摘要：

In　Real-Time　Dynamic　Substructure　(RTDS)　testing,　the　easily　modeled　part　is　simulated　numerically　and　the　rest　part　is　tested　physically,　so　that　the　capacity　of　the　existing　facilities　can　be　enhanced　indirectly.　The　stability　caused　by　the　dynamics　of　transfer　system　and　specimens　are　the　challenge　for　the　implication　of　RTDS　testing.　In　previous　research,　the　coupling　dynamics　of　transfer　system　and　specimens　were　neglected.　In　this　paper,　a　dynamic　coupling　model　was　established　for　actuator　and　shaking　table　respectively.　To　consider　the　transfer-system-specimen　interaction　in　the　analysis　of　RTDS　stability,　a　novel　analysis　method　was　developed　and　verified　through　analytical　and　experimental　comparison.　Using　the　developed　method,　the　influence　of　transfer-system-specimen　interaction　on　the　stability　of　actuator　and　shaking　table　RTDS　was　discussed.　The　analysis　results　show　that　the　transfer-system-specimen　interaction　is　sometimes　beneficial　and　sometimes　detrimental　to　RTDS　stability.　©　2016,　Engineering　Mechanics　Press.　All　right　reserved.
