Product Design Improvement Using Human-Computer Interaction Method Based on Modal Analysis
China Astronaut Research and Training Center, Beijing, China
A new kind of product design improvement method was proposed, which was mainly based on modal analysis using human-computer interactive way. And it was used in design improvement of an aerospace assembly to verify the effectiveness. The method made full use of the advantages of human and computer in product design and the work was mainly focused on modal analysis by computer and structure modification by human-computer interaction method. The final design got a better solution than the initial design as the results showed that the base frequency increased by 34.7% from 43.2Hz to 58.2Hz after design improvement and the vibration feature improved a lot. Also the experimental results were close to the simulation results with the relative error was 2.5%. The human-computer method can save cost and time and can provide a reference for other design of new products at the same time.
