Abstract

A reshaping method of an automobile torque converter blade lattice system comprises the following steps: 1) acquiring geometric information of the existing torque converter blade lattice system; 2) calculating target inlet and outlet angles of blades and the inner and outer ring intersecting lines of a circulating circle; 3) entering a genetic algorithm program to start iterative computation; 4) randomly modifying each point coordinate to generate an initial group; 5) calculating the inlet and outlet angles of the blades and the inner and outer ring intersecting lines of the circulating circle after being modified; 6) judging the matching degree of the inlet and outlet angles of the blades and the inner and outer ring intersecting lines of the circulating circle after being modified with the target inlet and outlet angles obtained by calculation in step 2; and 7) if the matching degree is high, inheriting the individual to the next generation for further intersection and mutation to obtain point coordinate combination with higher matching degree; and if the matching degree is low, eliminating the individual. The invention has the advantages of modification of the existing torque converter CAD model, thus realizing the optimization of the torque converter.

Description

technical field [0001] The invention relates to a design method of an automobile hydraulic torque converter, in particular to a method for modifying the blade grid system of the existing hydraulic torque converter. Background technique [0002] The hydraulic torque converter is one of the key components of the automatic transmission system, and its performance has an important impact on the performance of the vehicle. Due to the complexity of the flow field in the torque converter, its design is basically based on a simplified one-dimensional beam model and empirical data for repeated trial production tests. The disadvantage of this method is that the error is large, the design cycle is long, and the optimal performance may not be achieved. Contents of the invention [0003] The invention provides a method to optimize the blade cascade system of the hydraulic torque converter by using the existing CAD model of the hydraulic torque converter. On the premise of retaining th...
