摘要
本文研究了消失模铸造干砂振动紧实的规律性,设计了测定干砂紧实的实验装置,得出了干砂振动紧实与振动参数及负压的关系。
This paper studies the law of compactibility of unbonded sand under vibration in EPC.The expriment set is designed and the conclusion which relative between com- pactibility of unbonded sand under vibration and vibrative parameters and negative pressuer.
