Abstract

The invention discloses an underwater track equipment flow field and mechanical response prediction method and system, and the method comprises the steps of building three-dimensional solid models oftrack equipment with different attitudes and underwater environments with different terrains in batch, combining and assembling the three-dimensional solid models in a crossed manner, and obtaining anassembly model; carrying out fluid mechanics and structural mechanics analysis on the assembly model, and establishing water environment models of different terrains and track equipment finite element models of different postures; obtaining flow field data and structural body mechanical response data of the crawler equipment with different attitudes at different flow rates; and establishing a corresponding relationship between the flow field data and the structural body mechanical response data of the crawler equipment with different attitudes at different flow velocities so as to predict theflow field and dynamic response of the crawler equipment with different attitudes under the water. According to the scheme, the calculation precision can be guaranteed, and meanwhile, the predictionspeed of different attitude dynamic responses and flow fields of the underwater crawler equipment is increased.

Description

technical field [0001] The invention relates to the technical field of model prediction methods, in particular to a method and system for predicting flow field and mechanical response of underwater crawler equipment. Background technique [0002] In recent years, urban waterlogging and mine floods have occurred frequently, causing serious casualties and economic losses. Urban waterlogging has become one of the main problems in the process of urbanization. [0003] Emergency rescue is a lesson learned after a tragic accident, and emergency rescue equipment is a powerful weapon and an important guarantee for emergency rescue, and plays an extremely important role. The operating environment of urban waterlogging and river dredging is complex and has many risk factors. It is necessary to rely on strong wading, multi-functional, and high-mobility crawler equipment with remote control capabilities to coordinate ground and underwater emergency rescue operations. [0004] However,...
