主 题:Geometrical nonlinearity Integrated optimization Lithium batteries layout Periodic structural configuration Solar-powered drone Wing beam structure
摘 要:The purpose of this paper is to demonstrate an integrated optimization scheme for a solar-powered drone *** a primary beam in the wing of large aspect ratio,where 100 lithium batteries are *** the proposed integrated optimization,the batteries are considered here as parts of the load-carrying *** corresponding mechanical behaviors are simulated in the structural design and described with *** batteries layout and the structural topology are then introduced as mixed design variables and optimized simultaneously to achieve an accordant load-carrying *** nonlinearity is considered due to the large *** periodic structural configurations are tested in the optimization in order to meet the structural manufacturing and assembly *** optimized designs are rebuilt and tested in different load *** the same structural weight,the global mechanical performances are improved greatly compared with the initial design.
