Chassis is the main structural component of an automobile, which is subjected to the full weight load being suspended. In the process of moving, the vehicle can both move and cut the tree while moving and sweeping the garbage as well as moving water. During the operation,the chassis is subject to dynamic loads depending on the driver and road conditions. The variation of dynamic loads causes fatigue failure to reduce the life of the chassis. Therefore,the determination of dynamic loads as input for chassis durability problem is necessary. This paper presents the research results on the determination of dynamic loads from the road surface acting on the chassis of multipurpose forest fire fighting vehicles by experimental methods. Experiments are performed when vehicles are moving on forest roads, under the actual working conditions of the vehicle.
