摘要/Abstract

摘要： 针对小型整杆式甘蔗收获机现场作业过程中出现的破头率高、切割质量不稳定、刀盘振动大等问题,采用位移与加速度传感器对刀盘及振源处振动信号进行数据采集与分析,得出不同测试点位振动强度对刀盘连接处的刚性影响程度。结合振动测试系统,并将采集的数据进行快速傅里叶变换,测得影响刀盘振动的主要频率。综合考虑收获机切割质量、稳定性因素,对刀盘、剥叶器、车架、齿轮箱的装配提出优化设计方案,可为小型整杆式甘蔗收获机的改良提供参考依据。

Abstract: The problems in the field operation of the small whole stalk sugarcane harvester were considered, such as high rate of broken head, unstable cutting quality and large vibration of cutter head. The displacement and acceleration sensors were used to collect and analyze the vibration signals of cutter head and vibration source. Therefore, the influence degree of vibration intensity of different test points on the rigidity of cutter head joint was obtained. Then, combined with the vibration test system, the main frequency of cutter head vibration was measured by FFT. Finally, considering the cutting quality and stability of the harvester, the optimal design scheme for the assembly of cutter head, leaf stripper, frame and gearbox was proposed. It could provide reference for the improvement of the small whole stalk sugarcane harvester.

Key words: small whole stalk, sugarcane harvester, vibration, FFT, optimal design
