摘　　要：结合工厂实际生产条件 ,应用所开发的基于FT STAR的熔模铸造模拟软件 ,预测了气囊左下支座熔模铸造件的缩孔缺陷 ,将计算结果与实际检测结果进行了对比 ,证明计算结果能较好地反映实际情况 。Combining with spot conditions, shrinkage flaw of air camber support fabricated by investment casting were forecasted by a home-made solidification simulation soft. The forecast results were compared with the results of actual measurement. Both of the results agreed with each other, the reliability of the simulation soft of investment casting was validated.
