Structural Design Optimization of the Rotary Table of a Floor Type Boring Machine for Minimum Weight and Compliance by using GA
Recently needs of extra-large floor type boring machines have been increased according to super-sizing ships and aircrafts including wind turbines.The rotary table of a supersize floor type boring machine to be developed in this study can support ultra heavyweight workpieces more than 200 tons and be rotated with a speed of 300 deg/min.Therefore,it is designed as a high rigidity structure and requires high rigidity bearings.Thus,hydrostatic bearings are used in this rotary table.For optimizing the rotary table of a floor type boring machine as a lightweight and high rigidity structure,an optimized design is performed using an FEM structural analysis and a genetic algorithm (GA).As a result,it represents a decrease in weight 22.2% and an increases in rigidity 8.56% compared to that of the conventional method based on empirical design.
