铸造CAE应力仿真技术在轮毂裂纹预测中的应用

Application of CAE Stress Simulation Technology in Crack Prediction ofSteel Wheel Casting

为彻底解决某型履带式车辆轮毂铸钢件裂纹缺陷,实践运用了问题定位“排除法”,科学判断出轮毂铸钢件裂纹发生的根本性问题,进一步运用ProCAST铸造应力模拟仿真技术,对轮毂铸钢件结构进行应力模拟分析。结果表明,模拟分析可预测出轮毂铸钢件裂纹缺陷的主要分布部位,通过对轮毂铸钢件优化工艺方案及相关试验验证,彻底解决了轮毂铸钢件的裂纹问题,保证了批量生产的顺利进行。

In order to completely solve the crack defects of a tracked vehicle wheel casting,the problem location“elimination method”was applied in practice to scientifically judge the fundamental problem of wheel casting crack,Furthermore,the stress simulation analysis of wheel casting structure was carried out by using ProCAST casting stress simulation technology,The results show that the main distribution locations of crack defects in hub steel castings are predicted,and the crack problem of hub steel castings is completely solved by optimizing the technological scheme of hub steel castings and relevant test verification,and the smooth progress of mass production is ensured,
