Cushioning Performance Of Biomimetic Cobweb Cushioning Silicone Pad Research

Bearing is an important part of an equipment,and its surface quality has an important impact on the running state of the equipment.With the development of the transportation industry,bearings in the process of transportation tend to fall due to the impact of workers’ irregular handling,resulting in surface damage.Buffer liner is a layer of buffer protection device located between the outer packaging container and the protected product,which can reduce the damage of the bearing due to the impact and vibration in the process of circulation,and reduce them to the bearing can withstand the range.So the performance of the buffer liner directly affects the quality of the whole packaging system.Based on the advantages and disadvantages of several bearing packing methods commonly used at home and abroad,this paper introduces the performance of spider web structure and its application in real life,and puts forward a new design method of bearing cushion cushion based on the cushioning characteristics of spider web structure and silicone material.According to the morphology of cobweb in nature,the structure of cushion cushion is determined.According to the relationship between cushion cushion structure and its parameters such as radial wire and filament,the mechanical model and objective optimization model are established,the structural parameters of cushion cushion are obtained,and the thickness of cushion cushion is designed by consulting relevant standards.In the finite element software,the spiderweb cushion,high precision bearing and rigid ground were used to simulate the falling path.The solution module of the software is used to simulate the falling process of the bearing at three heights,and the corresponding stress neograms and time-stress curves are obtained.Through the analysis of the data,the maximum stress and the basic damage of the bearing in the process of falling can be obtained.The spider web cushion mould is printed by 3D printing technology.In order to facilitate printing and subsequent demoulding work,the mould is divided into three parts:the mould base,Part 1 and Part 2,and then printed separately.After the printing is completed,the mold is post-processed to ensure the assembly accuracy.In order to verify the correctness of the theoretical analysis and simulation experiment,cushion material,casting was a spider web structure in the laboratory through the drop test machine,data collector and acceleration sensor devices,such as simulation transport process of different height of packing in the fall,the landing impact acceleration by collecting bearing,and compared with bearing of fragility,analyzing the cushion performance of the cushion structure of spider web.
