obtained by calculation. Besides, the nonlinear effects on the structure of the liquid rocket engine were tested. The method of ARMA improved the computational efficiency and extended the identification range of parameters of liquid rocket engine. It laid the foundation for the parameters identification of the
