Automotive NVH Analysis and Control 2 Day | Classroom Seminar (Available in China Only) I.D.# C1632 The course introduces the basic knowledge of vehicle noise and vibration, provides the analysis and control methods for noise and vibration sources, and transfer paths, and describes the occupants’ responses and control. The course is specially designed for NVH engineer and related graduate students. The course combines the NVH theory and engineering practices. After finishing the course, the students will deeply understand the mechanism of NVH and promote their capacity to solve engineering problems.
Learning Objectives By attending this seminar, you will be able to:
• Understanding the NVH knowledge for vehicle development • Mastering the NVH knowledge for vehicle development and learning engineering experience • Mastering the analysis and control methods of “Source-Transfer Path-Occupant” needed for vehicle NVH development
Who Should Attend • Vehicle NVH engineers
• Vehicle product development engineers • Vehicle attribute integration engineers • Graduate students in sound and vibration • Engineering experience is not needed, but helpful, especially experience in NVH Bachelor degree in mechanical engineering or electrical engineering or related engineering disciplines. Engineering experience is not required, but helpful.
