Abstract：This study investigates the dynamic force transmission in cable-pulley systems under impact loading. A dynamic model is developed that incorporates cable axial vibration, nonlinear friction, pulley damping, and energy distribution. Using an integrated approach of theoretical analysis, finite element simulation, and experimental validation, the research elucidates the effects of pulley wrap angle and damping on tension transmission during impact. The results indicate that pulley damping is a key parameter governing the system's impact tension response—increased damping significantly reduces transmission efficiency. Meanwhile, a larger wrap angle enhances energy dissipation by extending the contact arc, leading to a slight decrease in transmission efficiency. The proposed modified friction model offers improved accuracy in predicting tension response under impact conditions, providing a theoretical basis for the safety design of engineering equipment equipped with cable-pulley mechanisms.
