Lightweight simulation analysis of unmanned container transport vehicle frame based on sensitivity analysis
In order to improve the economy and reliability of unmanned aerial vehicle consolidation vehicles,the finite element model of the frame of unmanned container transport vehicle was established,and the strength,stiffness and modal performance of the frame were analyzed.Through the sensitivity analysis of frame compliance,mass and first-order mode,the design variables of frame optimization were selected.The size optimization model was established by HyperMesh module.On the premise of satisfying the strength,stiffness and first-order modal performance,the optimization design of the frame was carried out with the objective of minimizing the mass.The results showed that the weight of the frame was reduced by 10%and the performance requirements were met.The method can provide a certain reference for the lightweight design of the frame.
