摘要：
In view of the piston flaw occuring in manufacturing process, the operation condition of the piston with flaw was analyzed by means of computer-aided engineering (CAE). in combination with testing. The results show that the multi-pinhole defects can result in more serious stress concentration; the oval shrinkage defects has a little effect on the structural stress level; a few structure change of the cooling oil cavity could decrease the oval shrinkage defects.
