When brake the car noises and vibrations make us uncomfortable and unstable. And the more technology for the automobile are improved, the more it should consider the driver"s emotional sides.
This study conducted analysis of Mode Participation Factor(MPF) about frequency that might cause unstability through Complex Eigenvalue Analysis to reduce the low frequency Squeal noise which is one of brake noises. And interpreted sensitivity, frequency and mode of the parts that cause unstability using participation factor that came from the analysis of MPF.
Suggested a solution which can reduce low frequency Squeal noise using Structural Dynamics Modification(SDM) by mass loading that is based on the result of sensitivity analysis. Complex Eigenvalue Analysis used a general program called ABQUS and conducted sensitivity analysis using linking index to minimize the effct of other frequencies except targeted frequency. We confirmed mode coupling through mode participation analysis and identified the effect of reducing the low frequency Squeal that came from the result of SDM of parts that have higher level of participation to unstability.
