Design and Simulation of Vehicle Vibration

课程介绍

The vibration characteristics of vehicles have a significant influence on driving performance and ride comfort. Therefore the design of the vehicle structure with regard to vibration targets is an integral part of the car body design process. Numerical simulation has become an indispensable tool within this process. The evaluation and optimization based on simulation results is only effective if the user has a profound knowledge about the underlying theories, the idealizations of reality associated with the simulation and the integration of simulation results in the product development process. In this one-day seminar the design and validation process of the vehicle structure?s vibrational properties within the product development process will be presented. In particular, information on the theory of mechanical vibrations, the practical modeling and on the commonly used FE solvers Abaqus and Nastran will be provided. This information will be illustrated using practical examples from car body development.

谁该参加?

Engineers who are new in functional design and simulation. Designers, test engineers and technicians who want to expand their knowledge regarding the full vehicle design process. Simulation services providers who want to increase their understanding of vehicle vibrations to optimize their contribution to the car body design process. Project managers and managers from the vehicle and component development, who want to gain a better understanding of simulation methods.

课程目标

To understand the relationships of functional requirements and their design and simulation within the product development process. To Increase the knowledge about mechanical vibration theory as a basis for correct modeling and application of finite element software in vibration analysis. To expand the knowledge regarding vibration phenomena in vehicles and targeted design using computational methods.

Dr.-Ing. Olaf Kolk
BMW Group

Dr.-Ing. Olaf Kolk studied Physical Engineering Science and Mechanical Engineering at the Technical University of Berlin and the University of Michigan in Ann Arbor, USA. His doctorate was in the area of vehicle dynamics of car body structures. In 1999, Dr. Kolk joined the research and innovation center of the BMW Group in Munich, to first work in body development. There he has been responsible for the functional design of the BMW Z4 roadster body with regard to vibrations, passive safety and durability. From 2010 to 2014, Dr. Kolk led the material data management for simulation, which is concerned with material data and material inputs for simulation. Furthermore his work dealt with the integration of sustainability, durability and fatigue issues within current BMW product lines. From 2014 to 2017, Dr. Kolk headed the functional design and integration of body structure for the large BMW product line. Since 2018 Dr. Kolk works as a concept engineer and heads technical design of body and trim during the concept phase for various BMW models an product lines.
