摘要
本文研究考虑桨叶挥午和摆振弯曲、桨角变化以及扭转与纵向振动耦合的螺旋桨—减速器—发动机系统固有特性计算问题。通过算例验证 。
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.
