In order to investigate the windblast protective devices’ effects on the aerodynamic characteristics of human-seat system, two geometric modes were built, one was installed protective devices, the other was not. Used the FLUENT, a CFD software, a series of simulation experiments were done. The two models’ contours of pressure and curves of aerodynamic force parameter were obtained. Besides the rule of how the protective devices effect on human-seat system was obtained. These results had some referenced worthiness for designing protective devices.
