摘　　要：针对高速飞行器的变形需求,提出一种新型飞行器变形舱体形式,并设计一种多维变形机构与预紧堆叠蒙皮结构实现舱体多维变形。多维变形机构由多组单自由度双滑块六杆变形机构与6-UPS并联分布式驱动机构组成。针对变形舱体的试验验证,提出了变形舱体随动力热加载方法,此方法能够实现静态加载、时变力随动加载和恒定力随动加载。推导了随动加载系统理论模型,并基于理论与仿真分析,验证了随动加载力分析的正确性。开展了变形舱体随动力热加载试验验证,试验结果误差在允许范围内,验证了理论与仿真分析的正确性以及随动力热加载方法的可行性。Aiming at the morphing requirements of high-speed flight vehicle,a new morphing fuselage is proposed,and a multi-dimensional morphing mechanism and pretension stacking skin structure is designed to achieve multidimensional morphing of the fuselage.The multi-dimensional morphing mechanism consists of multiple sets of single DOF double slider six-bar morphing mechanisms and a 6-UPS parallel distributed actuated mechanism.A tracking-loading method for morphing fuselage is proposed to meet the experimental verification.This method can achieve static loading,tracking loading with time-varying force,and tracking loading with constant force.A theoretical model of the trackingloading system is derived,and based on theoretical and simulation analysis,the correctness of the tracking-loading force analysis is verified.Tracking-force and thermal loading tests of morphing fuselage are conducted,the experimental results show that the errors are within the allowable range,which verified the correctness of theoretical and simulation analysis and the feasibility of the tracking-force and thermal loading method.
