Multi-objective Quality Optimizations of Automotive Air Filter Installation Cover based on Conformal Cooling
A finite element analysis model for the installation cover of automobile air filters was established to address the problems of excessive warping deformation and low production efficiency caused by uneven cooling due to the complex structure of the installation cover.The maximum warping deformation of the installation cover and the time to reach the part ejection temperature were taken as optimization objectives to improve product quality and production efficiency.Firstly,based on the self-built cooling water circuit,a finite element analysis model for injection molding simulation of the installation cover was established.Secondly,the optimal Latin hypercube sampling method and second-order response surface model were applied to establish the functional relationships between injection molding process parameters,the time to reach the part ejection temperature and the maximum warpage deformation.Finally,applying the Longhorn whisker algorithm,the optimal combination of process parameters that met the requirements of injection molding quality was obtained,improving the production efficiency and product quality of automotive engine air filter installation covers.The results show that the optimized time to reach the part ejection temperature is 123.4 s,which is 47％lower than that before optimization.The maximum warpage deformation after optimization is 1.554 mm,which is 7.5％lower than that before optimization.
