Andreas Hazir is investigating the door seal contribution to the interior noise level of production vehicles. These investigations contain experimental contribution analyses of real production vehicles and of academic test cases as well as the development of a simulation methodology for noise transmission through sealing systems and side windows. The simulations are realized by coupling transient computational aeroacoustics of the exterior flow to nonlinear finite element simulations of the structural transmission. By introducing a linear transmission model, the setup and computational costs of the seal noise transmission are significantly reduced, resulting in the feasibility of numerical contribution analyses of real production vehicles.

Über Autor(innen)

After studying technomathematics at the Technical University of Munich, Andreas Hazir started his tenure as a research assistant in the vehicle acoustics department at the University of Stuttgart. In 2014, he joined the aerospace application management team of a software vendor for computational aeroacoustics (CAA). His main field of work involves CAA simulations of aircraft, rotorcraft, engines and liners.
