摘要：

According　to　the　configuration　and　mechanical　characteristics　of　piezoelectric　actuators,　the　bidirectional　piezoelectric　variable　friction　control　device　that　can　produce　the　control　force　in　2　orthogonal　directions　with　the　fail-safe　ability　was　presented.　The　relationship　between　the　control　force　and　the　input　voltage　for　this　control　device　is　presented.　The　performance　test　of　the　control　device　was　processed.　The　vibration　control　experiment　of　the　structure　with　the　control　device　based　on　the　sweep　sine　shaking　table　was　carried　out.　The　experimental　results　show　that　the　control　device　has　stable　mechanical　properties,　can　quickly　produce　the　semi-active　control　force,　has　the　outstanding　control　efficiency,　and　has　the　satisfactory　control　efficiency　when　the　piezoelectric　actuator　of　this　control　is　failed,　which　indicates　the　control　has　the　fail-safe　function.
