摘要

本文提出了无人潜航器（UUV）轴系统的多体动力学模型，该模型考虑了弹性联轴器、球轴承和弹性支撑。通过有限元分析计算了弹性联轴器的刚度特性。研究了负载条件、轴承位置和支撑刚度对轴振动的影响。然后，对轴承位置和支撑刚度进行了优化。这项研究为 UUV 轴系统的设计和振动优化提供了一些指导。

Multibody dynamic study and optimization for a flexible support shaft system in unmanned underwater vehicle

This paper presented a multibody dynamic model for the shaft system in an unmanned underwater vehicle (UUV), the model considers the flexible coupling, ball bearing and flexible support. The stiffness characteristics of flexible coupling are calculated by using the finite-element analysis. The effects of load condition, bearing location and support stiffness on shaft vibrations are investigated. Then, an optimization for the bearing locations and support stiffness is conducted. This study provides some guidance for the design and vibration optimization of the shaft system in UUVs.
