Abstract

The invention belongs to the technical field of dredging engineering, and relates to a device and method for simulating draghead tooth operation and carrying out parameter analysis and force measurement. The device comprises a draghead function module, a draghead tooth cutting module and a force measurement adjusting module; the draghead function module is used for providing the cutting force of draghead teeth and adjusting the cutting posture of the draghead teeth; the draghead tooth cutting module is used for adjusting the cutting angle of the draghead teeth and changing tooth types, and isused for realizing connection of the draghead teeth and the force measurement adjusting module, and when the draghead teeth are used for cutting a soil layer, a draghead tooth load is transferred to the force measurement adjusting module; and the force measuring adjusting module is used for adjusting load measuring force and the draghead tooth distance during the digging process. According to thedevice and method, actual operation draghead teeth can be carried, position and posture changes of the draghead teeth on the cut soil layer are realized, all the operation ranges of the draghead teethare included, cutting parameters can be adjusted, and the cutting parameters are kept stable and unchanged in the cutting process of the draghead teeth, and a six-axis load borne by the draghead teeth can further be measured.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering, and relates to a device and method for simulating the rake tooth operation of a rake suction ship and performing parameter analysis and force measurement. Background technique [0002] With the development of economy and social life, human beings have an increasing demand for the exploration and utilization of the ocean and marine resources. These demands have prompted the rapid development of dredging engineering and various fields of marine engineering. One of the typical methods of seabed material construction. The typical equipment is a trailing suction dredger. The rake head is the working part of the dredging dredger to excavate the soil layer. The function of the rake head is to excavate underwater sediment and other substances, and Make it mixed with the water entering the rake head to form a slurry, and then transport it to the predetermined position by means of fluid transp...
