Description
Technical field
The present invention relates to a kind of design method of fluid torque converter.
Background technique
Fluid torque converter (hydraulic couplers) is the critical piece of automatic variable-speed drive system system, and the transmission performance that improves system, the Acceptable life that prolongs system are had important practical significance.Principal and subordinate's dynamic component of fluid torque converter (hydraulic couplers) is (bending moment operating mode, the coupling operating mode) that flexibly connects by its inner liquid-working-medium, the transmission system that fluid torque converter (hydraulic couplers) is housed has that adaptability is strong, the stepless torque changing speed change, start steadily, decay comes from the impulsive load of motor and terminal transmission device to greatest extent effect, it is first-class to be applied in medium-to-high grade car, urban bus, engineering machinery, oil drilling and r eoovery machine, railway locomotive widely.In China present stage, the use of fluid torque converter (hydraulic couplers) is in the stage of popularizing, and the research and development of carrying out fluid torque converter (hydraulic couplers) have reality and long-range meaning.
Along with the develop rapidly of computer, especially recent years software and hardware fast development, be based upon on the CAMM/CAD/CAM/CAE hardware and software platform the so-called reverse-engineering that realizes " product-design-product ", be up-to-date a kind of machine design method.This is a kind of effective ways very practical, that really can develop, develop product fast, for developing high performance fluid torque converter (hydraulic couplers) at short notice reference is arranged very.Realize the research and development of fluid torque converter (hydraulic couplers), not only need good CAMM/CAD/CAM/CAE hardware and software platform, also need high performance liquid software for calculation in the link that designs.
The key point that realizes fluid torque converter (hydraulic couplers) research and development based on reverse-engineering is: from the original product to the three-dimensional digital model or two-dimentional drawing, from three-dimensional digital model or two-dimentional drawing again to the distorted signals of these two processes of trial product; Particularly for fluid torque converter performance (hydraulic couplers) material each impeller blade being arranged, spatially is three-dimensional curved surface, occurs bigger distortion in two above-mentioned processes especially easily.This distortion will cause the performance difference of trial product and original product.
At this distortion that is difficult to avoid, have following method to be solved usually:
1, improves the degree of accuracy of the precision of three-dimensional digital model.For example adopt high-precision measuring equipment; In the process of measuring, fully take into account the influence of undesired signal, when the preliminary treatment of three-dimensional digital model, remove these noises; Carry out fairing processing etc. to measuring the information of coming.
2, in the degree of accuracy of the existing suitable precision of three-dimensional digital model and product performance still through being difficult under the situation of meeting the requirements of, the three-dimensional digital model of setting up is carried out the Performance Calculation analysis, and some structural parameter to the three-dimensional digital model of original product correspondence on the basis of computational analysis are made reasonable modification.
Above-mentioned two kinds of methods have suitable difficulty in the specific implementation process.The identification of noise signal when the difficult point of first method is to measure, removal and to the realization of metrical infromation method for fairing; How as small as possible the difficult point of second method is the degree of accuracy of fluid torque converter (hydraulic couplers) Performance Calculation and variable parameter.
Summary of the invention
The design method that the purpose of this invention is to provide a kind of fluid torque converter.
The step of the design method of fluid torque converter is:
1) on advanced person's CAD hardware and software platform, sets up the digital mockup of car fluid torque converter, three-dimensional digital model is directly outputed to numerically controlled processing equipment with three-dimensional information, or the form of two-dimentional drawing offers manufacturing enterprise, after carrying out technology, frock analysis, carry out the first round trial-production of product;
2) experimental performance of the numerical property of first round trial product, original product is analyzed contrast, three-dimensional digital model to first round trial product improves design, and the 3-dimensional digital of the first round trial product after the improvement carries out second according to step 1) and takes turns trial-production;
3) with second, first round trial product, the calculated performance and the experimental performance of original product are analyzed contrast, improve three-dimensional digital model according to analysis result, and verification, improvement are carried out in all designs, finish the early-stage preparations of the batch process of product.
The present invention is different from general imitation design method fully.After sample is surveyed and drawn, at first data are analyzed fairing processing, reject from the original product to the three-dimensional digital model or two-dimentional drawing, from three-dimensional digital model or two-dimentional drawing again to the distorted signals of these two processes of trial product; Particularly for fluid torque converter performance (hydraulic couplers) material each impeller blade being arranged, spatially is three-dimensional curved surface, occurs bigger distortion in two above-mentioned processes especially easily.After finishing from the original product to the three-dimensional digital model, promptly adopt advanced CFD (computation fluid dynamics) analysis software that model is carried out computational analysis, and it is perfect to it is calculated that the result carries out structural modification to model, use CFD (computation fluid dynamics) analysis software to calculate again, until reaching our the set goal, and the method that does not adopt trial-production to test, a large amount of time and funds have been saved, and software calculate can also obtain testing the result that can not obtain, can replace most of test to a great extent.
