The OROS Body Vibration tool allow you to evaluate the affect of vibration on the human body according to standards ISO 2651 and ISO 5321. These standard define measurement practice and vibration signal analysis to evaluate the affect on health and and comfort of environmental and equipment vibrations on the Human body.

The ISO2651 describe the affect of vibration on the whole-body in transportation system, and the ISO5321 the affect of vibration on hands and arms when manipulating machine-tools or vibrating objects. In the following, we will see how to use OROS to evaluate these effect.


This OROS toolkit operate in post analysis mode and will help you to calculate weighted signal of acceleration with the filters and specific indicators both defined in the standards.



Download

Download the program here (version from 04/11/2020) : https://orossas.sharepoint.com/:u:/g/support/EU4wYMKICt1GoI06CuzGsAYBzit5aFCoAt7WC0RoHchAmA?e=dVc7Od

How to use

  1. Launch NVGate

  2. Launch OROS_BodyVibration_Tool.exe

  3. Open a project in NVGate
  4. File:Open project manager.png
  5. In the tool, Click on list measurement to list all the measurement present in the project (only the measurement where the signal files are actually on the disk will be displayed. Ensure you have downloaded signal from the OR3X disk)

  6. Add the measurement you want to analyse in the "selected list" area (you can select several measurements) using the ">>" button. Use the "<<" button to remove file if needed.

  7. Select the weighting you want to apply on the time signal

  8. Select the weighting you want to apply for each direction X, Y and Z used for the indicators

  9. Select the indicators you want to calculate

  10. Click on "Start Processing"

  11. The processing is completed when a the following pop-up window appear. The results ans weighted signal have been generated in the current NVGate project. See the next sections for details.
