Curved Surface Sliders
The Curved Surface Sliders or Pendulum isolators use gravity as the restoring force. Energy dissipation is provided by friction. The parameters of the bilinear constitutive law depend on the radius of curvature and friction coefficient. The can be designed and manufactured in two main types, with one (FIP series) or two (FIP-D series) primary spherical sliding surfaces that accommodate the horizontal displacement. Usually FIP-D series is preferred because of the smaller plan dimension.
