Notes:
Structural analysis of automotive engine cover under vibration excitation is performed byfinite element analysis (FEA) in order to identify the critical area of the structure. Assembly load dueto the tightening of the bolts as well as the vibration excitation were considered to describe the actualloading condition. Natural frequencies of the system were extracted considering the damping effect ofthe structure. Dynamic analysis was performed based on the extracted natural frequency of the system.Experimental modal analysis (EMA) and measurement of strains were performed to verify the resultsof the analysis. Analysis results correlated closely with the experimental results. Analysis andexperiments showed that contribution of the assembly load should not be ignored to predict thestructural failure of the engine cover
