The paper presents design solutions for reduction of gasdynamic noise from the passenger car exhaust system end pipe mouth. Data on overall levels and waterfalls of noise pressure obtained by experiment are provided. The best exhaust system design has been defined based on the results of the general levels analysis.
The article presents the developed method of determining the attachment points of the mounts of the exhaust system to the vehicle body. The requirements for the construction of a finite element model of the exhaust system are presented, the finite element model of the exhaust system is created, the results of natural frequencies and vibration modes and the strain energy of the structure are shown.
