Tractor Seat Vibration optimization with Active Control System during Tillage using Modelling and Simulation in Ansys.
Keywords:
Tractor Seat, Tillage Equipments, Vibrations, Controller, SimulationAbstract
Most of the tractors are without suspensions and tractors have to operate for many hours in fields for soil preparations for crop production. The frequency of vibrations which is most harmful to humans is in the range of 4-6 Hz. This article is to adopt modern approaches to reduce the vibrations at tractor seat to improve the comfort levels. Real time seat accelerations were measured at seat base using tri-axial accelerometer at three different forward speeds of tractor and using different type of tillage equipments. Model of tractor seat was created and has been analysed in Ansys for total deformation and random vibrations. PID and Fuzzy-PID controllers were designed in MATLAB and the tractor seat was modified by installing electronic damper and tested for improved results. Results shows that vibrations accelerations were reduced to notable values to improve the comfort level of tractor operator.
