摘　　要：以垂向减震器座为例,采用砂型铸造工艺,设计了两种浇注系统方案,利用ANSYS分析软件分别对垂向减震器座铸造凝固过程中两种浇注方案的温度场进行模拟仿真,根据铸件温度场模拟结果分析,预测铸件凝固过程中的凝固顺序和可能产生缩孔缩松的铸件部位,最终选出了最佳浇注工艺方案。Taking vertical shock absorber seat as an example with sand casting technology, two sets of gating system schemes were designed, and the temperature field in solidification process of the two schemes were simulated and analyzed by the ANSYS software, respectively. According to the simulation result, the solidification sequence in solidification process and possible shrinkage porosity and cavity in the casting were predicted. Finally, a more feasible casting process scheme was obtained.
