非线性颤振 meaning in English

nonlinear flutter

At first , the finite element formulation is presented to determine the flutter characteristics of laminated panels at elevated temperature . then both the linear and nonlinear panel flutter characteristics are analyzed . the panel flutter boundaries are finally determined and the effect of temperature , airflow speed , etc , on the panel flutter characteristics is analyzed
为此，本文首先建立了复合材料壁板热颤振的有限元模型并对受热壁板的线性和非线性颤振特性进行了研究；最后确定了壁板的颤振边界，分析了温度、来流速度等因素对壁板颤振特性的影响规律。
