A Round Robin Exercise On Road Transportation Data.

This paper presents the results of a round robin exercise recently undertaken under the auspices of the Mechanical Environments Technical Advisory Board (then the transportation stresses working group) of the Committee of European Environmental Engineering Societies (CEEES). The document is a 12 page paper generated in 2001.

A total of 22 agencies from 6 different European countries participated in this work. Each participant undertook analysis of an identical piece of measured data. The majority of the participants reported analysis of the data, many also derived test severities. This paper presents a basic comparison of the responses and assesses the results.

The concept of the CEEES road transportation round robin exercise arose from an earlier survey. That survey polled various European agencies for their views on aspects of road transportation vibration and shock. A significant percentage of the 33 agencies, who responded, considered that existing specifications relating to road transportation were inadequate. Moreover, a number felt that the use of such specifications often resulted in overtesting. The survey also suggested that no general consensus existed as to how improved test severities could be derived. Taken together, these findings indicated the benefits of a round robin exercise that would both determine the range of methodologies in use, and also compare their respective results.

The aim of the round robin exercise was to identify the range of methods in use to assess road transportation dynamic data. It was also intended to quantify any variations arising from the use of different methodologies. The intent was that each participant should utilise what ever method they considered appropriate. To this end the requirements for active participation were set so as not to influence the participant's choice of approach. In practice this meant imposing relatively few constraints. As a consequence some limitations are imposed on the quantitative comparisons.
