Development of a rational model range of hydrodynamic torque transformers based on their key parameters: method

Abstract

Introduction (problem statement and relevance). The existing methods for development of a model range of hydrodynamic or hydraulic torque converters do not consider characteristics of devices operating together with such converters. Consideration of characteristics of internal combustion engines and gearboxes will allow development of a more rational model range of hydrodynamic torque converters.The purpose of the study is to develop a method for building a model range of hydrodynamic torque converters taking into account characteristics of devices operating together with such converters.Methodology and research methods. Based on the analysis of parameters characterizing a hydrodynamic torque converter and of the existing model ranges, key parameters have been selected. To select estimated figures and parameters, mathematical statistics elements have been used.Scientific novelty and results. The method has been developed that allows keeping and using advantages of the known methods and eliminating a number of their disadvantages. The advantage of the proposed method consists in consideration of characteristics of internal combustion engines and gearboxes assumed to be used, which will allow, using the optimization process, definition of rational key parameters of hydrodynamic torque converter models. Based on the proposed method, a computer application program has been developed for estimation of rationality of key parameters of hydrodynamic torque converters of a model range.Practical significance. It makes sense to use the proposed method when developing model ranges of hydrodynamic torque converters.
