利用ADINA/ADINAT.CADAM-3DMESH及FEMB等计算机非线性有限元软件包对488铝缸盖铸件凝固过程进行数值模拟取得成功。1992年12月18在长春通过鉴定。 我国汽车铝缸盖生产目前大都采用低压铸造工艺,废品率为15％～25％,生产效率低。一汽为加速上轻型轿车的进度,对引进的机型488中最复杂零件,高强度、高致密性、高精度和薄壁铝缸盖大 The numerical simulation of the solidification process of 488 aluminum cylinder head casting was successfully carried out by using the computer nonlinear finite element software package ADINA / ADINAT.CADAM-3DMESH and FEMB. December 18, 1992 passed the appraisal in Changchun. At present, China’s automobile aluminum cylinder head production mostly adopts low-pressure casting process, the rejection rate is 15% ~ 25% and the production efficiency is low. FAW accelerated the progress of the light sedan, the introduction of the most complex 488 models of parts, high strength, high density, high precision and thin aluminum cylinder head large
