The combine harvester has a complex work environment, and the reliability of the rack is critical to the functionality of the machine. In order to shorten the test time, reduce the cost of research and development, and make the road spectrum can be reproduced on the test-bed, this paper takes the combine harvester as the research object, the acceleration spectrum was measured on asphalt road, hard road in field and wheat field, and the multi-body dynamic equation was established according to the actual parameters of the vehicle. The transfer function between the tire displacement signal and the target signal is established, and the tire displacement spectrum is calculated. The road spectrum is taken as the input load of the four-column test-bed, and the actual load condition is reproduced on the test-bed, which provides the input condition for the fatigue analysis of the combine harvester rack in the later stage, and greatly enhances the efficiency of durability design.
