摘要

泛亚汽车缩比模型风洞于2018年12月份建成并投入运营，为汽车造型前期的空气动力学研究提供了有力的工具，是国内主机厂首个汽车缩比模型的专业风洞，也是世界上先进的汽车缩比模型风洞，将提升泛亚的整车气动性能开发能力。该风洞设计为40%的缩比模型风洞，采用3/4开口喷射的回流式流道。试验段采用双半径转台，使模型更加靠近高流场品质的喷口，并有效减小了试验段的空间；试验台可在±30°横摆角范围内旋转，用于模拟路面汽车的横向风影响；高精度的六分量测力天平保证了精确的气动力测试；天平系统上集成了五带路面模拟系统，其中中央移动不锈钢带用于模拟汽车行驶的路面相对运动并减少地面附面层影响，其他四带为聚合物，用于驱动车轮高速旋转。边界层移除系统包括近喷口地面处的一级水平抽吸、转盘前缘上游的二级抽吸以及转盘前的三级吹气口，用于有效控制地面附面层的影响。智能的移测及模型定位系统为流场测量和模型的快速移动提供了准确、快速的定位。通过调试和标定，风洞流场品质满足设计要求，轴向静压梯度、压力波动等性能指标好于其他同类风洞。与同济大学的上海地面交通工具风洞中心对标结果一致，偏差不超过1%。

Abstract

PATAC

Pan Asia Technical Automotive Center Co.

Ltd

reduced scale wind tunnel(RSWT) was constructed and came into operation in December 2018 which is a powerful facility for vehicle aerodynamic development at the early styling stage. It is the first professional automotive RSWT in domestic OEMs

and also an advanced vehicle RSWT in the world. It will promote PATAC's aerodynamic development capability on full vehicle performance. The wind tunnel (WT) was designed for a model scale of 40%. It is a 3/4 open jet

closed return the wind tunnel. The test section adopts double radius turntable

which makes the model close to the jet area of the nozzle and effectively reduces the space of test section. The turntable can be rotated within ±30° yaw angle to simulate the crosswind effects on road vehicle. The high-precision six-component force measuring balance ensures the accurate aerodynamic test. There is an integrated five-belt system inside the balance system. The center moving belt is a stainless steel belt which is used to simulate moving ground and reduce the influence of the ground boundary layer. Other four belts are polymers and used to drive the wheels at high speed corresponding to the wind speed. The boundary layer removing system includes the primary suction scoop at the nozzle exit

a secondary suction slot located just upstream of the turntable leading edge and the tertiary blowing slot on the front of turntable

which can effectively control the influence of the ground boundary layer. The intelligent traversing and model positioning system provides accurately and rapidly positioning for flow measurement and rapid movement of the model. By means of finally commissioning and calibrating

the PATAC RSWT flow quality and measured forces meet the specified requirements

and some parameters are better than other WTs for example longitudinal static pressure gradient and pressure fluctuation. The testing results coincide with those measured in Tongji WT with difference less than 1%.
