FEA Simulation Based Thermo-mechanical Analysis of Tractor Exhaust Manifold

The main objective of this research work is thermo-mechanical analysis of tractor exhaust manifold. Present study analysed the response of exhaust manifold under higher temperature. Thermal effect was considered to evaluate the FEA simulation results. Free vibration based modal analysis was performed to find the fundamental frequencies. The solid model of exhaust manifold was designed using Pro-E. Finite element analysis was performed using Ansys 14.5. The parameter used for the FEA simulation is constant exhaust gas temperature of 800 °C which was applied to the exhaust manifold. The natural frequency and vibration mode of the exhaust manifold was obtained in modal analysis and vibration characteristics of exhaust manifold was analysed. The analysis show that the natural frequency of vibration varies from 53.2 to 466.68 Hz.
