Abstract:
The pacer summarizes the numerical simulation of crash for helicopters using nonlinear finite element technique.The structures considered include the pilot seat, shock absorber, floor and skate.The problem is considered as dynamic response of the structure subjected to specified initial velocity or impulse load,with large deformation and plasticity.Special elements are designed to model the absorber and seat trail.Impact effects with ground are represented by gap elements.
Key words: crash worthiness .finite element, nonlinenr
