Vibration Analysis on the Rack of Electric Mini-tiller

Abstract

Abstract The conventional internal combustion mini-tiller is a vitally agricultural tool with multiple functions, meanwhile the strong vibration may impose damaging effect on the user’s health. Hence, it is inevitable to replace the internal combustion by the electric motor. Although the performance of the electric mini-tiller has been enhanced greatly, the remaining vibration is still distinct and some diseases can be occurred incontrovertibly. The rack is one of the most significant components to connect the different parts for the electric mini-tiller, and the index may be improved through redesigning the structure of rack. In this study the rack has been analysed under different structure by Ansys workbench software, and simulations show that the vibration acceleration from the rack to the human body decreases greatly after the structure had been redesigned, which signifies the handling stability and riding comfort of mini-tiller can be promoted without the extra cost. Although the total vibration acceleration is reduced a lot, the vibration of cutting roller is more distinct than that of before. Therefore, the cutting configuration is needed to be optimized, and vibration transmitting path of cutting roller should be intervened as well in the future, enhancing the handling comfort and energy conservation of electric mini-tiller.
