Transient Analysis of Structures with Distinct Nonlinearities
Abstract
A hybrid method based on standard nonlinear and linear numerical procedures was implemented for the complete simulation of structural response for vehicles taxing over an irregular surface. Time history integrations of the equations of motion were used to determine the nonlinear suspension forces on the basis of a small number of model coordinates. The time history results were used as inputs to a second stage linear analysis by which means the more detailed vehicle elastic response was computed. The current capabilities of the method were demonstrated by its application to a simple beam vehicle model and also by the transient simulation of a typical fighter aircraft, taxing over and irregular runway. The results were compared with test data and direct time history analysis. Numerical problems in the computer implementation of the hybrid method were examined and feasibilities for future modification and improvement of the solution procedure were indicated.
