ABSTRACT:
A resilient support element for a compliant hydrodynamic fluid film bearing has top and bottom corrugated foil modules separated by a thin mid-plane sheet. Both modules are split by slits extending perpendicular to their corrugation axes, and the two modules are arranged with their corrugations extending transverse to each other. The angular stiffness of each finite area of the support element is substantially equal about orthogonal axes over its entire area. The support element provides superior damping and soft, strong isotropic support of the bearing sheet for generation of high load capacity at low speed, stable operation and high load capacity at high speed, and tolerance of manufacturing, use and loading abberations.
