| 摘 要： | 利用有限元软件ANSYS/LS-DYNA,分别对4种具有不同表面形态(光滑、凹坑形、柔性与光滑耦合、柔性与凹坑耦合)的试件的耐冲蚀性能进行了三维数值模拟,计算出冲蚀磨损过程中等效应力的变化情况,并与试验结果进行了对比.结果表明,数值模拟的试件耐冲蚀顺序依次为:柔形与凹坑耦合>柔形与光滑耦合>凹坑形态>光滑形态,该结果与...

| Abstract: | The anti-erosion effects of different surface morphologies and their combinations were investigated by three dimensional finite element simulation using ANSYS/LS-DYNA. The surface morphologies include smooth surface, surface with concave units, flexibility and smoothness, and coupling flexibility and concave. The equivalent stress during the erosion process was calculated. Results show that the calculated equivalent stress matches the actually measured wear loss very well. It is shown that appropriate selec... |
