A Suggestion of Method to reduce the Radiation Efficiency of Dash Panel of a Passenger Car
- 발행 : 2002.11.01
초록
A study to determine the structure-borne noise radiated by a dash panel of a real car is performed by using the finite element method (FEM) and the boundary element method (BEM). The radiation efficiency is used to estimate the structure-borne noise radiated by a dash panel. The curved surfaces of a dash panel change the radiation efficiency. Experimental results of radiation efficiency of a simple rectangular plate and a dash panel show good agreements with the simulation results.
