Some statistic indices of functioning of sowing unit with elastic-damping mechanism in tractor transmission

The experimental research results obtained by operating the sowing machine-and-tractor unit equipped with elastic-damping mechanism which changes transmission properties, makes it compliant and, therefore, absorbing vibrations of the external disturbing influences, are dealt with in this article. Several performances of a unit with more rigid transmission are given as a comparison. The given correlation functions and spectral densities of the process show an evident improvement of operating characteristics.
