Evaluation of elastic shaft dumping ratio for the research of dynamic processes in transmission

Chuprynin Y.V., Kotov A.V.

Abstract

A method of evaluation of elastic shafts dumping ratio is presented. It involves a procedure of preliminary calculation of dumping ratio according to the mass and geometric characteristics of the shaft and the damping coefficient of shaft material, as well as a procedure of experimental correction of previously calculated values. The introduced approach allows to find the dumping ratios of transmission elastic shafts with sufficiently high precision.

Calculation of driving power of rotary blade tool of a tiller

Akimov A.P., Konstantinov Y.V., Fiodorov D.I.

Abstract

A method of calculation for the moment of soil resistance to the rotation of rotary blade tool depending on an angle of rotation and on the maximum drive power is developed on the basis of suggested mathematical model of interaction of tool with the soil. This method allows to simplify the experiments on determination of power characteristics of the tool and to reduce their amount considerably. Due to the community of basic points the offered technique can be basically transferred on other rotary tools.
