A frame is what?

Every self-respecting scholar can easilycrack down on a dozen other scanwords. But even the pros sometimes meet with questions that are difficult to answer. In such situations, even the famous "mathematical" method of selecting letters does not always help. And surely not one of you has encountered issues that affect the term "frame." These are quite difficult tasks, and to answer them, one has to plunge into the history of shipbuilding.

What is the frame?

The term "frame" has come to Russian fromNetherlands and literally means "wooden rib". In reality, it is a transverse component of the power set of the hull of ships, where it acts as a stiffener.

With the development of machine building, the term becameIt is also used in the sphere of aircraft construction, where it designates a stiffener for the fuselage of an aircraft. As it became clear, the main role played by the frame is to give the vessel the necessary rigidity, be it air or sea.

Also this element of the power kit is usedTo fix the longitudinal components, which is necessary for the shell skin. It will be useful for the erudite people to know that the distance between the neighboring frames is called aspiration.

Frame types

There are two large groups, to which engineers divide all the frames: wooden and metal. Each type has a branched classification. Thus, wooden cross bars are divided into:

Bent, which consist of a solid wood massif. For their manufacture use trunks with natural curvature.
Fotoksovye, which are assembled from several components. This type of wooden crossbars was most widely used.

The two parts consists of a futocous frame: it's floret and directly futox. Flortimbers is the part that is attached to the keel of the ship - the longitudinal beam passing through the entire length of the ship. To him from both sides are attached fotoksy.

Metal products are divided into more classes. But most often allocate frames for the functions performed:

frame, whose task is to improve the strength of the ship and the connection of longitudinal bearing elements;
The main ones, which constitute the greater part of the total number of transverse bars, serve to sheathe the vessel.

The number of transverse power bars depends ondisplacement of the ship, its draft. Thus, the frame is not just a supporting element of the vessel, which gives the body rigidity. It also gives the ship a certain stability on the surface of the water.

Special type

In shipbuilding a special place is occupied bymidship-frame, despite the fact that it is constructive in no way different from other types of transverse power bars. This term is used during calculations, because it is located strictly in the middle of the perpendicular crossing the ship along.

Based on the location of the mid-frame,calculate the drag of the ship during the movement, as well as the coefficient of completeness of the hull, which characterizes the carrying capacity and speed of the ship. Will help understand what is the mid-frame, photo.

"They are closely related"

One of the main elements of the ship hull is the stringer, which performs several functions:

It senses the voltage from the total bending moment in the longitudinal direction.
Redistributes the load between adjacent transverse power bars.
Is an intermediate support for the frames.

In addition, stringers are basicelements involved in the skin of the hull or fuselage of the aircraft. Scanwords often come across questions about him, but now you know that stringers are a support for frames.
