Test method for testing vehicle simulation driving resistance through drum test bench

The invention discloses a test method for testing vehicle simulation driving resistance through a drum test bench, and belongs to the technical field of whole vehicle test. Comprising the following steps: S1, carrying out vehicle inspection; s2, a vehicle is fixed, and a balancing weight is installed; and S3, the vehicle slides, and a simulated driving resistance coefficient is generated. Furthermore, S26, the test vehicle is provided with a balancing weight according to the quality requirement of the expanded vehicle model. According to the test method, the vehicle mass is increased through the vehicle counterweight on the basis of the drum system, the drum simulates sliding of the driving resistance, the same vehicle type has different vehicle mass sections, for example, trucks, boxcars, sanitation vehicles and the like are special vehicles with the same chassis and the same engine assembly, and in the vehicle types with the different mass sections, the vehicle mass sections of the trucks, the boxcars, the
