The　variant　wing　can　adapt　to　more　complicated　operating　environment.　There　often　need　large　thickness　deformation　and　wingspan　change　in　the　process　of　wing　deformation.　Meanwhile,　the　deformation　process　should　not　affect　other　components,　which　requires　that　both　the　wing　structure　and　the　outer　panel　cover　have　the　function　of　zero　poisson＇s　ratio　and　large　deformation.　For　this　reason,　this　work　designed　a　two-dimensional　poisson＇s　ratio　structure　based　on　the　topology　optimization　and　variable　density　method.　Then,　optimization　design　method　was　adopted　to　meet　the　demand　of　zero　poisson＇s　ratio　and　large　deformation　of　wing　cover.　Furthermore,　the　equivalent　elastic　tensor　of　zero　poisson＇s　ratio　structure　with　large　deformation　was　predicted　using　energy　homogenization　method,　and　the　mechanical　properties　of　zero　poisson＇s　ratio　structure　were　verified.　Finally,　numerical　simulation　method　was　conducted　to　predict　the　mechanical　properties　of　zero　poisson＇s　ratio　wing　covering　lattice　structure.　To　summarize,　a　kind　of　wing　cover　structure　with　zero　poisson＇s　ratio　and　large　deformation　in　this　study　was　obtained　and　the　application　of　this　structure　in　aerospace　was　also　demonstrated.　©　2023　Institute　of　Physics　Publishing.　All　rights　reserved.
