Results of experimental studies of an agricultural tractor with an elastic-damping mechanism in a power train

Abstract

Improving the operational efficiency of agricultural tractors is one of the main factors that helps to increase productivity while significantly reducing energy costs. The developments that are associated with improving the design of power transmissions for wheeled agricultural tractors are very important, because its indispensable condition is to increase labor productivity in agricultural production. Achievement of the required characteristics of agricultural tractors is determined by the properties of the power train and the interaction of associated systems. One of the main qualities of a power train should be the ability to absorb torsional vibrations and damp the load.

The article presents studies of the constructive improvement of the power transmission of an agricultural tractor by installing a developed elastic-damping mechanism using the example of a tractor of a small traction class. Considering the relevance of the topic, the article solved the problem of determining the influence of the elastic-damping mechanism installed in the power transmission of the tractor on its operation with the cultivator.

The paper analyzed the cross-correlation function and the mutual spectral density of two processes: the angular speed of rotation of the crankshaft of the engine and the angular speed of rotation of the drive wheel, which showed a change in the speed of propagation of passing frequencies of load oscillations along the shafting and displacement of the frequency of disturbing influences.
