摘　　要：研制了一种模拟疏浚工况的泥沙磨损试验机,通过试验确定该试验机最佳工况,试验机能够模拟挖泥船泥泵过流部件的磨损,快速获得磨损试验结果。在选定的试验工况下试验机的磨损试验数据稳定性较好,重复性误差小,重现性误差小,能够用来评定疏浚工况下材料的耐磨性。The standing sand slurry wear tester simulating the dredging condition was developed according to practical condition. The optimal standard of the test machine was determined by experiments. The wear of the dredging device overflow components can be simulated by the standing sand slurry wear test apparatus and the results of the wear test can be obtained quickly. Under the determined standard, the test machine has a good stability with little repeating error and recurring error, so it can be used to evaluate wearability of the materials under dredging condition.
