Extrusion damper configuration
Viscous dampers dissipate mechanical energy into heat through the action of viscous stresses in a fluid. The damper response to external stimulus (force or displacement) depends on the properties of the enclosed fluid. Non-Newtonian fluids have widely varying properties, enabling a range of possibilities for the damper response. We use numerical models to simulate the operation of dampers containing non-Newtonian fluids, such as viscoplastic fluids.
