    摘要: The present invention provides a method for improving the fireproofing performance of vehicle body, including: assuming a combustion position and hazards and defining a combustion damage area of vehicle body model according to 3D model and strength weak area of the vehicle body; calculating deflection of vehicle at a predefined high-temperature load charged onto the combustion damage area by using strength finite element; and judging whether the space between a suspension member under the vehicle and track surface can meet the requirement of travelling capacity under a safe speed after the vehicle is deflected according to the deflection of vehicle or not; if not, performing a fireproofing treatment to the combustion damage area of vehicle body. With little cost of calculation and non-metal materials, the present invention could improve strength performance of thermal load of the metal vehicle body, thus reducing the fire hazards and meeting the requirement of travelling capacity; in the case of any fire hazard, it's possible to win more time for evacuation and rescue, so as to guarantee the personnel safety and minimize the loss of properties.
