Maneuvering motion sensitivity analysis of submersible underwater towed system
In order to study the influence of various parameters of underwater submersible towed system on the man-euvering motion response,the cable dynamics numerical simulation method is used to analyze the motion response sensitiv-ity of the towed system.Based on the dynamic equation of the towed cable established by the lumped mass method,the vari-ation of the towed depth and the tension of the towed cable are taken as the analysis indexes.The maneuvering motion of the towed system is variable speed linear motion and uniform rotation,and the sensitivity index of each parameter of the system is calculated.The influence of parameter changes on the maneuvering motion of underwater submersible towed system is analyzed from the two aspects of towing manipulation parameters and structural parameters.The importance of the influence of different parameters on the motion response of the towed system is determined by sensitivity analysis.It is helpful to ad-just the motion state of the towing system quickly and correctly in engineering application,and provides theoretical support for designing underwater submersible towed system and simplifying the maneuvering motion equation of the system.
