基于振动频率法的船舶系缆力试验研究
Experimental study of ship mooring force based on vibration frequency method
摘要
Abstract
The current method for measuring mooring force is unable to accurately and efficiently measure the force of a single ship cable.This paper presents an experimental study on measuring ship mooring force using the vibration frequency method,with reference to the calculation method of cable force measurement of cable-stayed cables.A prototype testing platform was built based on the current mooring environment.The study investigated the error rates of different data acquisition locations,excitation modes,excitation positions,and wet cables,taking into account the influencing factors that may cause theoretical errors and practical application requirements.The study proposed a new excitation mode based on environmental and manual excitation.Through an analysis of the vibration frequency method and tension values on the prototype test platform,it is concluded that the measured value of the ship mooring force is minimally impacted by the data acquisition position,excitation position,and excitation method.The error rate increases by approximately 1%in the presence of wet cables,resulting in a comprehensive error range of-5%to 4%.This error rate satisfies the normal distribution,and the measurement accuracy is corrected by correcting the length of the cable.It has been demonstrated that this method is highly feasible and applicable,and can effectively achieve simple,accurate,and efficient measurement of ship mooring force.关键词
