基于二维切削理论的绞吸式挖泥船绞刀头载荷分析

Cutting Force Calculation of the Cutter Suction Dredger Based on 2-D Soil-cutting theory

为计算绞吸式挖泥船绞刀头在不同工作状态下所受到的载荷作用,引入二维切削理论,根据不同的土质特征以及绞刀的不同几何形状和工作状态,对绞刀头所受到的载荷进行分析和研究。根据各参数之间的关系,用FORTRAN语言来实现载荷的计算,并对最终结果进行可靠性分析。

The two-dimensional soil-cutting theory was applied to analyze the loadings on the cutter head under different circumstance. The loadings on the cutter head were studied for different soil, different shapes of cutter and different, working conditions. According to the relationship of various parameters, a FORTRAN program was used to calculate and analyze the cutting force.
