摘　　要：针对绞吸挖泥船在疏浚工程中刀齿磨损严重的问题,对绞刀齿的硬质合金材料进行热处理,并在日照港"天凤"绞吸挖泥船上进行了刀齿磨损试验。试验土质为黏土混粗砂,布置方式为3在用刀齿+3新刀齿。利用磨损长度和磨损质量两个指标判定刀齿的耐磨性能,提出了考虑价格因素的刀齿耐磨综合性价比模型。试验结果表明:在该土质下,新型刀齿的耐磨性能约为原齿的87%。In view of the severe wear of the cutter teeth in the dredging project of the cutter suction dredger,the carbide material of reamer teeth is heat-treated,and the test of cutter teeth wear is carried out on the"Tianfeng"cutter suction dredger in Rizhao Port.The test soil is clay mixed with coarse sand,and the arrangement is 3 active cutter teeth and 3 new cutter teeth.Two indicators,the wear length and wear weight are used to determine the wear resistance of the cutter teeth,and a comprehensive cost-performance model for the wear resistance of the cutter teeth considering price factors is proposed.The test results show that the wear resistance of the new cutter teeth is about 87%of that of the original teeth under this soil.
