Moving Force Identification Studies II: Comparative Studies
Chan, Tommy H.T., Yu, Ling , Law, S.S. , & Yung, T.H. (2001) Moving Force Identification Studies II: Comparative Studies. Journal of Sound and Vibration, 247(1), pp. 77-95.
The theoretical background for four moving force identification methods has been presented in a companion paper. This part of the paper is an extension of the work to study the applicability of the four moving force identification methods. The parameters under study include the speed of vehicles, sampling frequency, axle-spacing-to-span ratio, and sensitivity towards noise. For the time domain method and frequency-time domain method, recommendation of the number of strain gauges is included. A comparison of the accuracy of the force identification using the four methods is given. Both illustrative and experimental results show that each method has its merits and limitations. It is found that the TDM gives the best results, but it is time consuming. Recommendations are given for each method to improve their performance and range of application. Further investigation would be to merge the four identification methods into a moving force identification system (MFIS).
Impact and interest:
Citation countsare sourced monthly fromand 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 theindexing service can be viewed at the linked Google Scholar™ search.
