This　paper　focuses　on　the　nonlinear　vibration　and　snap-through　behavior　of　bistable　cantilever　shell　under　in-plane　foundation　excitation.　A　combination　of　experimental　and　finite　element　analysis　methods　are　used　for　an　in-depth　exploration.　The　experimental　setup　is　built　to　accurately　simulate　the　in-plane　foundation　excitation　environment　and　measure　the　nonlinear　responses　of　bistable　cantilever　shell.　By　adjusting　excitation　parameters,　the　dynamic　behavior　of　the　structure　under　different　conditions　is　systematically　observed,　especially　the　snap-through　process　from　one　stable-state　to　the　other.　A　corresponding　finite　element　model　is　established　based　on　ABAQUS　software　to　verify　the　accuracy　of　the　experimental　results　and　further　understand　the　motion　mechanism,　which　takes　into　account　factors　such　as　material　nonlinearity　and　geometric　large　deformation.　By　comparing　the　experimental　results　with　the　simulation　data,　a　high　degree　of　consistency　is　exhibited.　This　not　only　verifies　the　reliability　of　the　experimental　method　but　also　demonstrates　the　accuracy　and　applicability　of　the　established　FEA　model.　The　nonlinear　vibration　and　snap-through　behavior　of　bistable　cantilever　shell　are　quite　sensitive　to　the　excitation　levers.
