Analysis and evaluation of vibration characteristics of a new type of electric mini-tiller based on vibration test

Abstract: Now the internal combustion engine mini-tiller has become the main and indispensable agricultural machinery in vast hilly and mountainous areas of Southwest China. However, its intense vibration may pose a big threat to operators. As a countermeasure to the tiller vibration, a new type of electric mini-tiller powered with a group of lithium battery and a brushless DC motor was developed. The vibration signals at the handle of the tiller were tested under 6 conditions as follows: the tiller was under states of … Show more

“…The natural frequency is a unique property of the material itself and is related to its own stiffness, mass, and other properties. Reducing the vibration frequency in mechanical structures and preventing resonance have become increasingly important in ensuring the service life of electromechanical components [31][32][33] . To avoid resonant phenomenon caused by the same frequency occurring between natural and external excitation frequencies after the structural optimization, fixed constraints are set after mesh division in ANSYS.…”

“…GB/T13441.1-2007 was equivalent to adopting this international standard. According to the "Mechanical vibration and shock -Evaluation of human exposure to whole-body vibration -Part 1: General requirements" a set of vibration evaluation systems for the whole rice transplanter was designed using the weighted root mean square acceleration method [14][15][16][17] .…”
