Embodiment 1
[0059] Since the existing standard model of automobile aerodynamics can achieve functional limitations and cannot meet the needs of multi-physical quantity measurement, the present invention provides an "intelligent" standard model of automobile aerodynamics with "perception" function, that is, CAERI Aero Model. In this embodiment, the standard model includes the car body 1 (including the head part 101 , the body part 102 and the rear part 103 ), a back module, a chassis and an engine compartment arranged on the head part 101 of the car body 1 .
[0060] For car body 1, as attached figure 1 ~ attached figure 2 As shown, the volume of the car body 1 is three quarters of the whole car, the car body 1 does not have a back module, and the car body 1 is provided with an air intake grille 13, a replaceable rearview mirror module 2 and a detachable engine compartment cover; if attached image 3 As shown, the back module is provided with six conical positioning blocks, and the cen...
Embodiment 2
[0065] The only difference from Embodiment 1 is that it also includes a pressure measuring sheet 17, a pressure scanning valve sensor, a cobra probe, an airfoil angle sensor, a temperature and humidity sensor, an acceleration sensor, a five-hole probe, and a laser range finder 19 . The pressure measuring piece 17 is arranged on the upper surface of the car body 1, and the pressure scanning valve sensor is arranged inside the car body 1, and the pressure scanning valve sensor is used to measure the pressure distribution on the surface of the car body 1; the cobra probe is arranged on the engine hatch sensor On the upper surface of the arrangement area, the cobra probe is used to measure the air turbulence; the airfoil angle sensor is arranged on the upper surface of the front sensor arrangement area, and the airfoil angle sensor is used to measure the airflow angle; the temperature and humidity sensor is arranged on the top sensor arrangement area, The temperature and humidity s...
Embodiment 3
[0067] The only difference with Embodiment 1 is that the back module is a sedan type, as attached Figure 17 As shown, the conventional wind resistance test can be carried out: there is no need to install other sensors, and the standard model can be fixed on the wind tunnel force balance. Specifically, make a 1:1 model for a full-scale wind tunnel test, or make a scale model for a scaled-down wind tunnel test.
