Optimization of Component Structural Parameters and Strength Redundancy Configuration for Active Remanufacturing
In order to meet the optimization needs of multi-parameter indicators such as component stress,life and energy consumption in the process of designing for active remanufacturing,a method for component structure parameter optimization and strength redundancy configuration for active remanufacturing is proposed.The process framework for optimizing part structure parameters and configuring strength redundancy is described,the functional model between structural parameters and static stress,fatigue life,life cycle energy consumption and cost is constructed,and the TOPSIS method is used for multi-objective optimization of the structural parameters.On this basis,the average time energy consumption and average time cost corresponding to the optimal structural parameters are used as the evaluation indices.After finite repeated gambling,the active remanufacturing timing is determined,and the strength redundancy configuration is realized by strength redundancy factor resolving.Taking a type of six-cylinder engine crankshaft as an example,the main shaft radius,arm width and transition fillet radius are selected as key optimization parameters to carry out structural parameter optimization and strength redundancy configuration,and the effectiveness of the method has been verified.
