The under-filling defect of I-beam in a heavy truck front axle which occurs in the process debugging of the precision roll-forging and die-forging is studied. Finite element models of precision roll-forging and die-forging are established based on FEM software and the previous productive results. Then, the mechanism of the under-filing defect in I-beam is studied. And the effects of the three variables including width B, radius R and slope A of I-beam in the third step on the forging quality are investigated. In addition, the roll-forging die constructions for I-beam in previous three steps are redesigned and manufactured. The productive results show that I-beam can be fully filled, the debugging cycle is reduced significantly and the products quality is guaranteed.  相似文献

The paper reviews the research status of the secondary clarifier model from one-dimensional model to three-dimensional model. The one-dimensional model based on solid flux theory was outlined by discussing how to choose model parameters such as settling velocity function and the number of layers. Based on the achievement of actived sludge model and the development of wastewater treatment technology, it is suggested that the development of the secondary clarifier model should focus on the establishment of some clarifier model including biological processes and the enrichment of hydraulics phenomena modeling.  相似文献
