Report on Vehicle Vibration Machine and Dynamics Analysis (ME Course)

This engineering report delves into the analysis of vehicle vibration and dynamics, focusing on the impact of road roughness on vehicle suspension systems. The study employs data collected using an ADXL sensor and a data acquisition unit, examining vibrations in the X, Y, and Z axes. The report explores the resonance vibration effect, vehicle suspension measurement, and vibration propagation. The research utilizes MATLAB for data analysis, including the implementation of the Short Time Fourier Transform (STFT) algorithm. The report discusses the vehicle's damping element, the influence of road surface irregularities, and the application of relevant Australian standards. The data analysis covers graphical illustrations of collected datasets, and the analysis is based on the standards. The report provides a comprehensive overview of the methodology, data analysis, and results, offering valuable insights into the factors influencing vehicle vibration and dynamics.
