摘　　要：在现有风洞研究的基础上,为了改变风速调节机制,本文提出一种新型L型双动力风速标准装置。同时,基于ANSYS workbench有限元仿真技术,对关键部件进行模态、结构强度分析,优化设计方案,并进行试验验证。结果表明:高风速>5m/s时,辅助风机的开启一定程度上增大了试验段流场流速,但不显著;低风速下,启动辅助风机可实现全域测量,且试验段流场的流速与辅助风机转速呈正相关,即会随转速的增大而增大。On the basis of the existing wind tunnel research,a new L-type dual dynamic wind speed standard de-vice is proposed in order to change the wind speed regulation mechanism.At the same time,based on ANSYS work-bench finite element simulation technology,the modal and structural strength analysis of key components was carried out,the design scheme was optimized,and the test was verified.The results show that when the high wind speed is more than 5m/s,the opening of the auxiliary fan increases the flow field velocity in the test section to some extent,but not significantly.At low wind speed,starting the auxiliary fan can realize global measurement,and the velocity of the flow field in the test section is positively correlated with the speed of the auxiliary fan,that is,it will increase with the increase of the speed.
