ABSTRACT:
A snow-weathering test apparatus for a self-propelled vehicle, comprises: a low-temperature testing chamber; a water-spraying unit provided with a truck having a wheel, on which truck is mounted a two-fluid injection nozzle for spraying water with an air-jet into a mist, which water-spraying unit is movably provided in the low-temperature testing chamber; a cooling unit provided with an air-feed duct connected between the low-temperature testing chamber and the cooling unit to feed a cooling air issued from the cooling unit to the low-temperature testing chamber; an air-return duct connected between the low-temperature testing chamber and the cooling unit to permit the cooling air to return to the cooling unit from the low-temperature testing chamber; and a snow-catching unit provided with a heating unit, for catching a snow carried by the cooling air from the low-temperature chamber, which heating unit is employed to melt the snow caught by the snow-catching unit.
