Modeling and Motion Analysis of Multi-bodies Dynamic of Unmaned Parafoil Vehicle

Abstract

Abstract: Unmanned Parafoil Vehicle (UPV) has gradually become a hotspot in the flexible wing vehicle research filed for its superior fight performance and advantages in application. An eight degrees of freedom (DOF) nonlinear dynamic model of UPV in mechanism law was proposed, aiming at the structure characteristics of the two flexible connections, and considering the added mass of canopy and the relative motion of two bodies. The response of model to different levels of thrust changes was simulated and analyzed, pulling a single steering line and pulling the left and right steering lines of canopy symmetrically on the steady state of gliding. The simulation results illustrate that operator will cause the relative motion between two bodies which cannot be ignored, and also verify the validity and utility of model.
