Damping Constant
Damping Constant
(OP)
Hi,
Can someone help me work out the damping constant of a cylindrical viscous damper. I know the viscosity of the oil, the ID of the tube, the OD of the piston and its velocity. The oil is effectivly being forces through an annular area from one side of the piston to the next.
Any help appreciated.

RE: Damping Constant
you can probably find how to calculate the force vs. velocity for the piston by looking in a fluids textbook.
using F = -cv, you can relate your coefficient c to the F and v that you calculate or measure.

Sorry didn't know the piston velocity initially but determined it by testing. Can c be calculated without knowing velocity at this stage?
