The accuracy of the vibro-acoustic coupled system model for the low frequency range depends on how accurately modal characteristics are represented at the input, output, and the structure-acoustic cou....
Ride quality is one of the most fundamental properties of a vehicle, therefore this subject is always noticed by automotive engineers. A lot of researches have been done for improving vehicle ride per....
New power train concepts in the automobile industry will decisively change the familiar car acoustics. Secondary acoustic noise sources will be unmasked and dominate the driver's sound experience. The....
The role of acoustic cavity modes in vehicle NVH (noise, vibration and harshness) development is well established in the automotive industry today. Prior knowledge of these modes can help prevent pote....
Vibration insulation rubber parts are used in automotive applications to meet noise, vibration, and harshness (NVH) requirements. Some of these parts are located in high heat areas in the engine bay o....
In contrast to functionality and reliability, which are more and more assumed to be a natural and necessary condition of any vehicle, the performance of Noise, Vibration and Harshness (NVH) now belong....
It is well known that mufflers attenuate the engine noise essentially through dissipative and reflective effects. There is however another alternative technique for noise attenuation that has not been....
In connecting an exhaust pipe system to the body of a vehicle, a compromise between a soft attachment for good noise, vibration and harshness (NVH) behavior and a rigid attachment for optimum exhaust ....
Cepstrum analysis method is an important part in the area of modern signal processing subject, which has a good application in noise source identification. The paper uses cepstrum method to analyze no....
Increasing interest is being paid to noise pollution of internal combustion engines and as a result, recent international standards imposed more severe limitations to acoustic emissions on engine manu....
In current automotive research, increasing attention is being paid to the design of mufflers due to the lower noise levels which have been established by the acoustic international standards. The trad....
This paper describes the design measures taken to develop the noise and vibration performance of a new rear suspension and a new drivetrain system for rear-wheel-drive vehicles. The new rear suspensio....
The second part of a detailed examination of multivariate correlation of several axle assembly and component parameters to the assembly NVH performance (vibration) measured at the end of the assembly ....
The first part of a detailed examination of multivariate correlation of several axle assembly and component parameters to the assembly NVH performance (vibration) measured at the end of the assembly p....
