【摘要】 介绍建立管系结构固有频率和振型向量方程的基本理论,建立管道结构的动力有限元方程,用ANSYS程序对其分析,得出管系结构固有频率和振型,从而判断管系是否与其它系统产生共振,并为管系的动态设计和减振提供依据。更多还原

【Abstract】 This article introduced elementary theory of the pipeline structure natural frequency and mode shape vector equation.The dynamical finite element equation of the pipeline structure was established.Using ANSYS procedure,the pipeline structure natural frequency and mode shape were obtained,through which the judgement of the pipeline resonance is provided.更多还原
