State and explain the working principle of hydrodynamic spring with neat sketch.
by

1 Answer

Answer :

Working principle: Hydrodynamic springs are comparatively small, thick walled cylinder in which the spring effect is produced by applying load to the fluid in the cylinder through a small piston entering at the centre of one end of the cylinder. The piston movement and deflection is produced by the compression of the fluid and deformation of the cylinder wall. These springs are particularly useful in applications requiring high load capacities and stiffness.
