Global active noise control of a one-dimensional acoustic duct using a feedback controller Open

Andrew J. Hull, Clark J. Radcliffe, Steve C. Southward · 2024

The active noise control of a one-dimensional hard-walled duct with a partially dissipative boundary condition is addressed. Previous techniques have attacked this problem by developing adaptive filters designed to cancel acoustic noise at…

A High-Frequency Model of a Rectilinear Beam with a T-Shaped Cross Section Open

Andrew J. Hull, Daniel Pérez, Donald L. Cox · 2019

This paper derives an analytical model of a straight beam with a T-shaped cross section for use in the high-frequency range, defined here as approximately 1 to 35 kHz. The web, the right part of the flange, and the left part of the flange …

A High-Frequency Model of a Circular Beam with a T-Shaped Cross Section Open

Andrew J. Hull, Daniel Pérez · 2019

This paper derives an analytical model of a circular beam with a T-shaped cross section for use in the high-frequency range, defined here as approximately 1 to 50 kHz. The T-shaped cross section is composed of an outer web and an inner fla…

A Comprehensive Analytical Dynamic Model of a T-Beam Open

Andrew J. Hull, Daniel Pérez, Donald L. Cox · 2019

This paper derives a comprehensive analytical dynamic model of a T-shaped beam that includes in-plane and outof-plane vibrations for mid-frequency range analysis, defined here as approximately 1 kHz to 10 kHz. The web, right part of the fl…

A Modal Solution for Finite Length Rods with Non-Uniform Area Open

Andrew J. Hull · 2018

This paper derives a modal solution to the displacement field of a finite length rod whose area varies with respect to its length. This new method facilitates a solution to any problem where the area and derivative of the area can be repre…

Response of a Cylindrical Shell with Finite Length Ring Stiffeners Open

Andrew J. Hull, Geoffrey Moss · 2016

This paper derives a spatial domain wave propagation solution of a cylindrical shell that contains periodically spaced ring stiffeners.Previous work in this area has modeled the stiffeners as having a very short or very long length.This pa…
