Topology Optimization Design Method Of Folding Wing Deformed Structure

The morphing aircraft has the performance of appearance and a wide range of metamorphosis.The flight of folding wing,swept back and other deformable body needs to support the structural deformer to realize the change of wing or long movement.For deformable structures,it’s not the case now.Because of the lack of CAD tools,the amount of work for the structural design of deformable body aircraft affects the development speed of aircraft.As a computer aided structural design method of selecting maturity,topology optimization technology can effectively improve the structure and weight.The current topology optimization technology is very important for the effect optimization of deformable structures.In this paper,through the optimization method,the deformable structure is designed.In order to solve the design problem of deformable structure,a mapping method of element matrix which can be linked is proposed in this paper;Then it is introduced into the asymptotic model to construct the model method model of obese people for deformable structure;Then,the element flexibility of the model is derived,and the optimized variant model is used to solve the problem.A topology optimization program is developed for the plane beam structure,and the structure state of the structure is verified by using the program to optimize the plane arm;Then,the design domain and working condition of the deformable girder in the folded wing deformation section of the ribbed plate are analyzed,and the optimization design is continued,and the optimal structure of the deformable girder in the folded wing deformation section of the traditional ribbed plate is obtained.A program for topology optimization of three-dimensional deformable structure is developed,and the effectiveness of the program is verified by using a flexible cantilever structure.Different shape optimization results are compared by the topology optimization results and the method proposed in this paper.The advantages and necessity of topology optimization method for deformable structures provide a new idea and method for the design of deformable structures.
