Abstract

PURPOSE:To make it possible to quantitatively evaluate the adhesion of a contaminant, by a method wherein a test sheet reacting with a tracer is mounted to the surface of the car body of the vehicle arranged in a wind tunnel and the surface of the car body is allowed to receive an air stream from the front and the surface contaminant of the car body is judged by the reaction of the tracer scattered from the vicinity of wheels with the test sheet. CONSTITUTION:A vehicle 3 is arranged in the wind tunnel 1 of a system and the air stream A from a blower 4 is allowed to flow to the vehicle 3 from the front thereof to the rear thereof. A test sheet 11 reacting with a tracer is adhered to the surface 10 of the vehicle. A plurality of tracer supply nozzles 6 are mounted to the lower surface of the tire house 5 in the vicinity of wheels 9 and a tracer generator 8 is connected to the nozzles 6 through a tracer supply hose 7. The vehicle 3 is made equivalent to a predetermined operation state in the wind tunnel 1 and reaction generated when the tracer scattered from the nozzles 6 has been adhered to the test sheet 11 is investigated and the state of the contaminant on the surface 10 of the vehicle is quantitatively judged to obtain the planning data of a new vehicle.

(Industrial Field of Application) This invention is designed to reduce dirt on people's faces inside vehicles due to mud splashing.
This paper relates to a method for evaluating dirt adhesion on the surface of a car body. (Prior Art) Conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 57-18/'1944, a test device equipped with j÷llll11;
However, this device is only capable of spraying one gun into the interior of the vehicle, and it is not necessary to use this device to evaluate IJ stains on the surface of the vehicle body. For this reason, conventionally, in order to evaluate the dirt (Jf'i) in the above example, for example, a wide running test using a prototype vehicle (
If the car is not running, judge by looking at the surface of the car's body, or take a photo of the car after the 71-row. A method was used to visually determine the amount of dirt adhering to the surface of the car body.However, in the conventional +'; In addition, when the above-mentioned dirty shield situation requires shape modification, the cost of shape modification becomes expensive and the development efficiency of the vehicle is significantly reduced. (Eleventh aspect of the invention) This invention determines the contamination resistance by a simple method using a test sheet that reacts to a laser. In addition, Hatsutomo Monko's clay [7' rule (clay model car)]
Now, if you are going to do the test, you can easily straighten the shape of the 4-stone I to 5-. EJ ”6 i,'P
! The ljl component of the dfi/J method is treated as 141 targets. (Structure of the Invention) This invention is a method of installing a test sheet (-i LJ) on the surface of the cow's body of a vehicle that is installed in a wind tunnel and receiving air flow from the front, and that is opposite to the tracer (-i LJ).
