The invention discloses a tower crane stable operation coupling system, and relates to the technical field of tower cranes. Comprising a swinging and hoisting swinging rule research module, an anti-swinging control strategy analysis and research module, a rigid simple pendulum module, a variable amplitude motion dynamics model unit, a super-lifting motion dynamics model unit, a rotary motion dynamics model unit, a composite motion dynamics model unit, a rigid-flexible coupling module and a three-dimensional space multi-degree-of-freedom dynamics model. According to the tower crane stable operation coupling system, the flexible multi-body dynamics theory is applied to engineering practical problems, the coupling effect of structure elastic parallel and rotary motion and suspension moving load is considered, and an accurate multi-flexible-body deformation-motion coupling dynamics model comprising a whole tower body and a hoisting system is established; the shimmy characteristic of the hoist is researched on the basis of establishing the tower crane-hoist complete system model, so that the shimmy research result of the hoist is more accurate.
