| 为解决履带式联合收割机底盘在丘陵山地田间进行机械作业时遇到的行驶通过性及稳定性问题，以自主研制的4LZ-4.0丘陵山地藜麦联合收割机底盘为研究对象，对其纵向和横向爬坡过程进行理论分析，计算出影响该履带收割机底盘正常爬坡的临界参数，同时利用RecurDyn建立该履带收割机底盘的多体动力学仿真模型并分析其爬坡性能，得出该履带收割机底盘适用于丘陵山地纵向和横向坡地的相关运动参数，并对该履带收割机底盘进行爬坡田间试验，校验仿真模型的可靠性。仿真结果表明，收割机在黏土路面行驶时，纵向上坡极限坡度角为30°，纵向下坡极限坡度角为30°，横向极限坡度角为5°。田间试验结果表明，收割机纵向最大爬坡度为28°，横向最大爬坡度为5°，试验结果与仿真分析结果之间相对误差为6.67%，吻合度较好。试验验证了收割机底盘动力学模型的可行性，可为丘陵山地藜麦机械化收获提供理论参考。 |

| 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. |
