摘　　要：本文在满足大景深、大视场和高精度的同时,利用现代光力学方法首次实现了汽车模型风截面的非接触、全场、实时测量,并研制出了具有独创性的“汽车模型风截面光学式实时测量装置”。对桑塔纳2000型轿车1/4模型进行了风截面测试,并将本文结果与德国斯图加特大学汽车风洞实验室中的结果进行了对比,由此证明该法是成功的。On the precondition of big field-depth, big view-field and high precision, it is the first that realize full-field, non-touch and real-time measuring of the head-on wind section of automotive models using modern optical mechanical method. ' A real-time checkout equipment for measuring the head-on wind section of automotive models using optical method' has been developed. The measured results for Santana 2000 model(1/4) in this paper agree very well with that of Stuttgart University of Germany.
