Tools for Automating the Calculation of Hydraulic Actuator Parameters

Abstract

The article addresses the problem of improving the efficiency of hydraulic system design by automating the calculation of key parameters of hydraulic actuators, which are essential components of volumetric hydraulic drives used in both mobile and stationary machinery. It is noted that the correct selection of the actuator type and its parameters directly influences the overall efficiency of the hydraulic system. Traditional calculation methods, which rely on manual or semi-manual operations, require considerable time and are prone to errors.

The aim of the study is to develop a software tool that automates the calculation process of hydraulic actuators based on specified operating characteristics and ensures accurate and rapid computations. The article describes calculation algorithms for hydraulic cylinders (linear motion) and hydraulic motors (rotary motion). For hydraulic cylinders, the methodology includes determining the piston area, calculating the piston and rod diameters, and checking stability. The calculations take into account technological load forces, working chamber pressures, friction forces, and other influencing factors. For hydraulic motors, an algorithm is presented for determining the displacement based on the known torque and pressure, enabling precise parameter selection for the optimal motor type.

The developed computer program implements these algorithms as an interactive application that can be used both in the educational process (e.g., during coursework and thesis projects) and in industrial settings. The program features a user-friendly interface, contains a set of reference data, helps avoid common errors associated with manual design, and is useful for engineers, educators, and students. This development supports the digitalization of calculation processes in the fields of hydraulics and mechanical engineering, aligns with the requirements of modern engineering education and practice, and contributes to improving the quality of technical solutions in design.
