Abstract

The invention relates to a model analysis method and system for an internal flow field of a hydraulic distance changer. The method comprises the following steps: S1, making a three-dimensional model of a working impeller of the hydraulic distance changer; S2, according to the three-dimensional model of the working impeller, establishing a full flow channel geometric model of the torque converter;3, carrying out mesh processing on that geometric model of the whole flow channel of the torque convert to obtain a mesh model; S4, setting and simulating the basic parameters of the mesh model to obtain a preliminary model; S5, setting dynamic parameters of the preliminary model and coupling the dynamic parameters with the preliminary model to obtain a dynamic model; 6, carrying out pressure field analysis and velocity field analysis on that dynamic model, obtaining a simulation value, and calculating a simulation efficiency value through the simulation value. This method can accurately findout the factors that affect the transmission efficiency of torque converter flow field, so as to deepen the analysis and understanding of the characteristics of the flow field.

Description

technical field [0001] The invention relates to the field of analysis of the internal flow field of a hydraulic pitch changer, in particular to a model analysis method and system for the internal flow field of a hydraulic pitch changer. Background technique [0002] In recent years, due to the development of computer technology and testing technology, a large number of researches have been carried out on the flow field in the torque converter by using numerical simulation technology and test technology at home and abroad, mainly including three aspects: flow theory, numerical simulation and flow field test. Flow theory is a theoretical method for flow field design and analysis, mainly including one-dimensional flow theory, two-dimensional flow theory and three-dimensional flow theory. The numerical simulation adopts the method of three-dimensional transient numerical simulation calculation, so it can predict the real movement of the liquid flow more accurately. [0003] At ...
