Experimental and finite element analysis of mechanical behavior of nano-materials by improving elastomer structure used to dampen vibrations of crankshaft pulley

There is a growing interest in the automotive and defense industry, which is emerging in our country. The progress of the technology shows how important it is to use materials in engineering designs of the products used in these sectors. In this study, multi-walled carbon nano tube, nano-particle alumina and nano-particle zeolite were reinforced by using homogenous mixing, spraying and hand lay composite production methods for natural rubber and EPDM rubber. The obtained samples were subjected to rheological, thermal and mechanical tests. The mathematical model of the crankshaft was derived by using this study data, natural frequencies and mode shapes were found by modal analysis using the finite element method. A crankshaft is designed to absorb radial and torsional vibrations in the crankshaft. The information obtained from the experimental data of the strength of the crankshaft and the finite element method were used to derive the error rate. After finding the resonance natural frequencies of the crankshaft by means of FFT analysis, we have tried to verify it by modal analysis method using finite element program. The vibration damping six different pulleys were subjected to a motor simulation test and passed through acoustic controls. As a result of these studies, it was found that the crankshaft of the best homogeneous mixed carbon tube reinforced EPDM rubber is the best in terms of vibration damping.
