The Rig Design And Strength Analysis Of The Test Bed For Ocean Winch

In the deep sea exploration operations, the need to put a winch hanging weighing 20 tons of deep-sea exploration equipment, winch mounted on the research ship’s deck and winch dipping process with wave oscillation. In order to squeeze the strap winch not have a big impact load, retractable winch automatically adjusts the speed required to compensate for the ship’s heave motion. Designed that based on the counterweight tower and hydraulically driven winch combined test bed. That achieved the test of deep sea exploration dipping winch carrying capacity, active heave compensation capabilities, braking capacity and the carrying capacity of the pulleys and cables. And test-bed tower structural strength analysis. The main research is as follows:Load determined. Determined the load of test load and drum brake. Analyzed the max impact load of counterweight in the experimental process.Designed of test rig tower. Based counterweight the experimental process maximum impact load, designed the tower body size. Focusing on the analysis of the experimental process counterweight maximum impact load, designed the tower body size. Completed the design and selection of parts and components of the tower.Designed of hydraulic systems. Introduced the working principle of the hydraulic system, and completed the selection of hydraulic components.Test rig tower finite element model. Because of the complex structure of the tower. If the direct solid modeling that meshing difficulties. Modeling using ANSYS command stream, bottom-up generation point, line, surface, the used of beam, shell element to establish a finite element model of the test station tower.Test-bed tower structural strength analysis. Calculated loaded load of the tower that based the greatest impact of the counterweight. Analyzed the constraint status of the tower. Ansys finite element software tower structure was static analysised and modal analysised: static analysis based on results of the calculation results, the test-bed tower components optimized; tower vibration period to avoid the winch the maximum working load frequency.Beam strength analysis of the tower base. Based on ANSYS finite element software to establish a finite element model of the base beam, the static load analysis based on the maximum impact load weight, draw the base beams in the two conditions of stress and strain data to verify the safety of the base beam, and on the base beam structure has been optimized.
