Abstract: |
Silicone rubber is widely used as sealing material in many fields due to its excellent properties, and the sealing performance is closely related to contact characteristics. In this paper, both theoretical and experimental methods are used to study the contact characteristics between silicone rubber and smooth surface, focusing on revealing the variation of contact pressure and contact area during the compression process. The mathematical expressions of contact pressure and contact area are obtained based on Hertz theory, and then the compression test of silicone rubber is carried out used the rubber mechanical properties testing platform. The results show that the contact area and contact pressure increase with the increase of compression. Under the same compression, the elastic modulus of silicone rubber has little effect on the contact area, while contact pressure and elastic modulus are positively correlated. The theoretical results are in good agreement with the experimental conclusions, which provides reference for the seal design. |
