According to the force state of the object,the dynamic equations of bridge crane in the hoisting process were built,and the kinetic e-quations of the object were also got,the passive control laws of bridge crane were also presented,so as to lay the foundation for researching the in-telligent control technique of tower crane hoisting.%根据被吊物体的受力,建立了塔吊吊装过程的动力学方程,并推出了被吊装物体的运动方程,以及塔吊的控制规律,为进一步研究塔吊吊装智能控制技术奠定了基础。
