| With the development of ocean resource exploration,the state play more attention to the marine environmental detection technology than before.In recent years,as an environment monitoring equipment bottom mount has been widely used in the marine environment monitoring.However,the low recovery rate of bottom mount is an important reason to restrict its development.The adsorption force is the main factor affecting the recovery of bottom mount.A lot of experiments have been done to obtain the empirical formula of the adsorption force of the mechanism,but it has been the focus of scholars to accurately analyze the influence of the structural factors on the adsorption force.With the continuous improvement and development of finite element technology,computer simulation technology has been widely used because of its high cost performance,easy operation and other advantages.Firstly,use the Solidworks to simplify the modeling of bottom mount.And then,use the ABAQUS to simulation the bottom mount adsorption force on various influence factors.According to the simulation result to guide the bottom mount design.Through the study found that the depth and elevation are the main factors to affect the adsorption capacity of bottom mount;The adsorption force decreases with the increase of the number of holes in the bottom moun,but the effect is lower than the depth and the elevation;The influence of the shape of the base on the adsorption force can be ignored,and the design can be selected according to the needs of the equipment;through the analysis of the consolidation time can be seen,consolidation time is short,seabed base bottom about 10 days after the mud hole pressure has been lifted.From the seabed base at the bottom of the work that need not consider the influence of pore pressure dissipation of non silt seabed based adsorption force;the factors the seabed based adsorption effect,optimize the design of the overall framework of seabed base cover,form and structure of the instrument module. |
