Статья посвящена вопросам проектирования корпусов судов из полимерных композиционных материалов. В качестве объекта исследования рассматривается прототип судна-катамарана. Целью работы является модификация композитного корпуса прототипа, предполагающая замену армирующего элемента в композиционном материале с углеродных волокон на стеклянные в целях снижения стоимости конструкции. Основными задачами работы являются разработка модифицированной структуры элементов конструкции корпуса на основе анализа прочности, а также анализ экономической эффективности выполненной модификации. Анализ прочности композитных конструкций корпуса выполняется с помощью прямого конечно-элементного (КЭ) моделирования с применением системы КЭ анализа ANSYS Mechanical APDL. Расчётная методика основана на требованиях классификационных сообществ DNV GL и Российского морского регистра судоходства (РМРС). В результате работы на основе многовариантного конечно-элементного анализа выполнена модификация существующего проекта судна под материал с существенно отличающимися прочностными и жесткостными характеристиками при минимальном изменении геометрии корпусных элементов. Обоснована возможность уменьшения затрат на материал корпуса в 1.5-2- раза при незначительном увеличении водоизмещения и с условием обеспечения прочности корпуса в соответствии с требованиями международных и российских классификационных сообществ. The article is devoted to the issues of designing ship hulls from polymer composite materials. A prototype of a catamaran ship is considered as an object of research. The aim of the work is to modify the composite body of the prototype, which involves replacing the strengthening element in the composite material from carbon fibers to glass ones in order to reduce the cost of the structure. The main tasks of the work are the development of a modified structure of the hull structural elements based on the strength analysis, as well as the analysis of the economic efficiency of the modification. Strength analysis of composite hull structures is performed using direct finite element (FE) modeling using the ANSYS Mechanical APDL FE analysis system. The calculation method is based on the requirements of the classification associations (DNV GL) and the Russian Maritime Register of Shipping (RMRS). As a result of the work, on the basis of multivariate finite element analysis, the existing ship design has been modified for material with significantly different strength and stiffness characteristics with minimal changes in the geometry of the hull members. The possibility of reducing the cost of the hull material by 1.5-2 times with a slight increase in displacement and with the condition of ensuring the strength of the hull in accordance with the requirements of international and Russian classification associations has been substantiated.

The wheel of a vehicle plays a vital role to bear the load applies on it. Generally spokes acts as the supports between the wheel rim and hub. These spokes must have sufficient strength and stiffness to avoid the failure of the wheel. In present days these wheels are made up of aluminum alloy, magnesium alloy and steel. To reduce the weight of the wheel many wheel designs are implemented and applied for different vehicles. In this paper three different wheel designs are chosen, those are inclined spokes, curved spokes and Y shaped spokes made up of Al alloy, Mg alloy and Steel. Static structural analysis subjected to pressure on the wheel rim and free vibrational analyses are performed by using finite element analysis tool Ansys 12. The objective of the present work is to observe the best design which contains higher structural stiffness, specific structural stiffness with lower von mises stresses under static load conditions. It is observed that curve shaped spoke designs are better in for manufacturing of wheel in both static and dynamic point of view.

This paper introduces a optimize design method of ship unloader. The traditional structure design method is totally by experience and manual calculation, while this method is using the Finite Element Analysis (FEA) method to optimize the structure of ship unloader. Therefore this method may keep the stress and deformation of the structure under permission with less use of materials. First we use the FEA analysis software ANSYS to analyze the static strength and stiffness of grab ship unloader, and get its stress and deformation under different work conditions. Then we evaluate the results and modify the structures to improve the performances of the structure under the complex working conditions. Case study shows this method is effective and efficient in practical use.

Abstract The paper is devoted to the strength analysis of a simply supported three layer beam. The sandwich beam consists of: two metal facings, the metal foam core and two binding layers between the faces and the core. In consequence, the beam is a five layer beam. The main goal of the study is to elaborate a mathematical model of this beam, analytical description and a solution of the three-point bending problem. The beam is subjected to a transverse load. The nonlinear hypothesis of the deformation of the cross section of the beam is formulated. Based on the principle of the stationary potential energy the system of four equations of equilibrium is derived. Then deflections and stresses are determined. The influence of the binding layers is considered. The results of the solutions of the bending problem analysis are shown in the tables and figures. The analytical model is verified numerically using the finite element analysis, as well as experimentally.

As lifting points for ship block turning over and hoisting operation, the strength of the lifting eye directly affects the safety of the operation, therefore it is required for extreme high reliability. The conventional strength analysis can not exactly describe the actual stress and working conditions of the lifting eye, nonlinear contact and simplified finite element arithmetic are used for analyzing and checking the lifting eye's strength in this paper; and the stress force distribution formula, which can well reflect the true status of the pressure-bearing surface, is researched. Through the comparison of the various calculation methods, it can be found that the reasonable simplified method can approach the nonlinear contact finite element arithmetic with high precision and is characterized with higher calculation speed and more concise and practicable.
