The Impact of Temperature Effect on Exhaust Manifold Thermal Modal Analysis

The impact of temperature effect on exhaust manifold modal analysis is analyzed in this study. Firstly, the temperature field is mapped from the CFD software and then heat conduction process is analyzed in FEM software with the temperature field boundary conditions. At last the modal analysis that considers temperature effect is done. The frequency and vibration mode between cold modal and thermal modal’s are compared. The result shows that temperature has a great influence on the manifold mode and it is very valuable to product design.

Study on Influence of Temperature to Section Deformation of Steel Box Girder during Cantilever Installation

Because of solar radiation and the atmospheric temperature rise, the temperature change of the steel box girder bridge be larger. Thermal conductivity and sensitivity to the temperature change of steel is very good. The impact of temperature effect can be compared with the dead and live load under certain circumstances. Taking a bridge as example, the relative deformation of flat steel box-shaped girder is analyzed with the finite element analysis software. The results can be reference for other bridges.
