摘　　要：本文利用微型计算机和数值模拟技术，模拟了６１０５柴油机曲轴的原始工艺及改进工艺后的凝固过程，预测出铸件中收缩缺陷位置与实际情况相吻合。按改进的工艺方案进行生产，使曲轴铸件缩孔、缩松废品率由原来的６％降到３％左右。The solidification process of the crankshaft castings for 6105 diesel engine under the conditions ofboth original and improving technological design has been simulated using microcomputer and numerical simulation technique, the location of shrinkage defects predicted by computer is coincided well withthat in the real castings,the reject rate of shrinkage cavity and porosity was reduced from 6% to 3%
