Abstract: Vibration control, an important part of the mechanic science, is keeping enhancing its significance as the technology moving forward recently years. To achieve better performance, lots of efforts had been done in plenty of different ways, the active control, new materials, and new structures etc. Every approach have proved itself in the final performance of the vibration isolation, however, brought in several new problems such as the high energy-consuming, manufacturing cost, reliability, robust and so on. So to tackle with these kind of problems, a review has been done to consider most of the exist mounts and compare them to look into the breaking point of the new approach. After the review, the main direction of the research had been confirmed which was mostly concentrated on the navel structure approach. This kind of approach mainly used the passive to solve the problem, which can be much more energy-saving, lower cost and more robust. Addition to that, the structure can be extended into many transformed application to achieve different using scenarios. By the inspiration of the bio-structure, several structure were confirmed to be designed and optimized. The modeling and simulations of different structure approach were also done in the following paper. To complete the task settled in the very beginning of this paper, several prototypes of the best performing model has been manufactured and tested to estimate the real ability of vibration isolation of the designed structure. Several optimization of the structure had also been done to improve the structure.
