本文提出了一种同时满足固有频率、振型节线（点）位置要求的结构动力学设计方法。该方法先建立了振型节线（点）位置及变化与独立设计参数的关系，然后在某些约束下利用优化方法求解设计结果；文中同时还给出在模态空间中的固有频率、固有振型的灵敏度分析数值计算方法．算例表明它能有效地解决一些工程结构设计时涉及到固有频率、振型节线（点）位置要求的结构动力学设计问题。
This paper proposes a structural dynamics design method that simultaneously satisfies the requirements of the natural frequencies, vibration mode pitch (point) positions. This method first establishes the relationship between the position and variation of the vibration profile line (point) and the independent design parameters, and then uses the optimization method to solve the design results under certain constraints; the natural frequency in the modal space is also given Vibration mode sensitivity analysis numerical calculation method. The example shows that it can effectively solve the structural dynamics design problems involved in the design of the engineering structure, which involves the natural frequency, vibration mode pitch (point) position requirements.
