摘要：

Topology optimization of cast parts involving parting surface position is one of the main challenges in engineering design. This work presents a study on topology optimization of cast parts considering various cases of parting surface position. Two casting constraint models for different parting surface position requirements are developed and evaluated. One is a variable parting surface model to achieve the optimal castable design and parting surface position. Another is a virtual parting surface model for generating the required castable desig...
