effective depth of regular wave on submerged submarines and auvs
International Conference on Robotics and Automation, 2017Co-Authors: Mohammad Moonesun, Firouz Ghasemzadeh, Yuri Mikhailovich Korol, Nikrasov Valeri, Alexi Yastreba, Er UrsalovAbstract:This paper evaluates the effective depth of waves on the submarine at the depth of water At the depth called the quot Wave Base quot which equals to l the wave effects become so small that motions are negligible This paper aimed to recommend a minimum safe depth for calm and stable motions of a submarine This paper concludes the depth of lcould be recommended as an operational safe and approximately calm depth for submarines For this study a torpedo shaped submersible is analyzed in some depths accompanying by regular surface wave By increasing the depth the reduction of submarine motions is evaluated The results of this research can be used for AUVs research Submersibles and naval submarines This analysis is performed by CFD tools of Flow D V software based on solving the RANS equations and VOF method

i auv mechatronics integration for the trident fp7 project
IEEE-ASME Transactions on Mechatronics, 2015Co-Authors: David Ribas, Pere Ridao, Alessio Turetta, Claudio Melchiorri, Gianluca Palli, J J Fernandez, Pedro J SanzAbstract:Autonomous underwater vehicles (AUVs) are routinely used to survey areas of interest in seas and oceans all over the world. However, those operations requiring intervention capabilities are still reserved to manned Submersibles or remotely operated vehicles (ROVs). In the recent years, few research projects have demonstrated the viability of a new type of submersible, the intervention AUV (I-AUV), which can perform underwater missions involving manipulations in a completely autonomous way. The EU FP7 TRIDENT project is one of the most recent examples of such technological concept. This paper describes the different mechatronic components that constitute the I-AUV developed for the TRIDENT project, their hardware and software integration, and the performance of the vehicle during the project trials.

starting performances of delta modulated inverter fed submersible induction motors
IEEE Transactions on Industry Applications, 1992Co-Authors: M A Choudhury, M A RahmanAbstract:An analysis of the starting performance of tuned delta-modulated inverter-fed submersible motors is presented. Submersible motors are induction motors having unique constructional features. These motors are required to operate in one of the harshest environmental conditions. The operating characteristics of a submersible motor pump system require a soft starting facility and variable speed operation. To satisfy both requirements, a delta-modulated inverter supply is proposed, and its starting performance is presented. The soft starting characteristic of the motor was obtained by the inherent V/f, control of the delta-modulated inverter. The analysis was carried out using time domain representation of inverter voltages and the d-q axis model of the motor. The time domain representation of inverter voltages was done using gate functions. The starting performances of the submersible motor improved substantially. Although the analysis and results presented are for a submersible model, these are equally applicable for any type of polyphase induction motor. >
