Diesel Engine Noise Control 4 Hours | Web Seminar or On Demand Course I.D.# WB1041 or PD33104ON
Introduction to NVH Aspects of Hybrid and Electric Vehicles 1 Day | Classroom Seminar I.D.# C1128 The influx of different hybrid and electric vehicle configurations has brought about unique NVH challenges from a variety of sources. NVH refinement is an important aspect of powertrain development and the vehicle integration process. While developing the NVH behavior of the vehicle is critical to satisfy customer expectations, it is also important to consider the influence of reduced exterior noise levels on pedestrian safety. This seminar introduces participants to basic NVH principles and unique NVH challenges encountered in the development of HEV, ReEV, and EV including engine start/stop behavior, electric motor whine, driveline NVH, body structure, influence of noise from accessories, and sound quality development, as well as potential countermeasures.
This web seminar provides an in-depth overview of diesel engine noise including combustion and mechanical noise sources. In ad- dition, the instructor will discuss a system approach to automotive integration including combining sub-systems and components to achieve overall vehicle noise and vibration goals. Learning Objectives By participating in this web seminar, you will be able to: • Identify and analyze commonly occurring diesel engine noise sources • Understand how analytical and experimental techniques can be used to solve diesel noise issues • Prescribe appropriate noise control analysis and solutions for specific diesel engine NVH issues Who Should Attend This course is ideal for those want to understand the root cause of many diesel engine noise issues, and how to use this understanding to better diagnose and control diesel engine-re- lated noises.
Learning Objectives Upon completion of this seminar, you will be able to: • Articulate the basic principles of NVH
