The composition and damping mechanism of mechanical anti-rolling device manufactured by a port machine company are analyzed. The corresponding dynamic model is established. The swing curve of the balance beam and lifting weight is obtained by the numerical method. Numerical calculation and test results show that the device has a better pendulum effect. Moreover, the theory presented in this paper provides the basis for the design of this type of anti-rolling mechanism, which has great application value
