It aims to generate a simplified model to release computational loading while maintaining model fidelity. The dynamics of the multi-physical system can be constructed based on a unified bond graph approach. This EO-MSA approach eliminates those bond graph elements which influence the system behaviour insignificantly in the mathematical model. This study proposes two newly-defined indices, dynamic similarity ( DS), and model similarity index ( MSI), to evaluate the similarity of candidates which are order reduced. Ten error-dynamics modules are mathematically constructed and structurally classified for both the DS and the MSI. The reduced model with minimum MSI can be determined using this approach. Quarter-car simulation results demonstrate that this EO-MSA approach is capable of reducing system complexity while maintaining fidelity with satisfactory tolerance. <\/jats:p>","DOI":"10.1177\/0959651811409490","type":"journal-article","created":{"date-parts":[[2011,9,24]],"date-time":"2011-09-24T06:55:23Z","timestamp":1316847323000},"page":"56-69","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["An element-oriented model simplification algorithm based on dynamic similarity"],"prefix":"10.1177","volume":"226","author":[{"given":"Y H","family":"Hung","sequence":"first","affiliation":[{"name":"Department of Industrial Education, National Taiwan Normal University, Taipei, Taiwan"}]},{"given":"C H","family":"Wu","sequence":"additional","affiliation":[{"name":"Electric Propulsion and Control Department, Industrial Technology Research Institute, Hsinchu, Taiwan"}]},{"given":"C W","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Power Mechanical Engineering, National Tsing Hua University, Hsinchu, Taiwan"}]}],"member":"179","published-online":{"date-parts":[[2011,9,23]]},"reference":[{"key":"bibr1-0959651811409490","doi-asserted-by":"publisher","DOI":"10.1243\/0959651021541444"},{"key":"bibr2-0959651811409490","doi-asserted-by":"publisher","DOI":"10.2514\/3.25416"},{"key":"bibr3-0959651811409490","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfranklin.2005.01.008"},{"key":"bibr4-0959651811409490","doi-asserted-by":"publisher","DOI":"10.1016\/0016-0032(94)90003-5"},{"key":"bibr5-0959651811409490","doi-asserted-by":"publisher","DOI":"10.1016\/0005-1098(80)90052-7"},{"key":"bibr6-0959651811409490","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.1981.1102568"},{"key":"bibr7-0959651811409490","doi-asserted-by":"publisher","DOI":"10.1016\/0005-1098(85)90101-3"},{"key":"bibr8-0959651811409490","first-page":"6287","volume":"195","author":"Aarti S.","journal-title":"Comput.
