Chen Dong-xing, Xiong Rui, Wu Jian, et al. Modal Analysis of the Exhaust Manifold Assembly Based on the ABAQUS[J]. 2013, 30(2): 103-106.DOI: 10.3969/j.issn.1007-7162.2013.02.020.
By establishing the finite element model for the automobile exhaust manifold assembly
it divided the model into many systems with freedom
used ABAQUS software to do a modal analysis
and obtained the exhaust manifold assembly of vibration frequency and natural vibration model. The analysis provides reference for designers to avoid resonance and it provides necessary conditions for fatigue analysis as well as response analysis.
