一、前言力的识别是通过测量系统的反应来确定激励力的时间过程。对许多情形来说,要直接测量力几乎是不可能的,因此,能够提供间接手段来确定力的实验方法是非常有用的。若这种识别力的实验方法既成熟,又简单,那么它在结构问题上的应用将会与日俱增。这种应用的一个例子是结构设计中在结构与目标间需要相互作用力时,水与土介质渗透物的设计。力的识别在控制风荷载产生的高层建筑的运动、运载工具通过空间的运动、动力试验、大空间天线和海洋平台中也都有应用。
First, the recognition of the prominence is to determine the time course of the incentive force through the reaction of the measurement system. For many situations, it is almost impossible to measure the force directly. Therefore, an experimental method that can provide indirect means to determine the force is very useful. If this experimental method of identification is both mature and simple, its application to structural problems will increase. An example of this type of application is the design of water-in-soil medium permeate when structural forces require interaction between the structure and the target. The identification of forces has also been applied in the control of the movement of high-rise buildings resulting from wind loads, the movement of vehicles through space, power tests, large space antennas and offshore platforms.
