Abstract
Based on the absolute nodal coordinate method, the large deformation flexible multibody system with nonlinear constraints was investigated. The equations of motion were deducted by Augmented Lagrangian method. The primary unknowns in the equations of motion are independent of the constraint equations. Only taking the generalized positions as the primary unknowns, the elastic forces were evaluated by the invariant matrix method and the Broyden qusi-Newton method was introduced, which made the computation efficiency improved greatly. The simulation results for this kind of systems indicate the validation of the proposed method.
