7-DOF Model for NVH Analysis

This paper presents a 7-degree-of-freedom model for Noise, Vibration, and Harshness (NVH) analysis and provides an in-depth exploration of simulation implementation using Simulink. The model incorporates parameter reconfiguration capabilities to better understand its dynamic behavior and performance impacts. Through MATLAB scripting integration, users can programmatically adjust mass, damping, and stiffness parameters to analyze their effects on vibration modes and acoustic responses. The implementation features state-space modeling techniques with real-time parameter tuning through Simulink's workspace variable interface. These investigations enable better understanding of the interactions between noise, vibration, and stiffness characteristics, facilitating more effective application of these concepts in design optimization and engineering practices. The modular Simulink architecture allows for easy integration of additional subsystems and custom transfer function blocks for extended analysis.
