A conformal design method of warship equipment and structure

Abstract

The invention relates to a conformal design method of warship equipment and structure, including: 1, determining the elements of platform equipment, including the positioning position of the equipment, the arrangement direction and the connection form of the equipment and the platform. 2, calculating that pressure Pc calculated by the platform; 3, carrying out grid strength checking on that platform structure: supposing sigma 2c is the equivalent stress along the short side direction of the plate center, sigma s is the yield strength of the material, calculating the value of sigma 2c, judgingthe magnitude relation between | sigma 2c | and 1.25 sigma s, and if | sigma 2c | (1.25 sigma s), the grid meets the strength requirement; If | sigma _ 2c | >= 1. 25 sigma _ s, the equivalent stress sigma _ 2c is calculated by adjusting the thickness and weight of the plate until | sigma _ 2c | (1.25 sigma _ s. As the conformal design method, not only can the large space occupied by the platform and equipment in the design process be effectively improved, the construction difficulty and the design rework caused by the interference can also meet the requirements of strength and stiffness, as well as a balanced and optimal design scheme with lighter structure weight and larger layout space under the conditions of not affecting the installation, use and maintenance of the equipments.

Description

technical field [0001] The invention relates to the technical field of ship engineering hull structure design, in particular to a conformal design method for platform-related equipment and structures in the integrated design process of ship platform structures. Background technique [0002] At present, the design of the internal platform structure of the ship and the distribution of platform-related equipment (such as air ducts, cables, condensation pipes, lubricating oil pipes, etc.) are carried out separately by the ship structure and ship system, so the equipment and platforms are generally discrete structures. Taking the air duct as an example, the air duct is usually hung under the platform structure with a fixed bracket, and in order to reduce the structural vibration noise, the vibration isolator is installed on the bracket to reduce vibration, but the vibration isolator and its bracket take up a lot of space, and The fixed support structure is easy to cause adverse e...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a ship equipment and platform-related equipment for the above-mentioned problems in the prior art that occupy a large space during the design process, difficult construction, and easy interference resulting in design rework. Structural conformal design method. When the equipment is arranged inside the ship, the method is integrated with the ship platform structure, that is, the equipment is structurally processed and the platform structure is conformally designed to meet the structural strength of the ship platform. The design scheme to realize the lightweight design of the ship platform structure and maximize the layout space without affecting the requirements of rigidity and other conditions without affecting the installation, use and maintenance of equipment
