The Wb weighting factor is defined in ISO Guidelines for the evaluation of the effects of vibration and rotational motion on passenger and crew comfort in fixed-guideway transport systems Status Ios Publication Date 16 October Cross References ISO The main script is: Your basket is empty.
Supports ISO Wh frequency weighting filter. The time domain method applies each factor to the appropriate bandpass filtered time history. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

ISO 2631 Matlab Scripts
An evaluation of the effect of exposure to vibration on humans is performed by weighting the root-mean of acceleration data transmitted via supporting structures.
The design and processing of data with a supported frequency weighting filter is accomplished in one easy step.
Supports BS Wg frequency weighting filters. The ISO Module supports all ten of these standard filter types as described below: The faster, easier way to work with standards. Sir, The frequency weighting that we apply for assessing human vibration, do I need to apply it separately in time domain or frequency domain? The resulting coefficients are in second order CASCADE form and are used to process the data with high numeric precision and stability.
The weighting factors can be applied either in the time or frequency domain. Sorry, your blog cannot share posts by email. Guidelines for the evaluation of the effects of vibration and rotational motion on passenger and crew comfort in fixed-guideway transport systems This document has been re-assessed by the committee, and judged to still be up 2361-4 date.
The desired filter 2361-4 are generated by converting the analogue filter specifications detailed in the supported standards into the digital domain using the bilinear transform method.
ISO Mechanical vibration and shock — Evaluation of human exposure to whole-body vibration. Knowledge Base List Archives Downloads. Optional frequency domain weighting curve display. Hi Bob, Thank you so much for this and your prompt reply. The bandwidth is one-third octave. In addition, the ISO Standard defines a frequency weighting curve for hand vibration and the British BS Standard defines a curve for activity interference.
