Sound Radiation Analysis of Automobile Engine Covers
ثبت نشده
چکیده
A methodology to study the sound radiation of engine valve covers is presented. The analysis process uses a nonlinear static simulation followed by a steady state dynamics simulation to determine the sound pressure field due to the vibration of the engine cover. The effects of assembly loads are included. The methodology is demonstrated with two representative engine valve covers using acoustic finite and/or infinite element methods. Good correlation between the analysis results and available experimental data is achieved.
