摘　　要：传统的联合收获机振动控制方法主要是基于操作人员相关经验进行技术分析,工作效率较低,减振效果不显著。针对以上问题,提出了一种新型履带式联合收获机振动控制方法,以发动机和切割结构为研究对象,根据切削结构的受力分析结果和结构动力学分析结果,得到各作用力和力矩,计算求解质量分布位置和质量的最优组合方案,进而解决自走式联合收获机切削结构的振动问题。根据振动理论和现代设计方法,通过模型分析和有限元计算,建立联合收获机发动机的减振模型。田间试验结果表明:提出的模型能够有效改善履带式联合收获机的振动状态,作业时联合收获机振动水平降低45%~76%。The traditional vibration control method of combine harvester is mainly based on the technical analysis of the operator's relevant experience,so the efficiency is low and the vibration reduction effect is not significant.In response to the above problems,this study proposes a new vibration control method for crawler combine harvester,based on the en-gine and cutting structure as the research object,based on the results of force analysis and structural dynamics analysis of the cutting structure,and then obtain each force and moment,calculate and solve the optimal combination of weight dis-tribution position and mass,and then solve the vibration problem of the cutting structure of self-propelled combine har-vester,based on vibration theory and modern design methods,the vibration control of combine harvester engine is estab-lished through model analysis and finite element calculation,and vibration damping model is established.The field test results show that the model proposed in this study can effectively improve the vibration state of the crawler combine har-vester,and the vibration level of the combine harvester is reduced by 45%~76%during field operation.
