In　this　paper　is　introduced　a　design　of　two-dimensional　dynamic　test　system　for　mechanical　performance　of　biosoft　tissue.　The　external　force　exterted　on　the　tissue　and　deformation　of　the　tissue　are　measured　to　reflect　dynamic　properties　of　soft　tissue.　Experiments　were　carried　out　using　rabbit　abdomen　as　the　object.　This　system　was　used　to　measure　hysteresis,　relaxation　and　creeping　characteristics.　The　feasibility　of　the　system　was　proved.
