摘　　要：依据流体静力学理论,确定实验室模拟淹没水射流的方法及装置,利用此装置模拟水深对淹没磨料射流的冲蚀性能的影响进行了研究.实验结果表明,在相同的工况下,达到一定的模拟水深后,淹没磨料射流的冲蚀性能呈下降趋势.The development and application of simulated water depth are introduced. On the basis of hydrostatics, a set of experimental propositions and equipments of submerged abrasive waterjet (AWJ) is adopted to conduct an investigation on the relationship between eroding depth and simulated water depth in lab. The primary analysis shows that eroding capability of submerged AWJ drops when the depth is larger than the best. The study could provide some theoretical reference for further studies in this field.
