Analysis on the Improvement of the Defects of Alar Low-Pressure Casting of Cylinder Head

通过光弹性实验及有限元计算，对起重运输机械中应用普遍的圆环链的受力情况进行了分析计算，指出危险截面的所在位置，对提高圆环链的质量性能提供了理论依据。

The paper analyzes the primary defects of alar low-pressure casting of cylinder head.It expounds on the cause of defects and the preventive.It points out the new avenues of use for press casting to instead of low-pressure casting to improve the quality of cylinder head pressure casting.
