The work aims to propose a new type of cushion with bionic cobweb structure to solve the insufficient cushioning capacity of high precision bearing package cushion. According to the morphology of the flake cobweb in nature, the configuration of the buffer cushion of the cobweb structure was determined. According to the relationship between the structure of the cushion and the parameters such as the radial thread and the spiral thread, the mechanical model and the objective optimization model were established. The stress nephogram of the bearing and cobweb cushion under three drop heights in the finite element simulation environment was analyzed. The cobweb cushion mould was made and cast and the drop test of the bearing was completed. By analyzing and processing the data of the drop test, it can be obtained that the maximum stress of the bearing did not exceed the yield strength of the material. The impact acceleration of the bearing with cobweb cushion decreased by 86% and 78% respectively compared with that without the cobweb cushion at the drop height of 381 mm and 610 mm. It can be verified with the finite element simulation analysis. The research can provide technical support for the protection of high precision bearing in transportation drop.
