Abstract:
      To solve the problems of running ability and stability of the chassis of the crawler combine harvester during mechanical operation, this study took the self\|developed 4LZ-4.0 hilly and mountainous quinoa combine harvester chassis as the research object and examines the climbing performance of the crawler harvester chassis. Firstly, the processes of longitudinal and lateral climbing of the crawler harvester chassis were analyzed theoretically. The critical parameters influencing the normal climbing performance of the crawler harvester chassis were identified, analyzed, and calculated. Secondly, the multi\|body dynamics simulation model of the crawler harvester chassis was established by using RecurDyn and its climbing performance was analyzed. The relevant motion parameters of the crawler harvester chassis suitable for longitudinal and lateral slopes in hilly and mountainous areas were obtained. Finally, the climbing field test of the crawler harvester chassis was carried out to verify the reliability of the simulation model. The simulation results indicated that when driving the harvester on a clay road surface, the maximum longitudinal uphill slope angle was 30°, the maximum longitudinal downhill slope angle was 30°, and the maximum lateral slope angle was 5°. The field test results showed that the maximum longitudinal climbing degree of the harvester was 28°, and the maximum lateral climbing degree was 5°. The relative error between the test results and the simulation analysis results was 6.67%, and the coincidence degree was good. The test verifies the feasibility of the harvester chassis dynamics model. This study can provide a theoretical reference for mechanized harvesting of quinoa in hilly and mountainous areas.
