The deviation in wall thickness caused by core shift during the investment casting process significantly impacts the strength and service life of hollow turbine blades.To address this issue,a core shift limitation method is developed in this study.Firstly,a shift model is established based on computational fluid dynamics and motion simulation to predict the movement of the ceramic core in investment casting process.Subsequently,utilizing this model,an optimization method for fixtur-ing layout inside the refractory ceramic shell is devised for the ceramic core.The casting experiment demonstrates that by utilizing the optimized fixture layout,not only can core shift during the invest-ment casting pouring process be effectively controlled,but also the maximum wall thickness error of the blade can be reduced by 42.02％.In addition,the core shift prediction is also validated,with a prediction error of less than 26.9％.
