Research On Optimization Of Lifting And Swinging Prevention Of Large Lifting Equipment

As a connecting point of international logistics,the port is a special venue integrating container transport,import and export logistics.Its transport system is a manifestation of the comprehensive national strength of the country.The most common equipment in these port operations is the lifting equipment.Large lifting equipment(that is lifting)refers to the crane or lifting gear for the installation of goods,in place of the general term.As a handling tool,it has been widely applied to the handling of various types of industrialized enterprises in the country by size.Since the lifting speed can not always be consistent with the running speed of the trolley during the lifting process,the lifting yaw angle will be generated during the lifting process,and the lifting equipment brought thereby can not be punctual and accurate for loading and unloading at the target position,not only failed to meet the modern enterprise’s high efficiency requirements for cargo handling,but also may lead to accidents.Therefore,research on the optimization of hoisting and swinging of large-scale hoisting equipment has certain far-reaching significance for improving the hoisting working efficiency.This article mainly studies on the lifting system of large lifting equipment,the main contents including:In order to accurately describe the law of motion of hoisting yaw,the Lagrange equation was first used to establish the hoisting system of cart and trolley composite motion of the three-dimensional dynamic model,through the analysis of the dynamic model shows that composite swing angle can be generated by the horizontal angle and the vertical direction of the angle,while the two directions of the angle is irrelevant,so for the purpose of targeted study,the three-dimensional model is simplified,and its two-dimensional dynamic model is established only when the car is moving horizontally.Then by analyzing the relationship between the parameters in the model,the optimal path of lifting system can be further solved.In order to solve this constrained nonlinear optimization problem,through the understanding of this kind of problem solving method evolutionary algorithm and the study of interior point method of initial population method,the joint differential evolution and multi-objective optimization of initial population selection based on interior point method algorithm for solving the single objective nonlinear constrained optimization problem.The entire lifting system is divided into static unloading and swing unloading two unloading ways for trajectory analysis and optimization,and then the optimization algorithm is used to solve the problem,and the optimization results are simulated and analyzed.Finally,the algorithm has certain validity and practicability in solving such problems.Using C#programming language in Visual Studio 2010 to design and build a simulation platform for lifting system operation.the Lord to introduce its login screen,the main interface,the parameter interface and the basic parameters of the operating parameters interface,and then use a practical example of the entire lifting system to demonstrate the dynamic process.
