Parametric Studies of Moving Axle Load Identification

Yu, Ling & Chan, Tommy H.T. (2001) Parametric Studies of Moving Axle Load Identification. In Journal of Sound and Vibration, American Society of Mechanical Engineers (ASME), Pittsburgh, PA, DETC2001/VIB-21524.


This study addresses the effects of various parameters on moving axle load identification when vehicles move across a bridge. Main emphases are placed on valuation of two solutions, pseudo-inverse (PI) and Singular value decomposition (SVD) solutions, to an over-determined set of equations established under the time domain method (TDM) and frequency-time domain method (FTDM). The effects of vehicle-bridge system parameters and of measurement system parameters on the TDM and FTDM are also investigated. Assessment results based on experiments in laboratory show that the TDM is a better and non-sensitive method. The SVD technique can effectively improve identification accuracy when using TDM and FTDM particularly in the case of the FTDM.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
