The importance of passive vibration isolator is increasingly growing owing to its stability of performance and low cost. In the previous paper, the authors proposed a nonlinear passive isolator for vertical direction based on a post-buckled L-shaped beam, which consists of two thin plates, and the performance of the proposed isolator in its unstable post-buckled state was numerically and experimentally investigated. In this paper, we newly propose the isolator which consists of two L-shaped beams and isolation table. The proposed model is desired to suppress the second and higher resonance. The validity of proposed systems are numerically investigated.
