Abstract

Abstract

Based on the finite element technology,using the finite element software MSC.NASTRAN,thethree-dimensional model of a large wind tunnel nozzle is established and the dynamic characteristics were explored.The modal analysis and transient responses were analyzed to obtain the dynamic response and dynamic characteris-tics (natural frequency and vibration modal),and then the analysis results are compared and verified by wind tun-nel vibration frequency experiments.The results show that the nozzle modal frequency distribution and dynamiccharacteristics are better,avoiding the main wind tunnel vibration frequency.
