The influence of the frequency vibration of traction load on rolling resistance of the wheeled tractor
In the article there are given dependences received experimentally of the resistance force to rolling of a wheel tractor on the change of load vibration frequency on a hook on different surfaces. It is shown that the deformation size changes significantly having an impact on the soil resistance to compression and displacement under the oscillating character of efforts application in the contact place of the wheel with soil. It is stated that the oscillating character of changes of traction resistances of agricultural machines and implements causes oscillations of the tangential force of traction on the leading wheels of the tractor. It is established that with the growth of the frequency and amplitude of oscillations of traction resistance the frequency and amplitude of oscillations of the tangential force of traction is proportionally increases. It is noted that the most important task in the agricultural production is raising the efficiency of using machinery-tractor aggregates. All kinds of agricultural works are characterized by an irregular charging of the tractor and occurrence of large loading.
