The ISO Standard describes weighting filters for combinations of sitting, standing and recumbant positions for the analysis of health, discomfort, perception and motion sickness.
DADiSP / ISO 2631
The main script is: It is important to us that you purchase the right document. An evaluation of the effect of exposure to vibration on humans is performed by weighting the root-mean of acceleration data transmitted via 263-14 structures.
The time domain method applies each factor to the appropriate bandpass filtered time history. The design and processing of data with a supported frequency weighting filter is accomplished in one easy step.
For example, to process acceleration data in Window 1 with an ISO Wk frequency weighting filter:. It is used for crew and passenger exposure to vibration in rail vehicles, or fixed-guideway 26631-4 systems.
The desired filter coefficients are generated by converting the analogue filter specifications detailed in the supported standards into the digital domain using the bilinear transform method. Wk for the Z axis or vertical direction, Wd for the X and Y axes, or horizontal direction, and Wf for motion sickness.
Guidelines for the evaluation of the effects of vibration and rotational motion on passenger and crew comfort in fixed-guideway transport systems. The bandwidth is one-third octave.

Sir, The frequency weighting that we apply for assessing human vibration, do I need to apply it separately in time domain or frequency domain? Supports Isl Wg frequency weighting filters. The resulting coefficients are in second order CASCADE form 2613-4 are used to process the data with high numeric precision and stability.
Here is to the best software support team — ever! You may experience issues viewing this site in Internet Explorer 9, 10 or In addition the ISO Wh and British Io Wg frequency weighting filters are included to provide a complete, standards-based frequency weighting solution. Additional frequency weightings defined for the special cases of seat-back measurements, rotational vibration and vibration under the head. Optional frequency domain weighting curve display. In addition, the ISO Standard defines a frequency weighting curve for hand vibration and the British BS Standard defines a curve for activity interference.
