To　protect　movable　cultural　relics,by　shaking　table　tests　oscillation　responses　of　museum　free-standing　cultural　relics　under　earthquakes　were　studied.Based　on　actual　sizes　of　a　museum　showcase,a　1:1　scale　model　was　built　whose　bottom　was　fixed　on　the　shaking　table.A　bronze　cultural　relic　was　put　in　the　showcase　by　free-standing　mode.By　white　noise　excitation　frequency　distributions　of　the　showcase　were　obtained;By　inputting　3　different　types　of　earthquake　waves　(El-centro　wave,Taft　wave　and　Artificial　wave　of　11　site　classification)　with　different　intensities　(0.1g,0.2g　and　0.4g　of　peak　ground　accelerations),seismic　responses　of　both　showcase　and　relic　were　studied,　their　damage　types　were　discussed,　displacement　as　well　as　acceleration　response　curves　of　typical　positions　were　analysed　as　well.Results　show　that　prominent　frequency　ingredients　of　the　showcase　are　between　30-40Hz,which　are　far　from　those　of　input　earthquake　waves,thus　the　showcase　is　not　damaged　seriously;while　for　the　relic　when　input　earthquake　intensity　is　low,its　main　damage　symptom　is　oscillation;when　earthquake　intensity　increases,the　oscillation　response　becomes　very　serious　and　the　relic　is　prone　to　overturn　and　get　destroyed.
