描述了一种通过结构部件的振动模式来表示其结构部件的方法。用于描述部件的模式可以使与结构的其余部分的连接点自由或固定，或使某些点自由和某些点固定。这些模式既可以是计算的，也可以是实验测量的。可以使用静态确定的挠度影响系数来提高表示的精度。该方法所声称的优点源于计算(或测量)分量振型的条件的普遍性。因此，可以选择边界条件来优化精度，或者在已经获得模式的情况下，该方法允许使用可用的数据。文中给出了算例，说明了该方法的应用，以及从静态计算中得出的改进的意义。
A method is described for representing a structural component by means of its vibration modes. The modes used to describe the component may have the connection points to the remainder of the structure free, or fixed, or some points free and some points fixed. The modes may either be calculated or experimentally measured. Statically determined deflection influence coefficients may be used to improve the accuracy of the representation.The advantages claimed for the method derive from the generality of the conditions under which the component modes are calculated (or measured). Thus the boundary conditions may be selected to optimize accuracy or, in the event that the modes have already been obtained, the method permits theavailabledata to be used. Examples are presented that illustrate use of the method, and the significance of the improvements derived from static calculations.
