摘　　要：为检验表面桨驱动装置能否安全可靠地运行,采用UG软件进行双十字万向联轴节的运动仿真计算,运用有限元方法对各典型零部件进行强度计算及轴系回旋振动计算,采用系统矩阵法分析装置的扭转振动特性,结合轴系扭振计算与校中计算,采用理论公式对轴系进行综合强度校核,得到双十字万向联轴节的运动干涉数据、各典型零部件应力大小及分布情况、轴系扭振应力大小等数据,并对表面桨驱动装置设计计算中的关键技术进行研究,提出计算分析的流程,可为表面桨装置设计及计算与分析提供理论及工程指导。In order to test whether the surface drive propeller can operate safely and reliably, Unigraphics NX is used to simulate the motion of the double cross universal coupling. The finite element method is used to calculate the strength of typical component and the whirling vibration of shaft system. The torsional vibration characteristics of the device are analyzed by the system matrix method. Combining the calculation results of whirling vibration and torsional vibration, theoretical formula is used for the comprehensive verification of the whole system. Consequently, the kinematic interference data of the double cross universal coupling, the stress magnitude and its distribution of the typical components, torsional vibration stress and other data are obtained. Study on key technologies of the design and calculation of the surface drive propeller is made. The analysis process is summarized which can provide theoretical and engineering guidance for the design, calculation and analysis of surface drive propeller devices.
