Abstract
A tunable hydraulic vibration damping mount comprises a universal outer housing, inner sleeve, main spring assembly, bottom compliance assembly, and inner bushing. Each of a plurality of flow channel members comprises a cylinder having a common inner diameter, a common outer diameter, and a helical track having a cross-sectional area and a length defining a volume of the helical track. The helical track of each flow channel member defines a different volume. A selected flow channel member is positioned between the inner bushing and the outer housing and between the main spring assembly and the bottom compliance assembly. The selected flow channel member provides a selected dynamic performance of the damping mount.
Claims25
A tunable hydraulic vibration damping mount comprising:
- a universal outer housing,
- a universal inner sleeve,
- a universal main spring assembly positioned at an upper end of said outer housing for pumping fluid through said mount,
- a universal bottom compliance assembly positioned at a lower end of said outer housing for allowing expansion during fluid flow when said main spring assembly is compressed,
- a universal inner bushing extending radially outwardly from said inner sleeve, and
- a plurality of fluid flow channel members, each of said plurality of flow channel members comprising a cylinder having a common inner diameter, a common outer diameter, and a helical track formed therein having a cross-sectional area and a length defining a volume of said helical track, each said helical track of each of said plurality of flow channel members defining a different said volume,
- a selected one of said plurality of flow channel members positioned between said inner bushing and said outer housing and between said main spring assembly and said bottom compliance assembly, said selected flow channel member providing a selected dynamic performance of said damping mount.
A method of tuning a hydraulic vibration damping mount comprising:
- providing a universal outer housing,
- providing a universal inner sleeve,
