Crane is an important component of engineering machinery, which widely applied in the urban construction, water conservancy, mines and defense engineering fields. However, when it refers to the hoisting system design optimization, still often rely on experience and the prototype test method, there is not only has the weakness of long design cycle, also we have to face the problems such as accurate design and wasting property.Crane hydraulic system in the design process should not only consider the static characteristics, but also to take into account whether the dynamic characteristics meet the requirements. As a result, its system simulation analysis is very necessary, simulation analysis can understand that all models of hydraulic components and parameters on the system dynamic response of the impact of hydraulic components by changing the parameters of the model and to change the dynamic response of. On this basis, the establishment of a digitized Dynamic Virtual Prototyping, select an appropriate optimization method to amend various size parameters, in order to achieve its overall optimal dynamic characteristics. Based on the above, we studied on the crane hoisting system which based on AMESim software to analysis and optimization simulation design. So that guarantee the safety, stability test, the shorter period, and improve economic efficiency.The core purpose of this paper has raised that when we finish the completion of the design, we should use computer to do the simulation of system firstly. Form a preliminary understanding of various hydraulic system characteristics, and optimize the design of unreasonable, reduce the blindness of design.Above all:First of all, this paper discussed the second lifting phenomenon of the crane and introduced the basic way to solve it. Second, I introduced the composition of the crane hoisting mechanism, and introduced the typical pattern of the crane hoisting mechanism. After analyzing some common principle hydraulic hoisting system, the paper proposed the principle of the hydraulic system and did some calculation on matching hoisting Circuit technical parameters. After that, the dynamic model of the hydraulic crane and the circuit of the crane hoisting mechanism were established, the dynamic nature was analyzed. Then several ways on the hydraulic system simulation modeling were introduced. On the control system of study, the establishment of the mathematical model is very important, it is essential for strong tool to design systems, analysis of system performance and improve the structure. In this paper, AMESim software as the basis, establish a simulation model of the hydraulic system or and simulation analysis of the hydraulic system, analyzed the impact of the dynamic characteristics of the main factors. On the basis of above, optimize the important part of hoisting system of balancing valve. And verify the feasibility of the simulation model of optimization.
