![]() This paper provides a guideline for the design, analysis, and optimization of BVIs. BVIs should be carefully designed to avoid the interwall oscillation to ensure a considerable vibration isolation performance due to the effects of initial equilibrium position. ![]() The results demonstrate that BVIs can provide negative and softening stiffness characteristics to broaden the isolation band, and a shallower potential barrier and intrawell oscillation are beneficial to vibration isolation. A feasible model of BVIs is applied to quantitatively verify the advantages of BVIs in vibration isolation. The Vibro vibration control product range includes vibration isolators for vibration reduction for HVAC systems, fans, pumps, generator sets, elevators, cutting-machines and other equipment. The theoretical and numerical transmissibilities are calculated. Advanced vibration isolators are necessary in order to stop the transmission of vibration near the source. Vibration isolators and rubber buffers are available in different shapes and sizes. Vibration isolation is a commonly used technique for reducing or suppressing unwanted vibrations in structures and machines. The generalized force and displacement transmissibilities of BVIs are deduced. A wide range of anti vibration mounts, commonly known as vibration isolators, in natural rubber with steel base plates or in AISI 304 stainless steel to dampen unpleasant vibrations that can disrupt machine operation and create shocks or noise. Typical applications include air handling units, air conditioners, compressors, pumps, machine tools, motors, business machines, transformers, furnaces, etc. The nonlinear restoring force and potential energy are obtained through analyzing the general model of BVIs with “three-spring” quasi-zero stiffness (QZS) model. Vibration isolation mounts are used to help minimize or prevent noise and vibration from transferring between equipment and floor or solid support structure. This paper presents a general theory for bistable vibration isolators (BVIs) and reveals the bistable vibration isolation mechanism. Bistable structures have been widely used for vibrational energy harvesting, the corresponding potential vibration isolation application has also received attention recently.
