spring is an elastic member, which serves to absorb and accumulate mechanical energy.It is made of a material having high strength and elasticity.In order to maximize the stiffness of the spring, in its manufacture use high carbon alloy steel.In practice, there are situations when the elastic member is used in an environment having a high aggressiveness.In such cases, it must be made of stainless steel or bronze.The small size of the spring can navit wire.But the powerful elastic elements to make them more stamina necessary to make of annealed metal.In addition, after forming the spring are further tempered.By referring
loads which act on elastic members, they are divided into separate groups.There are spring:
-contractions;
-rastyazheniya;
torsion;
-izgiba.
design elements working in compression is designed to reduce their length under the influence of a particular load.The rest of the turns do not touch each other.Spring compression which may cause loss of its stability, is set in special glasses or mandrels.The ends of the element subjected to special polishing and coils located at the ends, compressed to the neighboring.
tension spring load is calculated, which is the consequence of an increase in its length.At rest, the turns of such elements are closed together.The design includes a spring ring or hooks to secure it.They are located at the ends of the end turns.
Springs torsion and bending deformation energy is converted, increasing the multiple elastic material from which they are made.This process is possible by increasing the length of the coils.
Spring rate is the amount of physical.It characterizes the labor force of the elastic member at one millimeter of tension or pressure.When this spring is proportional to the force feedback.The law enshrines the concept was discovered by physicist Robert Hooke in England.According to his theory, the extension of the spring is equal to the force acting on it.
elastic elements are used in various fields.For example, in the manufacture of spring mattresses are used, the construction of which is designed to operate under the influence of compressive forces.Thus for great comfort spring which is installed in places subject to the greatest deformation is maximal.Conversely, in the locations where the minimum pressure of the body, the spring is set with the least stiffness.
are widely used in the production of elastic elements of cars.They play a crucial role in almost the behavior of the vehicle on the roadway.Spring hangers are designed to create a force which prevents the body roll.In cases where the stiffness of such a spring is too great, the vehicle may unduly sway.This negative view of passengers every hole or bump in the roadway.In order to improve the controllability of the vehicle, it is necessary to reduce the stiffness of the suspension.Typically, selection of springs is carried out so that the shortest distance between its turns than six and a half millimeters.To determine the stiffness of the elastic element is possible using floor scales, hand press and a ruler.
currently often used a spring with a variable pitch of the entire length.With static load the entire element as a whole provides the necessary stiffness of the suspension.When increasing the impact strength occurs circuit turns having a smaller pitch and their working amount decreases.This increases the stiffness of the spring.In the production of sports cars are also using elastic elements with turns having different steps.It provides the greatest possibility of adjusting the chassis.
