Abstract

The invention discloses a method for automatically converting data among kinetic analysis, three-dimensional modeling and finite-element analysis software, which comprises the steps of: starting mechanical system kinetic analysis software, and loading a virtual prototype to carry out kinematics and dynamics simulation; generating a CMD command file recognized by the mechanical system kinetic analysis software in the three-dimensional modeling software by using relevant plug-ins; deriving a mode neutral file corresponding to a model in the finite-element analysis software; reading the generated CDM command file and the mode neutral file by using the mechanical system kinetic analysis software and carrying out rigid-flexible mixed simulation; circularly correcting and flexing the model, anddisplaying a better result on screen and storing data files. The method for automatically converting the data is applied to complex mechanical system design and analysis, which can improve the designaccuracy and the design efficiency of products.

Description

Technical field [0001] The invention relates to the field of mechanical design, in particular to a method for automatically converting data between dynamic analysis, three-dimensional modeling and finite element analysis software. Background technique [0002] At present, there are many engineering softwares such as CAD / CAE / CAM, which are applicable to different professional technical fields (such as modeling design, kinematics dynamic analysis, finite element flexible analysis); even if they belong to the same field (such as various high-end CAD modeling Software Pro / E, UG, CATIA, etc., various large-scale CAE analysis software ANSYS, ADAMS, MSC.NASTRAN, etc.), they also have their own characteristics and advantages, and make full use of these powerful engineering design software for joint design of complex mechanical systems And analysis can greatly improve product design quality and increase product design efficiency. Due to the relative independence of various software syste...
