PURPOSE:To reproduce the state approximate to the state of a truck traveling actually in the rain by placing a cab on a stand, and spraying water from above and front and blasting air from front while giving parallel, longitudinal or vertical motion alternately on the right and left. CONSTITUTION:When water is fed to pipings 13... by driving a pump, the water injected from spray nozzles 12... is sprayed to the front, above, both right and left sides and lower side of a cab 10. Thence, air is blasted to the front of the cab 10 by driving a blower 15. The direction, flow rate, etc. of the wind can be regulated by a distributor 14. On the other hand, an oil hydraulic motor 18 is started to give the motion similar to that during traveling of a truck to the cab 10. While the cab 10 in a test chamber 1 is given parallel or vertical motion alternately on the right or left side, and during this time, it is sprayed with water from the front, above, both right and left, and lower side, and the air is blasted thereto from the front at the proper direction and flow rate of the wind; therefore, it is put in the state proximate to the state of the truck traveling in the rain. |
