摘要
Abstract
Based on the theory of rigid-flexible coupling dynamics, the dynamics simulation of flexible nozzle in wind tunnel is done by using the software of ADAMS and PATRAN/NASTRAN. At the same time, the nonlinear deformation of flexible wall is analyzed through the finite element software of NASTRAN. The comparison of these two results indicates that neglecting the nonlinear deformation of the flexible wall can bring big errors to the dynamics simulation. Therefore, the dynamics simulation model is improved by using the segmented linearization method and the nonlinear deformation of the flexible wall is reckoned in. The result shows that the improved dynamics simulation is accurate and is applicable for the control design of the flexible nozzle. Finally, the influence of the handspike drive on the structure strength of the flexible wall is analyzed which can provide essential basis for the control of the handspike drive and avoid the damage of the flexible wall.关键词
