Development and Application of Integrated Computational Platform for Investment Casting Processes
Currently,the optimization of investment casting processes heavily relies on empirical trial-and-error meth-ods,resulting in long optimization cycles,high labor costs,low operational efficiency,and a lack of algorithmic optimi-zation.Therefore,an integrated computing platform for investment casting processes was developed based on the Pro-CAST finite element simulation software and multitasking batch processing technology,which integrates various func-tions,including Design of Experiments(DOE)algorithms,finite element simulation,automatic extraction of result data,surrogate model construction,and collaborative multi-objective optimization.Taking a turbine guide vane as example,integrated optimization of casting process-defect simulation was realized with shrinkage as target value,pour-ing temperature,ambient temperature and thermal emissivity as variables.The efficiency of integrated computing plat-form is improved by 91.66%compared with that of traditional simulation optimization.
