This paper is concerned with distributed sensors to measure the response of beam structures. The design of modal sensors for beam structures is well established. Most applications consider vibration control, but this paper is concerned with structural health monitoring, where the sensor output is made sensitive to changes in key stiffness parameters, for example in joints. The procedure is based on finite element models of beams, and thus the distributed transducers may be designed for arbitrary beam structures. A simulated beam excited by a rotating machine is used to demonstrate the approach and a Monte Carlo method is used to highlight the performance of the sensor in identifying damage.
