Resonance of flexural waves in gun tubes
WebA sine wave generator drives an open speaker to create a standing sound wave in a resonance tube. The driving frequency and the length of the tube are varied to study their relationship to wavelength and the speed of the sound wave. The concepts of nodes, anti-nodes, and harmonics are investigated for both closed and open tubes.

WebVibro-acoustic modulated responses are measured using laser vibrometry. The methods used for impact damage detection clearly reveal de-bonding in the composite panel. The high-frequency weak ultrasonic wave is also modulated by the low-frequency strong vibration wave when nonlinear acoustics is used for damage detection. Webcyclotron resonance. An average output power could be increased by operating the gyrotron continuously rather than in pulses. Using the second cyclotron harmonic allows the magnetic field requirement for resonance condition to be reduced by a factor of two, so that in 670 GHz gyrotrons the pulsed solenoid can be replaced with a cryo-magnet.
WebThe links below contain animations illustrating acoustics and vibration, waves and oscillation concepts. I started using Mathematica to create animations to help me understand and visualize certain acoustics and vibration phenomena in 1992 while I was a Ph.D. student in the Graduate Program in Acoustics at Penn State. For the next 16 years … WebIf we examine the standing wave patterns in figure 10, we can see that the first four standing waves represent waves with 1/4, 3/4, 5/4, and 7/4 cycles within the length of the tube. For a tube of length L this means that the first four resonance wavelengths are 4L/1, 4L/3, 4L/5, and 4L/7. If we know the speed of sound, we can calculate the ...
Web1. The formula you derive for the resonance frequency of an organ pipe won't have a radius variable in the formula. The resonance frequency depends only on the length of the organ pipe. Theoretically, it is correct. For practical purposes, this is strictly not true. The frequency measured always tends to be lower than what you theoretically ...
WebNote that the resonant frequencies depend on the speed of sound v and on the length of the tube L. Another type of tube is one that is open at both ends (known as an open-pipe resonator). Examples are some organ pipes, flutes, and oboes. The air columns in tubes open at both ends have maximum air displacements at both ends.
