Dataset of Full-Scale Structural Strain, Vibration, and Acoustic Measurements from a Passenger Rail Vehicle Operating Under Service Conditions

This repository contains a full-scale experimental dataset of structural strain, vibration, and acoustic responses collected from an executive-class passenger rail vehicle operating on a 1067 mm narrow-gauge railway network in Indonesia. The measurements were acquired under representative operating conditions including maximum speed (100 km/h), acceleration, deceleration, inclined curve, declined curve, and sharp curve manoeuvres. The dataset was obtained using synchronized multi-sensor instrumentation comprising: Ten three-element rosette strain gauges installed on the carbody, coupler assembly, and bogie structure. One triaxial accelerometer and two uniaxial accelerometers mounted at representative vehicle locations. Five Class-1 free-field microphones positioned inside the passenger cabin. The repository includes raw and processed measurement data covering three physical domains: Structural strain measurements recorded from rosette strain gauges. Vibration measurements in longitudinal, lateral, and vertical directions, including frequency-domain representations. Acoustic measurements including sound pressure level (SPL) data and one-third octave band spectra. Supporting materials are also provided, including sensor layouts, instrumentation schematics, metadata files, channel descriptions, acquisition parameters, and illustrative figures describing the experimental configuration. This dataset is intended to support numerical model development, calibration, verification, and validation activities in railway engineering. Potential applications include finite element modelling, structural dynamics, vibration analysis, fatigue assessment, noise and vibration (NVH) studies, vibro-acoustic simulations, digital twin development, machine learning applications, and comparative benchmarking investigations. The dataset provides a synchronized multi-domain experimental reference acquired under real operating conditions and may be reused for research and educational purposes.
