Thermo Coupled Stress Analysis of Exhaust Manifold Assemblage using ABAQUS

Comprehension of the basic conduct in the beginning period of outline can help to lessen the quantity of virtual models and the time taken for their assessment. For an engine development program, the engine exhaust manifold system is a mind boggling framework subjected to thermo mechanical burdens. The investigation of such a framework is discriminating because of the many-sided quality of meeting the basic and stream prerequisites. In this paper the Thermal Stress Index (TSI) is created for down to earth reason. Especially the TSI is appeared to be extremely powerful in discovering an ideal shape with imperatives in outline of the exhaust manifold system. Therefore, the objective for discovering an ideal state of the exhaust manifold system is to minimize the TSI, and philosophy received to address a failure of an Exhaust complex amid physical testing on an engine test bed. A non-linear thermo-auxiliary quality investigation of the exhaust manifold system gathering of the four cylinder four stroke engine is done. The FE model comprises of the exhaust manifold system get together, head and mounting bolts. The contact interaction between the parts is likewise modeled. The assembly is subjected to bolt preloads, for reproducing the mechanical assembly. The thermal loads utilized as a part of the reenactment are computed through CFD (Input). The model considers a temperature reliance of a heat exchange coefficient on wall temperature in cooling sections. For the structural analysis temperature subordinate non-linear material properties and contact non-linearity is considered
