Method for automatically converting data among kinetic analysis, three-dimensional modeling and finite-element analysis software
2009
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, and displaying 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 design accuracy and the design efficiency of products.
