摘　　要：为提高风洞迎角机构的精准度,采用一种基于分体蜗杆技术的蜗轮蜗杆副对4 m×3 m低速风洞迎角机构进行改造。分析分体蜗杆技术的原理及实现,并对改造后的迎角机构进行静态和动态测试。结果表明:采用分体蜗杆技术的迎角机构能提高迎角的定位精度和试验数据质量,为该风洞后续试验的开展奠定良好基础。In order to improve the accuracy of the angle of attack mechanism of the wind tunnel,the angle of attack mechanism of the 4 m×3 m low speed wind tunnel was modified by using a worm gear pair based on the split worm technology.The principle and realization of the split worm technology are analyzed,and the static and dynamic tests of the modified angle of attack mechanism are carried out.The results show that the positioning accuracy of the angle of attack and the quality of the test data are improved by using the angle of attack mechanism with split worm technology,which lays a good foundation for the follow-up test of the wind tunnel.
