Abstract

The invention discloses a seabed surface sediment vehicle ground mechanical property dynamic testing device. A soil tank is fixed to a rack and contains simulation sediment, and a creeper tread testing mechanism is fixed to a bottom plate. By means of the device, normal loading and testing of normal loads and normal indenting displacement can be achieved, pushing of a traveling mechanism is simulated, corresponding shearing displacement is tested, and a stepping motor drives rollers to drive a guide rod connected with a steel wire rope so that the mechanism can be driven to replace a testing position and a track. By means of the device, the traveling work process of the crawler-type operating vehicle traveling mechanism on seabed surface sediment is achieved under laboratory conditions, mechanical property dynamic change process data of measuring pressure and settlement, shearing stress and shearing displacement and the shearing and bearing coupling function are simulated, and a simulation testing platform and detailed testing data are provided for seabed mining vehicle structural design optimization and traveling and passing performance assessment analysis.

Description

technical field [0001] The invention relates to a dynamic testing device for the mechanical properties of vehicles on the surface of the seabed. Background technique [0002] The deep seabed contains extremely rich mineral resources. The seabed mining operation vehicle is the most cutting-edge and most critical equipment in the deep sea mineral resource development system. Its seabed walking performance directly determines the continuous operation performance of the entire deep sea mining system. The ground mechanical properties of vehicles in seabed sediments is the most important premise and basis for designing, optimizing and evaluating the running performance of seabed mining vehicles. The work vehicle cannot be tested effectively, which affects the use. Contents of the invention [0003] The technical problem solved by the present invention is to provide a dynamic testing device for the ground mechanical properties of the submarine sediment vehicle, so as to solve th...
