大锻件 meaning in Chinese

heavy forging

Abstract : according to the related principle of forming precision andmicrostructure on the condition of deformation and thermodynamic parameters , hot forming process control of large forgings , such as retaining rings and crand - shafts , is investigated by means of computer simulation combined with thermodynamic and micro - simulation in this paper
文摘:本文采用热力模拟、微观模拟和计算机数值模拟相结合的模拟技术，根据变形条件、热力参数与成形精度和组织结构的相关性原理，以护环、曲轴大锻件为例，进行了热成形可控性的研究。
