Abstract

Abstract

In this paper the calculation problems of modal characteristics are studied for a propeller gear box engine system considering the flapwise and lagwise flexibilities,the pitch angle of the blalde and the coupling of torsional vibration with longitudinal vibration.The experessions suitable for computer are deduced for calculation of the modal characteristics.An numerical example for a propeller gear box engine system demonstrates that the method is reasonable and feasible.
