Anti-sway System Research On The Brachial-Bridge Portal Container Crane

Brachial-bridge portal container crane,based on Luffing crane changing its portal system,is a new container shore crane,with the characteristic of loading and unloading high efficiency and the scope of work of advantages.During the development process of Brachial-bridge portal container crane,in addition to its optimized Luffing system design,operation of the sports car the process of calculation and simulation,optimizing the design of metal structures,how to reduce and prevent the container when the luffing mechanism swing brake,is a prominent issue of research and development Brachial-bridge portal container crane,luffing crane in the course of the container as a result of inertia resulting from a direct impact on the issue of goods rock affected the efficiency of loading and unloading cranes. Brachial-bridge portal container crane the trolley movement of compared to common shore container cranes are very different.It is essential to analysis and design brachial-bridge portal container crane anti-sway system.In this paper,according to the design features of brachial-bridge portal container crane,as well as the container bridge crane boom luffing system operation rules,to analyse the operation law of the trolley,to determine the possible corresponding of brachial-bridge portal container crane anti-sway system based on electronic and mechanical anti-sway mechanism.Modeling and calculation of kinetic analysis on the trolley Cargo system taken anti-sway measures.Research in MATLAB environment on semi-physical simulation,At last it is necessary through ADAMS software to further verify the theoretical analysis the latest kind of anti-sway system performance.1) By controlling the speed of cars to a certain extent,to reduce the hoist swing, but the results are unsatisfactory,and working efficiency is reduced;2 An energy-based anti-sway damping method to increase the focus on me automatic spreader relative motion of the pulley to increase the system damping, thereby reducing the swing spreader system to reduce the decay time.3) Against the new anti-sway device,the use of Lagrange equation hoist trolley system dynamics model.And the use of MATLAB software simulation of the actual system,determine the anti-rolling movement in the process of attenuation of the effect of laws and swing.4) Based on ADAMS through the description and simulation of hoist trolley system,to further verify the anti-sway measures' feasibility and effectiveness.
