摘要：The research on digging resistances is the key to designing the grab, improving the grab’s structure and realizing the automatic flat digging of grab dredger. This article focuses on the mechanical analysis and experimental research of grab’s flat digging combining with theoretical calculation and experiments in dredging process. The theoretical digging resistances in both horizontal and vertical directions have been investigated in mathematical model. With the help of flat digging experiments, the forces on hoist rope and closing rope have been recorded. Then, work out the horizontal and vertical digging resistances based on moment balance. Since a good agreement is achieved between the theoretical calculations with the corresponding independent experimental results, the research has been verified and provides technical support for flat digging in dredging process.
