Vibration Measurement and Vibration Reduction of Steering Wheel of an Agricultural Tractor

A tractor is a vehicle specifically designed to deliver a high Torque at slow speeds, for the purposes of hauling a trailer used in agriculture. Steering wheel vibration is major concern in determining the operator comfort in agricultural tractors. Any engineering system possessing mass and elasticity are capable of relative motion. When this motion repeats after a given interval of time, then this motion is known as vibration. In many cases it is undesirable and is a form of wasted energy. This is particularly true in tractors and farm machinery as they generate noise, break down parts and transmit unwanted forces and movements to different components. Vibrations and noise in tractor are generated due to rotating and reciprocating parts, vibrations in engine components, exhaust gases and flow of hydraulic fluids. In this paper, we deal with the reduction in vibration of steering wheel of an agricultural tractor by providing isolation. Isolation makes use of materials and mechanical linkages that absorb and damp these mechanical waves. Also the vibration in steering wheel is measured experimentally and also by using software.
