Hi, it is not dissimilar to that concept, however the angle over the rim is about 45 degrees, not 90. It is also complicated by the fact that the rope is in tension across opposite ends, and also the elastic properties of the Mylar material that is used to make these drumheads. Do you know if...
So I am not currently looking at the vibration in the skin, the purpose of the wave physics was to determine the surface tension at the boundary to produce X Hz f01 frequency in the centre. I have been trying to model the solution in abaqus with an experimentally determined downwards...
Hi, thanks for the reply,
@pinball1970 explained it well, the hoop itself is not fixed and will just sit on the head until the tension rods are inserted and are screwed down, applying the vertical force which pulls the hoop downwards with the drumhead, stretching the skin and applying the...
Hi, thanks for the reply,
I have a value for the surface tension at 587.15 N/m when the drum is tuned to a frequency of 123.47 Hz. To convert that to a stress tension uniform around the circumference of the membrane, is it acceptable then to just multiply it by the circumferential length of the...
I am currently designing an alternative to normal acoustic drum lugs and I need to find the forces that are felt by the tuning rods of a drum for the engineering background to my design. I have been able to use the 2D wave equation assuming uniform tension on the membrane and found values of the...
