Abstract

Abstract

In order to deal with the eccentric connection problems of plate and beam reasonably in the structural analysis of vehicle, the constraint equations to the correlative nodes of plate and beam were involved in their balance equations, based on the theories of penalty element method and Lagrange multiplier method, which can solve the contribution problem of the eccentric connection to unitary stiffness matrix.A finite element program was worked out to solve the static intensity calculation problem of composite structure.Numerical computation result shows that the results of the two methods are both close to those obtained by finite element software ANSYS 9.0, the maximum errors of displacement and stress are respectively less than 1% and 2%, it indicates that the two methods are effective on dealing with the composite structure of plate and beam.
