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.
