Abstract
Various contact phenomena commonly occur during the deployment and operation of parachute systems that can significantly impact performance of the system. The development of experimental methods to evaluate dynamic contact in parachutes is extremely challenging. Consequentially, the study of contact phenomena in parachute systems has been extremely limited. Large-scale computer simulations of parachute systems provide an alternate method to study dynamic contact problems. In this paper, a parallel Computational Structural Dynamics (CSD) model based on a geometrically nonlinear, transient, finite element formulation is described for simulation of dynamic contact events in parachutes systems. Results from several preliminary simulations are presented to demonstrate the applicability of the CSD model for parachute systems.
