AT THE SHIPYARDS
SHIP DESIGN
Boytsov G. V. New principles in standardization of ships' strength
The author gives proof to the necessity of revision of conventional standardization and provision of hull structures strength schemes on the basis of modern computer technologies.
Semyonova V. Yu. Calculation of nonlinear rolling of a ship positioned broadside to the regular sea
A procedure is proposed for calculation of nonlinear hydrodynamic forces that arise at ship's rolling and solution of rolling differential equations system taking these forces into account. Obtained results allow to make a conclusion about considerable influence of nonlinear factors.
Ter-Akopov A.M. General purpose cargo-passenger vessel
The author gives description and technical particulars of the lead general purpose cargo-passenger vessel intended for operation in river Hatanga and being built under project 2707 at PC "Krasnoyarsk Shipbuilding Wharf".
Ovsyannikov I.I., Shiskin A.D., Buyanov S.I., Nikolsky B.I. Multipurpose automobile-passenger-railway ferry for Baltic basin
The authors tell about new generation automobile-passenger-railway ferry ÏÌ-130/300 intended for operation in Baltic basin. Technical parameters are given for the project of this ferry and existing ferries of national and foreign build.
SHIPBOARD POWER PLANTS
Karagodina V. D. Particulars of automatization of main power plants of prospective surface ships
The author considers particulars of automatization of various types of main power plants with the use of microprocessor computer techniques.
Turkin V. A. Influence of design features upon safe shipboard auxiliary boilers operation
The author proposes procedures for strengthening of shipboard auxiliary boilers operation safety.
MARINE CONTROL SYSTEMS
Agunov A. V. Active voltage filtration in shipboard limited capacity electric power systems with nonlinear loading
The article describes an original method of active voltage filtration in shipboard limited capacity electric power systems with nonlinear and parametrical loading which permits to solve problems of supply mains' voltage quality improvement and provision of electromagnet compatibility in shipboard limited capacity electric power systems with nonlinear and parametrical loading.
Shamberov V. N. Investigation of dry friction influence upon accuracy and stability of shipboard automatic systems
A new approach to analytical investigation of stability and accuracy of multilinked automatic systems nonlinear dynamic models is shown. A mathematical model of a component with friction obtained with application of non-coulomb approximation of dry friction law for accounting of dry friction in controllers of these systems is proposed. Stability conditions are determined for systems with accepted dry friction model.
MARINE ELECTRICAL AND RADIO EQUIPMENT
Babiy V. I. Algorithmic method of increase of shipboard hydroacoustic speed of sound meters accuracy
The author proposes a simple mathematical model of hydroacoustic speed of sound meters that takes diffraction effect into account. The model allows to realize the potential possibilities of meters and to increase their accuracy with the use of algorithmic method.
INFORMATION TECHNOLOGIES
Rudoy K. V. Calculation of strength of port side sponson under influence of external pressure
The author proposes to calculate the strength of complex ship structure (sponson) by finite-element method with the use of software package Cosmos M. On the base of 3D model a design finite-element model of sponson structure was developed and structure components' mode of deformation was calculated. Results of calculations are presented in graphical form.
INDUSTRIAL ENGINEERING AND ECONOMICS
Isaev A. A., Polyakov Yu. I., Rudnev A. I. Justification of ship building cost
The authors consider the problems of determination of various types of ships building cost at different stages of their design basing on calculation method and particulars of price setting in conditions of modern market relations in Russian Federation. Description of indices used for calculations and software for determination of ship building cost is given.
