The described digital mockup of the embodiment of the invention (bank bridge) integrated development method and integrated development system can utilize shore container crane digital mockup expert design system platform; The design system data management platform.
The described digital mockup integrated development method of the embodiment of the invention and integrating and developing platform system can design data drive solid model, solid model data driven analysis model method.
The described digital mockup integrated development method of the embodiment of the invention and integrating and developing platform system can realize realizing data sharing between each platform, can carry out in real time the iterative modifications method, Parameterized Design System and method, and on-the-spot installing simulation system and method.
The present invention is based on and adopts Visual Studio+SQL Server+Pro/E+Ansys+Adams software, make up parameterized three-dimensional model and simulation analysis model, the basis of formation database, by the system integration, data sharing, realize the functions such as design analysis emulation of each system, carry out parametrization and drive design.
Other three-dimensional softwares are such as Inventor, UG-NX, CATIA etc., analysis software is such as Hyperworks, Patran/Nastran etc., simulation software as: RecurDyn, LMS.motion etc. also can be integrated by this technology, finish the digital mockup design system under the present invention.
Method and system described above can be equally applicable to a bridge, specifically no longer describes in detail.
The principal feature of the method for the invention and system:
1. adopt modular technology, make up the Parametric designing architectural framework towards product family, product design process is divided into theoretical method layer, system development layer and output layer as a result.On the basis of given basic model, by the Parameterized Design System of exploitation towards product family, set up product function model, principle model and structural model towards product family.And carry out Rapid Product configuration design for the particular customer demand on this basis, and coordinate the contradiction between personalization of product demand and the economical efficiency of scale, the target of producing to satisfy mass customization namely provides high-level efficiency, cheaply personalized product design.
2. adopt the digital mockup designing technique, saved the number of times of actual tests, reached the effect of energy-saving and emission-reduction.The designer can carry out assembling test in computing machine, running test, and performance test, calculated rigidity and intensity have improved designing quality, have reduced the physical test number of times, have reached the effect of energy-saving and emission-reduction.
3. adopt modularization, Parametric designing, improve enterprise's designed capacity.For these specialities of bank bridge, analyze its functional structure, formulate the principles such as suitable Module Division, coding, realize modularization, Parametric designing, thereby reduce the intensity of designer's repeated work, shorten the design cycle, improve the designed capacity of enterprise.
4. adopt Analysis of Structural Characteristics, improve the reliability of product.The method such as modal parameter verification analysis result is optimized its finite element model by experiment, carries out quiet, the dynamic analysis of finite element, guarantees the reliability of product in the design phase.
5. adopt light-weight design theoretical.Under the prerequisite that guarantees rigidity, intensity, reliability, according to bionics principle or topology optimization design, by changing section forms of beam or the arrangement form of structural member being adjusted, save material, reach the lightweight of structure.
Advantage of the present invention and good effect are: adopt the digital mockup technology, product is carried out modularization, seriation, standardization according to structure and configuration, set up various databases, template base, calculating storehouse, optimized design flow process and the method for combing, conclusion and summary product are set up one and are overlapped product design expert integrated system quick, optimum, standard.This system has parametrization and drives the advantages such as design, finite element analysis optimization, simulation analysis, virtual assembling.Thereby reduce R﹠D costs, shorten the R﹠D cycle, improve the quality of products.
The above only is the preferred implementation of the method for the invention and system; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
