摘要
为分析弹性桨-轴系统的纵向振动传递特性,建立了质量点桨-轴和弹性桨-轴2种模型,分析其传递路径,比较不同材料桨-轴系统在推力轴承处的响应和力传递率,并对弹性桨-轴系统进行频率匹配设计。得出如下结论:桨叶的弹性效用对于纵向振动的传递有调制作用;通过调整桨叶的弹性参数,匹配好桨叶伞形模态和轴系纵振模态,可以有效控制轴系的振动。
In order to analyze the longitudinal vibration transmission characteristics of elastic propeller shaft system,two models of point mass propeller shaft and elastic propeller shaft are established, their transmission paths are analyzed, the response and force transmission rate of propeller shaft system of different materials at thrust bearing are compared, and the frequency matching design of elastic propeller shaft system is carried out. The conclusions are as follows: the elastic utility of the blade can modulate the transmission of longitudinal vibration. By adjusting the elastic parameters of the blade and matching the umbrella mode of the blade and the longitudinal vibration mode of the shaft system, the vibration of the shaft system can be effectively controlled..
