Compliant mechanism is the focus of active research because of the stability, robustness, and ease of manufacturing endowed by their unitized construction. In this article, we explore an application of compliant mechanism for vibration isolation system with rigid foundation. Structural optimization approach is focused on the determination of the topology, shape, and size of the mechanism. The building blocks are used to optimize a structure for force transmission. The force transmitted to the rigid foundation through the isolator is reduced to avoid transmission of vibration to other machines. The design drawing model is compared with the existing isolator model, displacement transmissibility or amplitude for varying disturbance frequency and the force transmitted for corresponding disturbance frequency. Isolation efficiency of design drawing model is proven to be high when compared with the existing model.
