Description
Summary:The deployable hindwings of certain coleopterans are their major flying components, and the veins supporting their hindwings play a significant role during flight; this knowledge is critical for designing bioinspired deployable micro air vehicles (MAVs). Therefore, the effects of microfluid (hemolymph) in the veins of beetle deployable hindwings are investigated in this paper. Microstructures are derived from hindwing cross sections and the nanomechanical properties of the hindwings and veins of the Asian ladybeetle Harmonia axyridis (Coleoptera: Coccinellidae). Based on these microstructures, three three-dimensional coupled models are established, including solid veins, hollow veins, and hollow veins filled with hemolymph. Then, the mechanical properties and vibration characteristics of the models are investigated. The torsional veins are affected more significantly by hemolymph when bending. This work will be helpful in designing new biomimetic deployable MAVs.
