The　exceptional　mechanical　properties　of　composite　structures　have　gradually　sparked　the　interest　of　researchers.　However,　factors　such　as　lightweight　and　eco-friendliness　are　also　crucial　while　meeting　the　requirements　of　mechanical　properties.　This　paper　investigates　the　mechanical　responses　of　corrugated　sandwich　structure　through　three-point　bending　experiments　and　numerical　simulations.　The　corrugated　sandwich　structure　is　composed　of　two　aluminum　alloy　sheets　and　a　bamboo　scrimber　core.　ABAQUS/Explicit　was　used　for　numerical　simulation,　and　the　simulation　results　are　compared　with　the　experimental　results.　The　results　indicate　that　there　is　a　good　degree　of　agreement　between　the　experiment　and　the　simulation,　which　validates　the　feasibility　and　accuracy　of　the　numerical　modelling.　Based　on　this,　the　sandwich　structure　with　different　layup　direction　were　compared　to　reveal　the　bearing　capacity　and　energy　absorption　mechanism.　The　orthogonally　corrugated　sandwich　structure　exhibits　the　optimal　mechanical　performance.　The　graphical　user　interface　parameterized　modeling　scripts　for　ABAQUS　was　developed,　enabling　an　analyze　of　the　influence　of　different　corrugation　angles　and　working　condition　on　the　mechanical　properties　of　corrugated　sandwich　structure.　The　optimal　structure　and　optimal　working　condition　for　the　sandwich　corrugated　structure　were　determined.　The　obtained　results　will　provide　a　foundation　for　the　engineering　applications　of　the　corrugated　sandwich　structure.
