Research On Hydraulic Brake Based On Positioning Car Of Shenhua Huanghua Port

Car dumper system is the cargo handling vehicle machinery, widely application inports, steel mills and the in power plant. The positioning of the car dumper system and thebrakes on car cart movement is frequent, requirements high reliability. So this topicAccording to electromagnetic circuit board brake can’t be used normally in the car dumpersystem and in car equipment. Design a kind of to hydraulic for the engine brake. This kindof brake structure is simple and easy to operate, reliable working, cost low.This paper first introduced the dumper system composition, basic structure andworking process in detail. On this basis, analysis the cart machine and electromagneticbraking system positioning car present situation also the problems of fault occurred. Inorder to overcome the circuit board of electromagnetic brake by the influence of theharmonic voltage and serious, adopt hydraulic centralized control instead of the originalelectromagnet control. According to the specific conditions of hydraulic designrequirement for system, specific design and calculat the hydraulic cylinder of parameters,also select hydraulic components are needed.This paper by means of finite element software ANSYSWorkbench such as staticanalysis and optimization design module, static analysis the hydraulic cylinder cylinderand optimize the inner cylinder thick. In the conditions of satisfy the cylinder stress anddeformation, reduce the quality of the cylinder, especially coMPared the traditional designmethod, design method of based on ANSYSWorkbench improving material utilizationratio, reduce the production cost, for r design and optimization hydraulic cylinde providean effective and feasible way.Use AMESim simulation software, in the two cases of the feedback signals weresystem pressure and the piston rod displacement simulation analysis the system. Throughthe analysis we concluded that pressure feedback signal system is smaller deviationcoMPared with theoretical derivation, but the displacement feedback of the hydraulicsystem with some lag, Finally according to the simulation results find out the way toimprove the system. With hydraulic brake hydraulic system as an example, analyzes thehydraulic system pollution source, then According to different sources puts forward several method to prevent and control pollution. For brake system are better applied towork, improve the system performance,and prolonging the life of system put sometheoretical basis.
