Abstract
Various researches have contributed to the elaboration of standards like the ISO 2631 or the
British Standard 6841. One important point regarding these standards is that they give a very precise description of comfort criteria but they can be applied with an infinity of different protocols regarding sensor position, subjects number and type, road signals type, subject posture The aim of the SCOOP project was to define a specification for the quantification of seat vibration comfort allowing exchange of data between several partners. This specification, called SVCTP (Seat Vibration Comfort Testing Procedure) doesnt only give criteria (those of the ISO2631 [1], BS6841 [2] and also new ones are used) but also a very precise protocol.
In this paper we will show how the different SCOOP work packages results have contributed to the elaboration of this procedure.
For that aim, we will particularly focus on the following points:
- Sensor position and data exchange format
- Repeatability validation
- Effect of the subject and the type of road
- Effect of the subject posture
Then we will highlight the interaction existing between physical seat parameters, vibration criteria measured with human subjects and static comfort criteria. This analysis will give guidelines for the definition of boundary conditions for seat optimisation.
