The Research On The Determination Of The Main Path Of Force Transfer In The Wing Based On Structural Topology Optimization

The existing wings of the aircrafts are designed according to the designers'experiences and the type of the aircrafts. The forms of the wings of the aircrafts are confirmed in the design scheme, so the optimization design is constrained in the optimization procedure. In view of the problems above, the design scheme is mentioned which is about that use the main path of force transfer to get the result before the confirmed structure.Take the model of the aircraft as the research object, put forward the method of confirm the path of the force transfer in the structure of the wings base on the topology optimization. After the method of the topology optimization, the material distribution, is also called the path of the force transfer, can be taken as the basis of the wing design.The path of the force transfer cannot be picked as the research object to analyze in the processing of the topology optimization. The paper solves this problem with C# program, extracting and processing the results from the software analyzes in order to facilitate remodeling, to achieve structural design purposes.We take the new model of the path of the force transfer to reanalyze, including the modal, stress, and the stiffness to verify whether the form of the structure is the form of the path of the force transfer.The tasks above can be taken as a process of the structural optimization design, and used in the conceptual design. This method can not only find out the form of the path of the force transfer, but also find the problems in the earlier process of the structure design. The method can be used in the conceptual design and preliminary design of the structural layout design, it is also has reference value and guiding role for the engineering practice.
