Study on Model Aerodynamical Measurement with Wire-driven Parallel Suspension in Low-Speed Wind Tunnel

Abstract

将绳牵引并联机构应用于低速风洞模型支撑是近年来随着并联机构与力控制技术发展而提出的一种新概念。它作为一种新式支撑具有传统支撑不可比拟的优势。然而目前对于这种“软式”支撑的实验研究还处于起步阶段,鲜见有关该类支撑风洞吹风的试验结果。本文对此开展了相关研究,提出通过测量牵引绳拉力变化解算实验模型风洞吹风试验所承受的气动载荷的方法,并构建了测力系统,通过风洞吹风试验对实验模型气动参数的获取方法进行了初步的验证。 本文的主要工作如下: 首先,针对风洞传统支撑的方式及其缺点,分析了传统的风洞试验中模型气动参数的测量方法,阐述了绳牵引并联机构用做风洞试验支撑系统的诸多优势,体现了本文研究的背景和意义。...With the recent development of parallel mechanism and force control technology, a new concept is proposed by using the wire-driven parallel manipulator as model suspension system in low-speed wind tunnel tests. As a new style suspension, it shows an irreplaceable superiority over the traditional support system. However, the research on the “soft-style” suspension is still at the primary stages, an...学位:工学硕士院系专业:物理与机电工程学院机电工程系_机械制造及其自动化学号:1992006115183
