Design simulation of twisted cord–rubber structure using ProE/ANSYS

A three-dimensional model of a twisted cord embedded in rubber matrix was investigated to estimate the interface stresses. CAD model of the twisted cord geometry through blended feature was carried out using Pro/ENGINEER software. Twisted cord model representative of a typical cord was developed and analyzed for a realistic analysis of cords used in cord–rubber structure. Finite element analysis was performed on the models under axial, and combined axial and lateral loading using the ANSYS software. A circular cord with surrounding rubber model was also analyzed and the results obtained were validated with other studies that exist in the literature. The stresses and deformations obtained from the finite element analysis are shown for various cases illustrating the effects of twist, rubber modulus, and non-circular cord.
