Effect of the Curved Automotive Panels for NVH Performance Improvement

NVH 성능향상을 위한 복곡 자동차 패널의 효과

  • Published : 2009.07.01

Abstract

In order to enhance the dynamic stiffness of automotive panel, effect of bead and curved surface was investigated. Modal test was performed for principle specimens which have various kinds of beads, holes and curved surfaces. Test was also performed for conventional dash panel assembly and rear floor panel assembly and curved shaped ones. Results showed that curved shape increased the natural frequency of automotive panel more effectively than the bead. Finite element analysis was also performed and yielded good match with the test results.
