摘要
小型低速实验风洞设备，作为航空航天领域的基础支撑，对于国家在这一重要领域的发展具有举足轻重的影响。它不仅是研制新型飞行器的关键环节，更是武器装备研发和国民经济腾飞的助推器。每当有新的飞行器构想诞生，都需要在风洞中进行详尽的试验，确保其性能达到预期。
回顾空间机构学的发展历程，串联机构的崛起曾引领风潮，而近二十年来，并联机构的兴盛又为其注入了新的活力。如今，在科技飞速发展的背景下，为了展现我国的创新精神和在新兴产业中独树一帜的追求，混联机构正成为高端技术应用的新宠。
本文聚焦于小型低速实验风洞机构的现状及其发展趋势，同时简要探讨了小型低速实验风洞的重要性。在此基础上，我们精心设计了小型低速实验风洞运动机构的结构，并利用SolidWorks软件完成了其三维造型。为确保机构的安全与高效，我们对关键节点进行了强度校核和力学性能分析，并据此选择了适合的电机。最后，我们对本课题进行了总结，并对未来的发展前景进行了展望。

Abstract
Small and low-speed experimental wind tunnel equipment, as the basic support in the aerospace field, has a decisive impact on the development of the country in this important field. It is not only the key link in the development of new aircraft, but also the booster for the research and development of weapons and equipment and the take-off of the national economy. Whenever a new aircraft concept is created, detailed testing in a wind tunnel is required to ensure that its performance is as expected.
Reviewing the development course of space mechanism science, the rise of series mechanism once led the trend, and in the past 20 years, the prosperity of parallel mechanism has injected new vitality into it. Nowadays, under the background of the rapid development of science and technology, in order to show the spirit of innovation in China and the unique pursuit in the emerging industries, hybrid institutions are becoming the new favorite of high-end technology application.
This paper focuses on the current situation and development trend of two degrees of freedom, and briefly discusses the importance of small low-speed experimental wind tunnels. Based on this, we carefully designed the structure of the two degrees of freedom motion mechanism, and completed its three-dimensional modeling with SolidWorks software. In order to ensure the safety and efficiency of the mechanism, we conducted the strength check and mechanical properties analysis on the key nodes, and selected the suitable motor accordingly. Finally, we summarize this topic and look the future prospects.
