    Spring is a kind of elastic element widely used in the mechanical and electronic industries. Spring can produce greater elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state, and the deformation energy is transformed into mechanical work or kinetic energy.The ratio of load and deformation of the spring is called spring stiffness.  There are many kinds of springs. They are used in various fields. According to the deformation condition, they can be divided into three kinds: spring, spring and spring.Compression spring compression spring (springs) is under axial pressure of the spiral spring, it is used in the data section for more rounded, useful...

    Compression springs are frequently seen and used in daily life. The main principle of compression springs is to provide a hand to the machine and drive it to work.The compression spring has a certain damping capacity, because the product's elastic force is not a fixed value, so every time it is used, there will be a return force, and the force is not a fixed size, which to some extent has the ability to slow down the vibration.As an example, now the car is installed above a compression spring, you will find when driving, its speed is greatly improved, and the movement process there is no sound, you don't need to use a lot of power, can make the speed of the car, this is the charm of compression spring, because it's there, so now in the car production technology is more and more perfect, th...

At first, during the experiment, Hooke found that the weight added to the spring was proportional to the elongation of the spring, and he tested his conjectures by many experiments. In 1678, Hooke wrote a spring paper, which introduced the results of experiments on elastic objects, laying the foundation for the development of material mechanics and elastic mechanics.Spring dynamometerIn the early nineteenth Century, under the premise of a lot of experimental work in the former, British scientist Thomas Yang summed up the research results of Hooke and others, pointing out that if the elongation of the elastomer exceeds a certain limit, the material will break, and the law of elastic force is no longer applicable, and clearly points out the scope of application of the law of elastic force.

Like most other basic mechanisms, metal springs have existed for a long time in the bronze age. Even for metals, wood is used as a structural member of flexible bow and arrow and military catapult. In the Renaissance, precise clocks made precision springs the first necessity. In Fourteenth Century, we saw the precise clock of revolutionary astronomical navigation developed. The world's exploration and conquest of European colonial powers continue to provide impetus for watchmakers "science and art." The other area of the firearm promotes the development of the spring. At the dawn of the industrial revolution in eighteenth Century, a large, accurate and cheap spring was proposed. Whereas the watchmaker's spring is often made by hand, the spring mass production is made of piano ste...

Torsional springs are a kind of helical springs, which mainly produce torque or rotational force. The end of the torsion spring is fixed to other components. When other components rotate around the center of the spring, the spring pullback them back to the initial position. Although this spring is called torsion spring, it is subject to bending stress rather than torsional stress. The torsion spring can store and release angular energy or fix a device in a static way by rotating the force arm around the middle axis of the spring body. Torsion springs are usually tight, but there is pitch between spring rings to reduce friction. They produce resistance to rotating or rotating external forces. According to the application requirements, the rotation direction (clockwise or counterclockwise) o...

Springs can also be classified by how they’re made. The first spring that comes to most people’s minds is probably a metal coil spring, also known as a helical spring. However, there are many other types. Even an elastic band can be considered a variable rate spring, since it stores mechanical energy.Coil SpringsLightweight coil springs are made by forming metal wires on an CNC coiling machine. The multi-axis CNC control allows you to create variable pitches and end conditions only limited by your imagination. Springs that come off the coiling machines do not have springy properties. They need to be heated to a high temperature (typically 500 degrees Fahrenheit or more) to relieve stress, then quenched to create shape memory.In contrast, when making heavy duty coil springs, the wire is hea...

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.Linear springsLinear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and it stays constant, no matter the spring’s deflection. This is why linear springs are also known as constant rate springs.Variable rate springsOn the other hand, a variable rate spring doesn’t have the ...
