Dynamic characteristics of a tractor cabin during plow tillage and rotary tillage

Due to the environment of irregular soil characteristic for agricultural fields, dynamic characteristic occurs in the tractor cabin during agricultural operations.Operator's fatigue is increased, and operation performance is decreased by these irregular environment conditions.This study was conducted to measure and analyze the dynamic characteristic of a tractor cabin, a major agriculture machinery, during agricultural operations.The specification of tractor used in the study was a 95 kW class tractor.To analyze the dynamic characteristics of the tractor cabin, the main agricultural operations, plow tillage and rotary tillage, were selected.To measure data of dynamic characteristic of the cabin, which continuously changes during operations, an Ellipse Series INS (inertia navigation system) with a built-in IMU (inertia measurement unit) was attached to the center of gravity of the cabin.During field test, the gear stages of plow tillage were B4 (4.3 kmh -1 ) and B5 (5.6 kmh -1 ), and the gear stages of rotary tillage were A3 (3.3 kmh -1 ) and A4 (4.2 kmh -1 ), which are the most commonly used.To analyze dynamic characteristic such as roll and pitch during operations according to the gear stages.As a result, the dynamic characteristics of pitch increased more than the dynamic characteristics of roll as the travel speed increased, and the dynamic characteristics of both agricultural operations were in the range of 2 to 5.
