Based On The Typical Structural Strength Of The Buckling Analysis

In this dissertation, the theories of finite element and the buckling analysis of shell are discoursed systematically. Under the direction of these theories, with the help of UG software and MSC/NASTRAN software, the defective casing texture is analyzed on static strength and buckling, And then, the maximum loads of the texture with different defect value are gotten, The changeable curve of the maximum load with the defect value and the permissible defect value are gotten. That the texture with various defects can be destroyed variously is discoursed in considerable detail as well. In addition, the structures of four track concrete paver and milling machine are analyzed on static strength and buckling by use of this software. The finite element analysis results can be of great use for verifying the security of loads and the economization of material. The results also present a proposal to design the structure reasonably. The research methods of the thesis and the results that the thesis provides have good consultant valuation for structure strength analysis.
