摘要

本文介绍了已建立的NCKU 10cm /spl次/ 10cm磁悬浮风洞的测量与标定。所提出的风洞是基于磁悬浮平衡系统(MSBS)构建的。设计了一种带线球轴承的标定夹具。当前的测量值表示对测试模型施加的力和力矩，是从每个自由度上的外部施加的载荷中获得的。从结果中，利用测量数据，可以直接获得试验模型在各个自由度上的施力和力矩的基本风洞试验。该实用磁悬浮风洞可用于气动试验。

Force and moment calibration for NCKU 10 cm/spl times/10 cm magnetic suspension wind tunnel

This paper presents measurement and calibration of the established NCKU 10 cm/spl times/10 cm magnetic suspension wind tunnel. The proposed wind tunnel is constructed based on a magnetic suspension balance system (MSBS). A calibration fixture with wire-ball bearings was designed for the experiments. Current measurements representing exerting forces and moments on the test model are obtained from externally applied loads on each degree of freedom. From the results, using the measurement data, a basic wind tunnel test to obtain the exerting force and moment in each degree of freedom on the test model can be obtained directly. This practical magnetic suspension wind tunnel can be used for aerodynamic tests.
