Описание (английский):

Specifies a uniform method. Applies to data to be used for certain types of structural testing and data on vibration measured at the vehicle-occupant interface. Applies to original reports of measured data and to reports or other publications which assess, summarize, compare or compile measured data from original reports.

Abstract

Overview

Key topics and requirements

Scope and exclusions
- Applies to vibration data used for structural testing and vehicle‑occupant interface measurements.
- Not applicable to reporting transfer functions or other derived dynamic properties.
Essential information to report
- Measurement point and axis: clear location referenced to vehicle coordinate system or axle centre; transducer orientation.
- Total r.m.s. acceleration: calculated from time domain over same frequency range as spectral data; used as a cross‑check with frequency‑domain results.
- Stationarity: report statistical test result (smallest nominal significance level at which stationarity is not rejected).
Spectral analysis parameters (minimum)
- Analysis method (analogue or digital) and preprocessing filters (cut‑off frequency and slope).
- Resolution bandwidth (or proportional‑bandwidth description), duration of analyzed data, and statistical precision of spectral estimates (reported for 95% confidence).
- For swept analyzers: sweep rate and total analysis time.
- Additional processing steps and any detrending used.
Analog and digital specifics
- For analogue: filter class (octave/third‑octave), accelerometer sensitivity and natural frequency, mounting, and measurement range.
- For digital: sampling frequency, analysis frequency range, window function and correction factor, and algorithm type (FFT, mean lagged product, etc.).
- Instrumentation flow chart, calibration method and system gain.
Magnitude distribution reporting
- Zero‑mean instantaneous acceleration probability density normalized to r.m.s., plotted semi‑log (log probability axis). Include Gaussian reference curve and magnitude window width.
Preferred plotting formats
- Third‑octave/octave r.m.s. data: logarithmic scales (log‑log).
- PSD: linear‑linear recommended (log‑log acceptable for large ranges).

Applications and users

Who uses it
- Vehicle OEMs, test laboratories, vibration engineers, occupational health specialists, researchers and standards bodies.
Practical uses
- Preparing consistent test reports for structural/component testing, whole‑body and hand‑transmitted vibration studies, vehicle‑occupant interface assessments, inter‑lab comparisons, data compilation for research or regulation.
