The effective use of neural networks for fault detection, location, and classification requires training data. Distinguishing features in the data can be enhanced by pre-processing. Feature vectors that often prove advantageous in training networks for fault detection are modeshapes and curvatures; however, the procedures and sensors used to determine these can introduce problems. This paper uses numerical and practical experiments to investigate the use of acceleration, displacement, and strain response signals to extract modeshape and curvature functions from a cantilever plate and beam with localized damage. The importance of spatial accuracy, noise, and fault severity for fault detection is studied. It is shown that limiting spatial conditions occur with direct dynamic displacement measurements that have to be differentiated to obtain curvatures that can be overcome by using strain gauges that directly return quantities proportional to the curvature.

Passive Damping Conference

Passive tuned vibration absorbers (TVA) are widely used in reducing vibrations in machinery, buildings and many other vibrating structures. Recently, TVAs have been installed on structures for the purpose of reducing the sound radiation from the structure. As in the case of vibration control, the tuning and placement of TVAs for noise control is often based on the forced response of the structure, as opposed to the behavior of structural-acoustic interaction. This conventional approach for TVA placement on structures is not always effective for controlling sound radiation from the structure. This task requires proper control of the structural waves that couple well with the acoustic environment. This paper presents a preliminary study of acoustic radiation and radiation efficiency of panels instrumented with passive TVAs.

A fiber-optic Michelson interferometer is employed for sensing the vibration of a cantilevered beam. A small section of the sensing fiber arm is attached to the beam to sense the vibration of the beam. The active homodyne technique is used to obtain an electrical output which is proportional to the vibrational signal of the beam. A closed-loop control system comprises a pair of sensors and actuators, which are mounted nearly at the same point of the vibrating body, and an inverting power amplifier. The fiber sensor and a piezoelectric actuator are co- located on the root of the cantilevered beam. The fiber sensed signal is amplified and inverted, then fed into a piezoelectric actuator for exerting a dynamic control force on the body. Experimental results show that vibration of the beam is substantially reduced by applying a single control system with the fiber-optic Michelson interferometric vibration sensor.

The key to reducing processing costs, improving product yield, and optimizing material properties in composite materials fabrication is the use of intelligent process control (IPC). IPC completes the processing feedback loop by obtaining in situ sensor information, analyzing this information to make processing decisions, and then applying control parameters to the process in real-time. Information for IPC sensors must go beyond the traditional measurements of temperature and pressure, and include data such as resin viscocity, resin position within the mold, resin gelation-point, degree-of-cure of the composite, types of polymerization reactions taking place, presence of moisture, and the like. Two light-based sensors are described which have been utilized to obtain this information: (1) a novel infrared (IR) fiber-optic sensor, developed at BIRL, and (2) a commercially available index of refraction sensor. The information provided by these sensors relates directly to material performance. This paper also describes how neural networks were used to interpret the data collected by the IR fiber-optic sensor.

This paper is concerned with the dynamic response of truss structures containing linear- friction dampers. This type of passive energy dissipator shows different stiffness in loading and unloading, leading to triangular hysteresis loops under cyclic loading. The free and forced vibration responses of simple truss structures incorporating linear-friction dampers are analyzed. The harmonic linearization technique is used in combination with the modal strain energy method to estimate the response of truss structures with linear-friction dampers. The accuracy of this linearization technique is assessed in the context of truss structures in this paper. It is demonstrated that excellent accuracy is achieved using this linearization method.

This paper applies intelligent constrained layer (ICL) damping treatments to control bending vibration of composite plate structures. The ICL damping treatment consists of a viscoelastic shear layer sandwiched between a piezoelectric constraining cover sheet and the structure to be dampened. According to measured vibration response of the structure, a feedback controller regulates in-plane deformation of the piezoelectric layer to perform active vibration control. In this paper, the equation of motion and boundary conditions governing the bending vibration of a composite plate possessing bending-stretching coupling stiffness with ICL damping treatments are derived. Finally, a numerical example is illustrated on an infinite composite plate consisting of a (45 degree(s)/-45 degree(s)) angle-ply laminate subjected to plane harmonic wave excitations. Compared with existing passive constrained layer treatments, numerical results show that the ICl damping treatment can produce significant damping. In addition, there are certain orientations, determined by the structures of the composite laminate, along which the vibration amplitude can be reduced to a minimum.

A smart structural health monitoring system (SHMS) requires various sensing technologies to detect and locate flaws, and assess their criticality to the structural integrity of the aircraft. To realize its full potential, a SHMS must be capable of remotely sensing flaw growth and location. Acoustic emission (AE) is one of the few sensing technologies that is capable of direct and remote sensing of flaw growth. Currently, there are two AE sensing techniques used for monitoring, detecting and locating flaw growth in structural components. In one technique, specific AE event parameters are captured by narrowband transducers and are studied to identify their source and location. The other technique studies the whole AE waves captured by wideband transducers and then detects and locates flaw growth based on waveform analysis and the wave propagation characteristics of the structure being monitored. This paper investigates both AE techniques, establishes their limitations, and defines the goals that need to be achieved in AE technology before it can successfully be implemented into a SHMS.

An adaptation of an extrinsic Fabry-Perot interferometer (EFPI) strain sensor is described that permits the state of cure of an epoxy matrix to be monitored when the sensor is embedded in a polymeric matrix composite. By using a glass rod with a retroreflecting end for the target fiber in the EFPI sensor, the intensity of the light reflected depends on the refractive index of the host matrix, if a low coherence source is used. As the epoxy cross-links during cure, the refractive index of the epoxy will increase to a value exceeding that of the target fiber. The resulting increased loss in the fiber can be detected at the sensor output and correlated to the state of cure of the epoxy. After cure, the sensor may be operated as a conventional EFPI strain sensor if a coherent source is used.

The electromechanical surface damping (EMSD) technique, for controlling the peak vibration amplitudes of beam-like structures, is modified to extend the effective range of the approach. The technique is a combination of the constrained layer damping and the shunted piezoelectric methods, where the viscoelastic constrained layer attached to the vibrating surface is constrained by a shunted piezoelectric ceramic element. The mathematical model of the modified EMSD element is presented, implemented into a finite element algorithm and applied to demonstrate the ability of the technique to simultaneously and effectively suppress the first three resonant peaks of a generic aluminum cantilever beam.

This paper describes initial results of a fiber optic-based sensor during on-site testing performed by FEORC and Fiber and Sensor Technologies at Ingersol-Rand. Advantages of the fiber optic sensor are a demonstrated enhanced survivability, higher sensitivity, smaller size, electromagnetic interference immunity, and reduced risk of explosion. The conventional wire strain gages typically survive only a few minutes attached to the drill steel and drive chain, while the fiber sensors described here have survived over 400 hours and are currently still functioning properly. The tests described include the demonstration of strain energy measurements on the drive chain and drill steel, and displacement measurements of the piston within the drifter. All of the sensors tested can be used as both a laboratory evaluation and testing tools, as well as being an integral part of a proposed control and health monitoring system.
