Automotive Noise, Vibration & Harshness (NVH)
About the Program
This certificate program provides fundamental principles of acoustics and vibration theories, with emphasis on the applications of these principles to practical vehicle NVH problems. It covers basics of vehicle dynamics, free and forced vibration systems, acoustic wave propagations and transmission, acoustic interior trim and floor covering designs and analysis including Statistical Energy Analysis (SEA) technology, plus sound quality issues and vehicle audio system designs. (12 credit hours)
The certificate can be completed entirely on campus, entirely online, or through a combination of on-campus and online courses.
Course Descriptions
Please choose four courses to complete the required 12 credit hours.
A study of the linear vibrations of discrete multi-degree-of-freedom systems, generation of equations of motion using the unit displacement, unit force, and Lagrange methods are discussed. Generalized eigenvalue problem, modal analysis, effects of damping, synthesis of forced response by the unit step, unit impulse, Fourier series methods, response to shock excitation, and numerical techniques are also covered. (3 credits)
A treatment of the response, ride, and maneuvering of motor vehicles, road loads, suspension systems, and mechanics of pneumatic tires are discussed. (3 credits)
This course covers the fundamentals of acoustical waves, sound propagation and intensity, instruments for vibration and noise, HVAC system noise, automobile and aircraft noise, noise control techniques. Graduate standing or special permission required. (3 credits)
This course will examine the simulation of vehicle performance; dynamics in gear shifting; engine balance, fuel economy, and performance related to powertrains; powertrain arrangements, manual and automatic transmissions, automotive axles, four-wheel-drive systems; design and manufacturing of gearing systems. (3 credits)
Topics in kinematics and dynamics including engine output and balance; mechanisms and machine theory are covered. Force analysis and design of gears and shaft systems, analysis of planetary gear trains, and designs and analysis of automotive gear boxes are explored. (3 credits)
This course provides a system approach to the design of automotive chassis and body components and examines the influence of their design on the overall structural performance of the automobile. Design issues related to structural rigidity, ride comfort, safety and crashworthiness, durability and assembly are covered. Applications of advanced materials and joining techniques are discussed. Analytical tools used in automotive structural design are also discussed. (3 credits)
