切割器是甘蔗收获机的重要部件 ,其动态性能直接影响到收获机的工作性能。在收获作业时 ,切割器高速旋转 ,由于甘蔗生长密度不等、茎杆粗细不匀 ,切割器入土切割工作条件相当恶劣 ,致使切割器结构承受很大的冲击负荷与随机激励 ,影响收获机的整机性能。因此 ,对切割器结构进行动态设计 ,按一定的原则不断调整结构设计参数 ,进而改善结构的动态性能 ,对于甘蔗收获机设计具有重要意义。
The cutter is an important part of the sugar cane harvester and its dynamic performance directly affects the performance of the harvester. In the harvesting operation, the cutter rotates at a high speed. Due to the uneven growth density of the cane, the thickness of the stem is not uniform, and the cutting and cutting work conditions of the cutter are rather poor, which causes the cutter structure to bear a great impact load and random excitation, Machine performance. Therefore, the dynamic design of the cutter structure, according to certain principles continue to adjust the structural design parameters, thus improving the dynamic properties of the structure, for sugarcane harvester design is of great significance.
