Abstract: The present work deals with the topic of service loads for motorcycles resulting from road excitation. The aim is to create virtual test tracks that can be used representatively for load assumptions. First, different methods from the field of durability engineering were reviewed that centre around the topic of damage equivalency. The methods were evaluated in terms of applicability for virtual test tracks. With an omission approach, a novel method was found to detect relevant track segments for different use cases. The method was successfully applied to create virtual test tracks based on measurements of real tracks with laser scanners. With the proposed method the length of the test tracks and data amount could be decreased by approximately 70%. The gained perceptions enable a faster definition of design loads while additionally saving costs and reducing the amount of data during the early stages of development.
