Abstract

This investigation focused on the adhesion between rubber pins and concrete slats by creating a rubber material and testing the adhesion between natural rubber pins and concrete slats. The pin features 15 distinct contact areas and densities. The adhesion of the rubber pin to the slat was then evaluated using both pulling and pressing force. The size of the contact area and the thickness of the rubber pins were found to result in a strong bond between the rubber pins and the slat concrete. The finite element method was used to calculate the reaction force between different types of rubber pins and concrete slats. When calculating the theoretical holding force, it was found that the theoretical holding force tended to correspond with the experimental results. Consequently, the cohesive force between the rubber pin and the concrete slat is a result of the reaction force. The force increases when the contact area, thickness, and mechanical properties of the rubber pin material are enhanced. This study determines the reaction force between the rubber pin and the concrete slat using the finite element method, which can be utilized to predict the adhesion between rubber fasteners and concrete slats in order to design animal pen slabs.
