The wave equation on a disk Bessel functions The vibrating circular membrane Recall: The shape of an ideal vibrating thin elastic membrane stretched over a circular frame of radius a can be modeled by u tt = c2∇2u, x2 +y2 < a2, u(x,y,t) = 0, x2 +y2 = a2. Last time, we saw that in polar coordinates this takes the form u tt = c2 u rr + 1 r u r ...

SIEBTECHNIK circular-motion screening machines are freely vibrating machines, that is, the vibration circle diameter adjusts itself freely in accordance with the mass ratio of screen box and unbalance mass. Circular-motion screens have a steep throw angle and therefore require a screen panel tilt of between 10° and 18°.

The number of vibrations or oscillations made in one second is called the frequency of vibration. The unit of frequency of vibration or oscillation of a vibrating object is hertz. When an object makes one vibration per second its frequency is said to be 1 hertz. If an object makes 10 vibrations per second, then its frequency will be 10 hertz.

The frequency of the (1,1) mode is 1.593 times the frequency of the (0,1) mode. When vibrating in the (1,1) mode a circular membrane acts much like a dipole source; instead of pushing air away from the membrane like the (0,1) mode does, in the (1,1) mode one half of the membrane pushes air up while the other half sucks air down resulting in air ...
