Two Round Robin Exercises On Road Transportation Data.

This paper presents the results of the first and second round robin exercises 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.

The main aim of the first round robin exercise was to identify the range of methods used for the assessment of road transportation dynamic data. However, the round robin exercise 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 arose in the quantitative comparisons.

The second round robin exercise was intended to address a specific aspect identified as a concern in the first exercise. One of the surprising findings of the first exercise was the variations in methods the participants used to identify and quantify shocks from within the background vibration. This variation was reflected in a poor success rate at identifying and quantify the shocks. The late Karl-Heinz Hansen of the Gesellschaft fur Umweltsimulation (GUS) proposed an exercise to both specifically investigate this aspect and as a vehicle for improving vibration analysis skills. This proposal was subsequently expanded by the CEEES Transportation Stresses Working Group. The proposed aims and objectives of the second exercise were;

  • To evaluate the methods in current use to recognise and quantify shocks when embedded in vibration of the type expected from the transportation environment.
  • To quantify the variations arising from the use of different methodologies. In particular to identify the degree of operator experience and skill required for the different methods.
  • To generate progressively more difficult test cases against which experience and skill can be improved.
