NVH - Background, Practice and Simulation Methodology

Description

In order to ensure the long-term success of a brand in the automotive sector, it is mandatory today to have a targeted design of the vibration and acoustic behavior of its products and thus achieve a high "perceived quality" of the company ' s vehicles. This functional design objective is generally called "NVH Noise, Vibration & Harshness". After vibration comfort has been one of the core objectives of vehicle development for a long time, the acoustics in the passenger compartment more recently also became a competitive criterion, which today receives a lot of attention in the automotive industry. The tasks of the NVH design can be divided into 3 areas: 1. Elimination of annoying vibrations. 2. Elimination of noise. 3. Design of the vehicle character. To meet these design objectives, extensive developments in the fields of measurement technology and simulation methodology have been undertaken in recent years.

Who should attend?

Newcomers and development engineers who wish to gain an overview of the topic. Designers and engineers who want to broaden their knowledge about NVH criteria in the vehicle development process. Simulation engineers from engineering service suppliers that are looking to enter the NVH simulation or want to optimize their services. Project managers and senior executives from vehicle and component development who want to gain a better understanding of the background of the NVH methods.

Course Objectives

In the two-day seminar, first the basics of NVH are presented. In this emphasis is placed on the physical background to understand the complex relationships in this field. Furthermore, the possibilities and limitations of simulation in the NVH area are explained using practical examples.

Prof. Dr.-Ing. Dietmar Jennewein
Darmstadt University of Applied Sciences

Prof. Dr.-Ing. Dietmar Jennewein studied mechanical engineering at the University of Kaiserslautern. He received his PhD in 1998 in the field of vibration technology. He then joined the Adam Opel AG in the "Vehicle Simulation" department and worked in the NVH group on the analysis of vehicle vibration and vehicle acoustics using the FEM. Since 2001, Mr. Jennewein was responsible as a group leader for all NVH simulation activity at Opel. He also led a multidisciplinary team for the metrological validation of the calculation procedure. Since 2011 he has been a professor at the University of Applied Sciences Darmstadt and lectures in the subjects of engineering mechanics, control and automotive engineering.

Prof. Dr.-Ing. Alexander Zopp
RheinMain University of Applied Sciences

Prof. Dr.-Ing. Alexander Zopp studied mechanical engineering at the Technical University of Darmstadt. He received his PhD in 2000 in the field of finite elements in acoustics. He then joined Adam Opel AG to work in the Vehicle Simulation Department. In the NVH group he analyzed vehicle vibration and vehicle acoustics with the FEM. Later, Mr. Zopp introduced the Statistical Energy Analysis (SEA) in the development process of Opel to expand the detectable frequency range in the simulation. He was responsible for the global simulation methodology in the high frequency range in the GM group. Since 2011, Mr. Zopp served as Group Head of NVH simulation at Opel. Since 2013 he has been a professor at the RheinMain University of Applied Sciences and lectures in the subjects finite elements, engineering mechanics, machine dynamics and NVH.
