Abstract

The electric mini-tiller can produce extra vibration during tilling, shortening the span life of components and undermining manipulator’s body. Therefore, sensors are set in the electric motor and armrest, and field experiments under different conditions have been accomplished. Test data show that some of the vibration frequency bands of electric mini-tiller are sensitive to the human, imposing great harm on people’s health. So redesigning the electric one to lessen or cut off the vibration transmission is an urgent engineering problem.

电动微耕机在作业过程中会产生较为明显的振动，既缩短了零部件的寿命，也给操纵者的健康带了巨大的伤害。在微耕机的电动机和扶手处设置了传感器，进行了不同工况下的田间实验。数据表明微耕机部分振动频率接近人体的敏感频段，因而对人体的影响较大。因此，如何对微耕机的结构进行全新设计，进一步减小和切断电动机和刀具的振动传递是亟待解决的工程问题
