The Design And Experimental Study Of The Auxiliary System For The Amphibious Ship To Launch River By Itself

Work boats are usually used to complete the work of salvaging aquatic plants,garbage cleaning,water and land transportation,etc.,and has the advantage of one boat for multiple purposes.The process of transferring traditional work boats from the assembly workshop to the river is usually completed with the assistance of lifting equipment and airbags.In order to solve the problem of long time-consuming and low efficiency of traditional river transfer methods,this paper designs an auxiliary system for amphibious boats to launch to provide extra buoyancy for the hull so that it can travel smoothly from land into the water at a smaller inclination angle.This will greatly improve the efficiency of launching.The main research contents of this paper are as follows:(1)The amphibious ship is equipped with buoyancy airbags and the determination of the plan for retreating down the river: Through the analysis of the current research status of the way of amphibious equipment to launch at home and abroad,and combined with the actual working environment in the process of going down the river,the research plan is determined: the amphibious ship is equipped with buoyancy airbags and Take the way of going backwards down the river to go down the river.(2)The scheme design of the mechanical structure of the auxiliary system for amphibious boat going down the river: According to the demand of amphibious ships going down the river by themselves,clarifying the design requirements of the auxiliary system for going down the river,using Solid Works software to design its mechanical structure;analyzing the kinematics and dynamics characteristics of the mechanism through ADAMS software,Compare and determine the final plan;use ANSYS software to analyze and check the strength of key stressed parts;provide reference for the optimization of mechanisms and parts.(3)Design of the hydraulic system of the auxiliary system of ship launched: In order to make the auxiliary system of ship launched complete specific functions,the hydraulic system used to drive the mechanism movement is designed,the hydraulic pipeline diagram is drawn according to the working principle of the hydraulic system,and the hydraulic components are selected.(4)The design of control system of amphibious ship launched : the process of amphibious ship to launch needs to be completed by the crawler walking system and the auxiliary system of launching,which involves control terminal design,controller selection,sensor selection,electrical wiring,programming and programming.Debug and display instrument development.(5)Hydrodynamic simulation analysis based on the process of CFD amphibious ship going down the river: Simplify the amphibious ship model,use CFD software STAR-CCM+ to simulate and analyze its going down the river,record and analyze the changes of important parameters of the hull,and visualize the animation.The formal simulation of this process provides theoretical support for the river down test.(6)The commissioning of the auxiliary system for the river and the test of the amphibious ship: After the completion of the amphibious ship,the test will be carried out.The test consists of two aspects.On the one hand,it is the debugging of the auxiliary system of ship launched,which can be adjusted to achieve the desired effect through the control of the terminal;the other is the river-going test of the amphibious boat,which controls the crawler walking system and the auxiliary system of launching,The system completes the process of going down the river,verifying the feasibility of the amphibious ship equipped with buoyancy airbags and the retreat going down the river.
