Study on Vibration Character istics of Laser Leveler Installed on a Tillage Machine in Paddy Field
摘要
Abstract
Laser leveler installed on a tillage machine in paddy field means the development direction of agricultural e -quipment .The accuracy improvement of laser signal receiving is one of the key factors for its popularisation .In this pa-per , the factors which influnced laser signal receiving accuracy were analysised on the basis of the characteristics of mul -tifunction tillage machine .Laser leveler installed on a tillage machine was the coupling of free vibration and forced vibra -tion which drove the the laser receiver fixed on stand bar swing .Firstly,the model of vibration isolation system was built based on the kinetic equations and four-pole parameters theory .Secondly , fuzzy optimization method was used to optimize the vibration isolation system .Thirdly , according to the system model , the structure desgin of vibration isolation system was achieved.Finally,a test was designed to verify the vibration isolation system upon vibration test stand .The prediction results showed that the vibration isolation system was reliable to laser leveler installed on a tillage machine .The lateral amplitude of the receiver was less than 6mm,and the swing angle of the supporting rod was reduced from 25 to 2 degrees.关键词
