Vibration characteristic of marine towing rope type anti-swing device
In order to reduce the vibration generated when the ship was operating with a towing rope to improve the stability and safety of the system,a vibration model of the towing rope was established by combining the catenary theory and the chord vibration principle,Adams was used to simulate the vi-bration situation of the towing rope in actual work,and then the simulation analysis was carried out by using Matlab.Re-sults show that the hysteresis of the hydraulic system can re-suit the vibration of towing rope.When the response time of the hydraulic system decreases from 1 s to 0.1 s,the ampli-tude of the towing rope decreases by 90％.The unit mass,length,and whether dampers on the traction cable can all have an impact on vibration,and installing dampers can re-duce the amplitude of the towing rope by 97％within 4 s.The results have certain guiding significance for the practical ap-plication of towing rope type of anti-swing device.
