Abstract
One of the effective ways to increase productivity and reduce specific fuel consumption in agricultural production is the use of machine-tractor aggregates (MTA) based on modular power units developed in Ukraine. The modular power unit (MPU) consists of power and technological modules. The power module (PM) is a tractor whose nominal traction effort amounts to 14–16 kN. The technological module (TM) is an additionally connected axle with a wheel drive activated from the PM ground-speed power take-off shaft. In a horizontal plane, the power and technological modules are connected with the alpha hinge, equipped with a hydraulic cylinder. Its bottom-end and head-end are connected by a hose with a damper inboard. The damper is in the form of a washer with a hole of diameter d. It was revealed that the influence of this parameter on coefficient of the damper washer hydraulic resistance (Km) is described by a parabolic law \(K_{m} = 0.25 \cdot d^{2} - 0.36 \cdot d + 1.67.\) The use of the parabolic law proves that for satisfactory stability and controllability of the modular MTA movement, a damper washer with a hole of a diameter not exceeding 2.2 mm should be inserted into the hose connection which links the bottom-end and the head-end of the MPU hydraulic cylinder.
