摘要
对起重机建立准确的数学模型是研究其防摇摆控制策略的基础.构建在偶然载荷作用下桥式起重机摇摆数学模型,分析桥式起重机一个作业循环以及大小车运行时的受力情况,在充分考虑偶然载荷作用下构建桥式起重机工作过程中的三维动力学数学模型.通过在驱动力及风载作用下对模型的仿真分析,研究桥式起重机的摆角变化规律.桥式起重机在偶然载荷作用下的摆角模型及其变化规律可为后续桥式起重机的防摇摆控制提供理论基础,保证桥式起重机在偶然性载荷作用下工作安全可靠.
Abstract
Establishment of an accurate mathematical crane model is the basis for study of its anti-sway control strategy.This paper constructs a mathematical model for the sway of an overhead crane under accidental loads,analyzes the stress situation of the bridge crane during a working cycle and the operation of large and small vehicles,and builds a three-dimensional dynamic mathematical model during the operation of the bridge crane under the full consideration of accidental loads.The simulation analysis of the model under the action of driving force and wind load is conducted,and the change law of the swing angle of the bridge crane is studied.The swing angle model of bridge crane under accidental load and its variation law provide a theoretical basis for the anti-sway control of subsequent bridge cranes and guarantee the safety and reliability of the bridge cranes underthe action of accidental loads.
