抄録

In this report, we investigate the basic properties of a nonlinear vibration isolator utilizing post buckled L-shaped beam structure. The isolator consists of two thin plate beams jointed perpendicularly. One beam is fixed vertically to the base and the other fixed horizontally. An isolating object is supported at the joint of two beams and if the mass of object is larger than buckling load of the beam frame, the beam buckles and the object is supported by post buckled beam. Since post buckled beam possess the property of high-stiffness-low-dynamic-stiffness, this system is efficient as a passive vibration isolator in vertical direction. This report shows the basic property of this isolator by the numerical analysis by FEM and the experimental results.
