Smartphones and mobile devices have greatly penetrated the daily lives of many people. While participatory/pervasive sensing has gained wide adoptions by leveraging various onboard sensors on mobile devices, another powerful resource, the computational power on these mobile devices has been less frequently harnessed by researchers and practitioners. To fill this gap, we propose in this work the modeling,...
For the analysis of car interior noise at high speed, the influence of autobody aerodynamics should be taken into account, besides the vibration and acoustic radiation of powertrain, the random excitation from road and the vibration inputs of tires, and so on. A model of CFD was built. And the most turbulent area of autobody surfaces was located. The spectrum of average aerodynamic pressure of monitoring...
Application of statistical energy analysis (SEA) method on analysis and control of automotive interior noise from powertrain is introduced. An SEA model is presented for interior noise reduction. The SEA model is composed of a number of subsystems based on a 3D model with all the parameters for each subsystem. The inputs were measured through road tests in different measurable conditions, including...
