| Summary: | Planet carrier is one of the key components in the main reducer of earth pressure balance shield. In order to meet the requirements of lightweight design,the smallest of volume and minimum of rotary inertia multi-objective optimization model is established by considering its dynamic and static characteristics requirements.The design variables are taken correlation analysis under circumstance without non-sensitive factors to improve design efficiency.Using enhanced central composite design to get the proper design point,and the design point is simulated and analyzed by using the finite element method,then,a high-precise Kriging response surface model is established according to the simulation results.Sample points distributed evenly are taken out by using Shifted Hammersley sampling technology.After balancing pros and cons of the points,two Pareto optimal solutions are obtained under certain constraints.The volume and rotary inertia are decreased by 10% or more after optimization and the design target of planet carrier in volume and rotary inertia is achieved. |
