Description
Technical field
The present invention relates to the structure analysis method for glass fiber reinforced materials, be specially one for glass fiber reinforced materials also
Structure analysis method based on abaqus and moldflow associative simulation.
Background technology
Currently, research fibre reinforced composites have become as the technical problem paid attention in the world, at military aspect: fly
Machine, rocket, artificial satellite, naval vessels, etc. military equipment all gradually form very composite manufacture；At civilian aspect: compound
Material played an important role in fields such as means of transport, building structure, Medical Instruments.Fibrous composite is according to structure
Appearance formula is divided into: single layer composite, laminated composite material, short fiber composite material.Short fiber composite material its mainly apply
Field is automobile industry, can be used for the manufacture of constitutional detail；Can be used for the manufacture of aircraft interior non-structural part；Fiber is composed
Giving the thermodynamic property that goods are good, short fiber composite material is also applied for manufacturing the device near thermal source.Additionally at electrically electricity
Son and home appliances aspect are also widely used.
Different composite material has different manufacture methods, and injection mo(u)lding is a kind of important processing side of short fiber composite material
Method.In injection molding process, fiber flows together along with matrix in mold cavity, makes chopped fiber produce in different positions
Different orientations, so that the material after molding and the diverse location in goods present different microstructures.In forming process
In, melt temperature, injection pressure, die profile and working process parameter all can produce impact to the end-state of fiber.
In addition, it is also possible to obtained the composite wood with diverse microcosmic structure and mechanical property by the selection of component material and coupling
Material.In order to by short glass fiber reinforcing material preferably be applied to life in, for short glass fiber reinforcing material mechanical property research just
Seem and become more and more important.Main approaches for short fiber reinforced goods is broadly divided into following three kinds of methods now: (1) short fibre
Dimension strengthens goods typically by injection mo(u)lding, and flow process and the generation result thereof of matrix in injection moulding process are carried out by Moldflow
Consider, so can be carried out each side such as filling, pressurize, cooling, warpage, fibre orientation in Moldflow more comprehensively
Analyze.(2) associating two kinds of softwares of Abaqus and Mlodflow carry out mold flow analysis and structural analysis.Because the structure of injection-molded item
Analysis can not rely on general injection CAE to carry out, in addition it is also necessary to other outstanding structure analysis softwares, Abaqus becomes industry already
The general outstanding finite element that the interior function generally acknowledged is the strongest, abaqus has directly and the interface of moldflow, it is possible to directly lead to
Cross two kinds of softwares of associating Abaqus and Mlodflow and carry out mold flow analysis and structural analysis, also become prediction and checking to chopped fiber
Strengthen the effective means of composite materials property.(3) associating tri-kinds of softwares of Abaqus, digimat and Mlodflow carry out mould
Flow point analysis and structural analysis.First application Moldflow obtains fiber distribution situation in the structure and directional information；Then should
The mapping of machine direction data is realized with Digimat；Finally application Abaqus carries out the finite element analysis of structure.But it is current
There are again some problems in three kinds of methods: for first method, is not the structure analysis software of specialty due to Moldflow, so
Some simple structural analyses can only be carried out for naive model by Moldflow, sometimes can not obtain research worker and want
Analysis result；For second method, associating two kinds of softwares of Abaqus and Mlodflow carry out mold flow analysis and structural analysis,
Although comparing first method, labyrinth can be carried out structural analysis, however should need in this way abaqus and
The coupling completely of moldflow software version, the so hardware requirement for user are the harshest, and this mapping method
Having strict requirements for analyzing the grid of model, motility is the highest；For the third method by third party software
Digimat, makes computational methods become complicated and expend more fund because introducing software of the third party, and this method is
The biphase supposition comprised according to material material constitutive out is mapped in structured grid, the mechanics of the material that actual process makes
Performance is not consistent with the result of prediction, the result of prediction is brought in structure and carries out structural analysis and be inaccurate.
Summary of the invention

Rate, as long as keeping consistent with geometric model during stream mode division analysis, research worker can be according to the demand utilization geometric model of oneself
Repartitioning grid, after having mapped machine direction, research worker can compose material properties according to test data, and research worker also may be used
With by writing subprogram tax material properties.In abaqus, complete model boundary condition apply, and field variable, time output
Job just can be submitted to after definition to calculate.This kind of method has been combined two kinds of softwares of abaqus and moldflow and has been carried out mould flow point
Analysis and structural analysis, can be suitable for complex model and complex working condition.Integrated processes before comparing, this kind of method is more flexible,
While it by third party software, can not be suitable for the grid of stream mode division analysis and the inconsistent situation of grid of structural analysis, also
Research worker requirement self-defining to material can be met.
