Overview
The NVH Learning Lab is designed as an integrated learning platform that combines theoretical instruction, numerical simulation using Abaqus (SIMULIA), and experimental validation. The objective is to provide students with an industry-oriented learning experience by enabling them to correlate computational predictions with physical measurements.
Students first learn the fundamentals of vibration, acoustics, structural dynamics, and Noise, Vibration and Harshness (NVH) through the elective course. They then develop finite element models in Abaqus, perform modal and dynamic analyses, and predict the vibration and noise behaviour of engineering components. Finally, these predictions are validated experimentally using the NVH Learning Lab through sensor-based measurements and data acquisition systems.
This integrated approach follows the standard engineering design cycle adopted in the automotive, aerospace, railway, and heavy engineering industries.
Role of Abaqus in the NVH Learning Lab
Abaqus serves as the primary simulation platform for validating the design and performance of the seven NVH experimental test rigs. Students will learn to:
- Develop finite element (FE) models of beams, plates, shafts, and other structural components.
- Perform modal analysis to determine natural frequencies and mode shapes.
- Conduct frequency response and harmonic analyses to study vibration behaviour under dynamic loading.
- Investigate the influence of material properties, stiffness, damping, and boundary conditions on NVH performance.
- Compare numerical predictions with experimental measurements obtained from accelerometers and microphones.
- Improve simulation accuracy through iterative model updating based on laboratory test results.
