摘要

在风速为250公里/小时的风洞中测量全尺寸汽车的声学和空气动力学特性，需要一个足够坚固的穿越系统，以承受气流而不影响测量精度;足够的空气动力，以减少自身噪音对测量的影响;定位测量仪器精度高。这里介绍的安装在斯图加特大学的穿越系统，通过结合激光和计算机技术、空气动力学和传统的高精度机械工程来满足这些要求。

Traversing system for full-scale wind tunnel

Measuring acoustic and aerodynamic properties of full-scale automobiles in a wind tunnel with a 250 km/h airstream demands a traversing system that is rigid enough to withstand the airstream without affecting measurement accuracy; sufficiently aerodynamic to reduce the effects of own noise on measurements; and highly accurate in positioning measurement instruments. The traversing system described here, installed at the University of Stuttgart, meets these requirements by combining laser and computer technology, aerodynamics and traditional high-precision mechanical engineering.
