Разработка численных моделей для комплексного исследования напряженно-деформированного состояния элементов гидропередачи ГОП-900

Abstract

The paper describes the calculation schemes for mathematical modeling of elements operating in hydrovolume transmission (HT). Mathematical models are represented for determining of stress-strain state of some elements of hydraulic transmission: the HT housing, the block of HT distributor valves and their joint deformation. The software for the joint solution of several specialized tasks is created: the evaluation of t he efficiency of the HT, the automatic constructionand preparation of the computational models of the HT elements for given parameters, the optimization of structural and geometric parameters of the HT elements by the criteria for efficiency of the hydrovolume transmission. With the help of the developed software, a rational form o f the internal geometry of the working channels of the block of trunnion distributors (BTD) of the HT is found, whi ch ensures strength and rigidity of HT BTD, and simultaneously reduces the power losses during the operation of hydrovolume transmission.
