Dynamic Response of Multi Branched Towed-array under Ship Track of Petal Pattern
The towed array plays an important role in the process of marine resources exploration and militaryinterception.For some special tasks,the ship needs to make a special navigation trajectory,such as direct sailing,turning maneuvers and so on.In this paper,Based on the parameters of a multi-branch system and its working process in the petal trajectory,the towed cable is discretized into lumped mass model,and the dynamic analysismodel of the multi-branch towed array under ship track of the petal pattern is established.The change of tension along the length direction and the tension of the trailing end of the towed cable are obtained by using the time-domain coupling analysis,which is helpful for the concrete engineering practice.
