折叠翼变体飞机的传动机构设计和驱动方式优化分析

变体飞机能够在飞行过程中显著地改变外形和尺寸,从而使单一的飞行器能够实现在起飞、俯冲、巡航等多种飞行状态下都具备优良的飞行性能.折叠翼变体飞机的折叠传动机构对折叠翼的结构动力学和传力特性具有显著的影响.本文设计了一种轴/轴套式的折叠传动机构,利用ANSYS有限元软件建立了有限元网格模型,采用DYNA求解器,详细求解分析...

The Transmission Design and Driving Optimization of Folding Wing Aircraft

Morphing aircraft can change shape and size substantially in-flight to enable a single vehicle to perform multiple mission roles.The majority of shape change occurs in the wing resulting in a wide variety of changes in aerodynamic and structural features.The transmission instrument of the folding wing resolves special design,because the structure dynamics and transmission feature of folding wing will vary in motion.In this paper,a novel transmission instrument was designed using shaft and shaft sleeve,whose...
