Modeling and simulation of the mechanical & hydraulic coupling of the hoisting system of bridge cranes
摘要
Abstract
With the consideration that the hoisting system ' s mechanical part as the actuator is driven and controlled by the system's hydraulic part, and the dynamics problem of the mechanical part can be solved by the system 's hy-draulic part, to effectively improve the stability of the actuator of bridge cranes ' hydraulic hoisting system , the strong mechanical-hydraulic coupling relationship in the hoisting system is studied .The mathematical model and simulation model for the mechanical-hydraulic coupling in the hoisting system are established .Then, through simu-lation, the action of mechanical-hydraulic coupling on the hoisting system ' s performance is analyzed , and the cou-pling parameters of the secondary lifting and sliding problem are determined through the simulation analysis of me -chanical-hydraulic coupling of the hoisting system .Finally, the fitting function is established by coupling parame-tersinoil elastic modulus , motor volumetric efficiency , load weight and glide displacement .Combined with the opti-mization algorithm , the optimal solution of the secondary lifting and sliding problem is obtained .关键词
