摘要
通过对白车身前舱减震器支座的两个冲压件改制成一个铝合金压铸件以实现汽车轻量化是一种可行的途径,并符合当前节能减排的要求。针对改制后的铸件模型,基于Procast对其进行压铸充型过程的模拟分析,同时结合合金熔液的流动状态及卷气情况进行结构优化。仿真结果表明,在合适的工艺参数下,该类零件可以达到满意的充型效果,对实际生产中实现汽车减重具有一定的指导作用。
It＇s a feasible way to achieve lightweight by merging two stamping parts of shock absorber support into an aluminum alloy die casting, which is in accordance with the current energy saving requirements. Filling processes of the restructured casting model is simulated by using the software Procast. Then combine the flow state of molten alloy with the entrapment air, a structural optimization is conducted. The simulation results show that satisfactory effect of filling process can be achieved if the process parameters are selected properly, and offer the actual production some guidance to achieve weight reduction of cars.
