Vehicle Vibration Machine and Dynamics Analysis Report, Engineering

This report provides a detailed analysis of vehicle vibration and dynamics, investigating the impact of road unevenness on vehicle performance. The study focuses on the vehicle's suspension system, internal combustion engine, and the collection of data using an ADXL sensor and data acquisition unit. The report explores the effects of resonance vibration, which amplifies vibration responses. The methodology includes data collection at various speeds on different road surfaces, with the data analyzed using MATLAB R2018b software and methods like the short-time Fourier transform (STFT). The analysis covers vibration accelerations in orthogonal axes (X, Y, and Z) and the determination of vibration parameters. The report also includes data analysis and discussion, presenting graphical illustrations of the collected data and comparisons with standards like AS 2670.1-2001. Overall, the report aims to determine the vibration machine and dynamics of a vehicle in motion.
