NVH (Noise, Vibration & Harshness) Analysis
NVH Analysis
NVH (Noise, Vibration & Harshness) Analysis is a specialized engineering discipline that focuses on understanding and reducing unwanted sound and vibration in mechanical systems. This course provides in-depth knowledge of the sources, propagation, and control of noise and vibration in vehicles, machines, and structural systems. It combines principles of mechanical dynamics, acoustics, signal processing, and computer-aided engineering (CAE) to prepare learners for real-world NVH testing and simulation.
🧠 What You Will Learn
The course begins with the fundamentals of noise and vibration theory, exploring concepts such as sound pressure levels, frequency response, damping, transmissibility, resonance, and modal analysis. It progresses to hands-on modules involving structural dynamics, acoustic modeling, and vibration isolation techniques.
💻 Tools & Techniques Covered
Learners will gain proficiency in both physical testing and simulation techniques. The course covers FFT analysis, frequency domain diagnostics, acoustic signal filtering, and modal testing. Software tools like LMS Test.Lab, Brüel & Kjær, ANSYS Workbench, HyperWorks, and NASTRAN will be used for simulating and analyzing NVH performance.
Training also includes working with accelerometers, microphones, impact hammers, and data acquisition systems. Learners will conduct real-time analysis and interpret graphs like waterfall plots, Campbell diagrams, and order tracking maps to resolve design flaws.
🏭 Industry Applications
NVH engineering is essential in designing quieter and more comfortable vehicles, aircraft, appliances, and industrial equipment. In the automotive sector, NVH analysis influences everything from engine design and suspension systems to cabin acoustics and road noise insulation. In aerospace, it ensures comfort and component stability under varying pressure and altitude conditions.
Consumer electronics and industrial machinery also rely on NVH techniques to enhance usability and reliability. This course equips learners to contribute to design refinement, quality testing, acoustic optimization, and regulatory compliance across industries.
🎯 Who Should Enroll?
This course is ideal for mechanical, automotive, aerospace, and acoustics engineers, as well as R&D professionals, CAE analysts, and testing engineers. It benefits those entering roles in vehicle design, quality assurance, product development, or systems integration. Professionals already familiar with basic vibration and structural dynamics will gain advanced insights into applying NVH practices effectively.
