Optimization of Complex Structure Based on Human-Computer Interaction Method
To solve the problem of structural optimization of complex structure under dynamic response constraints, a human-computer interaction method was proposed combined with advantages of human and computer in structural optimization, and being used in structural optimization of an aerospace assembly to verify its practicability and effectiveness. The method was mainly based on two steps: topology optimization by human-computer interaction and size optimization by computer. The aerospace assembly after structural optimization based on the method could satisfy the dynamic environment requirement and the results showed that first integral vibration frequency raised 41.1 % and magnification of acceleration dropped 25.2 % while the mass remained essentially unchanged. Also the experimental results compared with the simulation results showed that the relative error was less than 5 %, which proved the effectiveness of the simulation design. The human-computer interaction method might provide a reference for similar products not limited to aerospace field.
