Multi-purpose forest fire fighting vehicle is produced in Viet Nam include a combination of fire fighting equipment such as high-pressure water pump, create corridor fire insulation cutting machine, vacuum and high wind speed bowling machine, extinguish the fire sand blast apparatus that is mounted active three axles vehicle. The paper presents how to determine the dynamic load acting on the chassis by 3D modeling method. The results of this study are the input parameters for assessing the durability of the chassis of multi-purpose forest fire fighting vehicle.
