This book is the first of its kind. It provides the reader with a logical and highly quantitative means of including noise as a parameter in the early design stages of a machine or structure. The unique and unified methodology builds upon the familia

Piezoelectric materials' excellent dynamic performance, high energy density, and incremental positioning capability have motivated their use for solid-state actuation. However, harnessing a piezoelectric material's low-displacement and high-force ele

The concept of customer preference, or product value, prevalent in economics and management science, is just beginning to be used in engineering design. This concept and the associated measurement approaches offer us a theoretically appealing way to

Multi-tuned vibration absorbers are attractive in reducing vibration and noise over a broadband. Here, an efficient and robust dynamic reanalysis algorithm is presented for predicting the dynamic response of a base structure to which are attached mul

Particle impact dampers (PIDs) are enclosures partially filled with particles of various sizes and materials. When attached to a vibrating structure, they add damping by dissipating energy through inelastic particle-enclosure collisions as well as th

A nonlinear motion transmission mechanism for improving the mechanical work output of an active material drive element is presented. This improvement is achieved by addressing the typical mismatch between the characteristics of a driven load, such as

A bimorph-driven rotary motor has been developed, and demonstrated in a flow-control actuation application. A rotary (roller) clutch rectifies bimorph-powered oscillation into rotational motion to convert electrical to mechanical power. Through a pro

An inertial actuator (also known as a proof mass actuator) applies forces to a structure by reacting them against an “external” mass. This approach to actuation may provide some practical benefits in the active control of vibration and structure-

When modelling the dynamic response of an existing structure to predict the effects of design modifications, many types of forces are difficult to characterize, e.g., those due to unsteady flows or acoustic excitation. To model the forcing function i

This paper describes a method for optimally designing a structure to “best fit” a specified set of acoustic characteristics, e.g., sound spectrum or radiated power. The method links the disciplines of structural dynamics, acoustics and optimizati
