The given work is devoted to the study of dynamic loads acting upon a combine harvester, which is one of the most vibration-loaded types of modern transport and technological machines. The results on the evaluation of dynamic loads and ride quality parameters of a self-propelled combine harvester when driving along gravel and bituminous surfaces under various operating conditions are presented based on complex experimental studies carried out with the help of tensor and vibrometry methods. The method and conditions of measurements are given. On the basis of the experimental studies, the acceleration spectrum on the main parts of the combine harvester are presented and their description is given. Using the methods of spectral analysis and statistical processing, a vibration modal analysis has been carried out during a combine harvester movement. According to the results of the analysis, the basic vibrational modes have been determined, and it has been shown that the self-propelled combine harvester movement dynamics is determined by vertical and longitudinal-angular vibrations of its core on pneumatic tires. Further scientific research directions to improve the ride quality and to decrease the dynamic loads on a considered class of self-propelled agricultural machines have been determined.
