Abstract: In order to test the adaptability of a domestic military off-road vehicle in high temperature (dry heat) area. Thermal balance capacity test, ventilation and heat insulation capacity test, air-conditioning refrigeration system performances test, self rescue and mutual rescue test, and adaptive driving test were carried out in Turpan area. The maximum allowable ambient temperature of the sample vehicle is 46.2 ℃; the thermal insulation performance is good but the ventilation performance is relatively sultry; the temperature difference between the shoulder of the rear passengers and the outside of the vehicle is 8.2 ℃ after 20 minutes of refrigeration at 41.5 ℃; self rescue and mutual rescue can be realized on the desert ground; no fatal fault and serious fault in the 3 000 km adaptive driving test. The test process was described and the test results were analyzed to provide basis for the design and finalization of the vehicle type, and the vehicle was classified according to the test process and product characteristics The high temperature test of similar automobile enterprises provides technical reference and reasonable suggestions.
