Abstract
Briefly, according to this invention there is provided a viscous fluid mount for interconnection between a vibrating body and a base. The viscous fluid mount includes a chamber, a high viscosity damping fluid contained within the chamber and a flow resistance device. Input energy from the vibrating body is dissipated by shear friction of the damping fluid moving parallel to the shear surface area of the flow resistance device.
Claims17
A viscous fluid mount for interconnection between a vibrating body and a base, said viscous fluid mount comprising:
- a chamber defined by an elastomeric housing having opposing cover brackets, one of said cover brackets adapted to be connected to the vibrating body and another of said cover brackets adapted to be connected to the base;
- a high viscosity damping fluid contained within said chamber;
- and
- a flow resistance device positioned within said chamber and operatively connected to one of said cover brackets and having a shear stress surface area and a normal stress surface area, said shear stress surface area being greater than said normal stress surface area, such that input energy from the vibrating body is dissipated primarily by shear friction of said damping fluid moving parallel to said shear surface area;
- each said cover bracket including a circular base plate and a boss, said elastomeric housing having internal and external diameters, said base plate having a diameter greater than said housing external diameter, said boss having a diameter approximately equal to said housing internal diameter.
