Synthetic　microwedge　adhesive　inspired　by　gecko　has　great　advantages　in　its　prominent　adhesion　property　and　controllability.　Clarifying　the　adhesion　mechanism　is　significant　for　designing　structure　and　enhancing　performance.　However,　previous　investigations　have　not　given　a　thorough　exposition　in　the　adhesion　mechanism　of　microwedge　structure,　especially,　the　complex　relationship　among　shear　load,　contact　area,　and　normal　adhesion.　In　this　paper,　aiming　to　clarify　the　relationship　mentioned　above,　a　novel　microwedge　adhesive　representation　combined　profile-constructed　elastic　beam　model　with　a　peel　zone　radius　exact-solved　cylindrical　Johnson-Kendall-Roberts　(JKR)　model　is　proposed.　First,　the　contact　area　can　be　obtained　by　reconstructing　principal　profile　to　the　curved　neutral　surface　based　on　the　elastic　beam　model　under　different　shear　loads.　Then　the　cylindrical　JKR　model　with　exact-solved　fitting　radius　of　peel　zone　is　formulated　to　establish　the　relationship　between　shear　load　and　normal　adhesion　of　a　single　microwedge.　Further,　the　effective　contact　between　neighboring　microwedges　is　considered　to　constrain　the　single　microwedge　deformation.　Moreover,　the　microwedge　array　model　takes　into　account　the　influence　of　normal　movement,　which　is　expressed　with　a　correction　factor　based　on　comparison　of　theoretical　analysis　and　measurement　results.　Finally,　the　model　is　verified　with　the　simulation　and　the　experimental　measurement　of　two　customized　apparatuses.
