Development of methodologies and software for engineering, simulation and optimization of oil-hydraulic cylinders of large measurements and strengths
This paper features reaserch conducted in the area of processing systems and production processes of oilhydraulic cylinders of large measurements and strenghts, as specific hydraulic components in the area of fluid transmission of power, especially important in the functioning of hydroenergetic objects. The fundamental basis in the development of oilhydraulic cylinders of large measurements and strenghts lies in experimental research and mathematical modelling of non-stationary, highly dynamic hydraulic processes in the cylinder and thrust duct. Establishing stability of stipulated quality of vital positions in the set of these products (ducts and connecting rod) is a difficult task for engineers and technologists since these are products with high reliability. High technoeconomic effects in this field are especially pronounced in frequent cases of reparing these products after damage of work surfaces during long years of the exploitation period. These were sufficient reasons to approach the development of methodologies and software for engineering, simulation and optimization of oil-hydraulic cylinders of large measurements and strengths. Thanks above all to the company Prva Petoletka PPTCilindri, AD-Trstenik, Serbia, one of the leading manufacturers of hydraulic cylinders at large, additional experimental research was made possible for us. The conducted research enabled the application of new methods of engineering processing systems and processes located on the production of vital positions of these products (ducts and connecting rod) by the honing procedure as the most efficient manner of work surface finishing treatment. Based on usage of experimental research results and mathematical modeling results, with the development and application of method for identification of unknown parameters of the mathematical model, certain vital parameters of hydraulic cylinders of large measurements and strenghts were determined with sufficient precision. The desired aim was attained, that new scientific knowledge be applied in this complex area and the basis for high efficiency provided in achieving desired conformity of product quality (accuracy of measurements and roughness of treated surfaces).
