Abstract

The aim of the presented article is to verify the automatic and manual operating mode of the proposed measuring device for loading the external circuit of the working hydraulics of the tractor in the simulation program FluidSim. Before starting the simulation, it is necessary to select the individual parameters of the tested hydrogenerator UD 20, which is specified by the manufacturer, and to create a simulation model of this device according to the design. The device allows measurements to be made in automated mode by means of an electro-hydraulic proportional valve and in manual mode by means of a throttle valve. In the simulations in both operating modes, the flow rates at increasing speeds and constant pressures from the simulations were compared with the data provided by the hydrogenerator manufacturer. By comparing the data, it is possible to see negligible percentage differences, which are caused by the increasing temperature of the working fluid and the internal resistance of the hydrostatic transducer and filter. From these findings it follows that the proposed electromechanical device meets all the specified requirements and during real operational tests of the tractor hydraulics, its function will be correct.
