Analysis on Draghead Teeth of Drag Suction Hopper Dredgers Based on the Theory of Fuzzy Reliability

Abstract:

Drag suction hopper dredger is dredg the hard compacted soil,dreghead teeth intensity will lead to an undersized cutting depth and a large cutting resistance, it raise failure probability. In this paper, investigate the relation between dredging depth，width,resistance and draghead teeth reliability influenced under different conditions,including various teeth,loads,navigating speeds and high-pressure jets.Discussed their effects on cutting depth,width and resistance.At last this paper obtain the reliability index and failure probability of the draghead teeth through the calculation numerical example.In this example,the method improvements efficiency for Draghead Teeth based on analysis on reliability.
