The Properties of Compression Springs - Designing

Properties of compression springs. A feature that can set compression springs apart from other types of spring is the tightness of their coils. Compression springs are less tightly coiled than torsion springs and work in the opposite way to other springs – whereas some springs hold things together, compression springs keep things apart.

Compression springs, parameters, characteristics, materials

Compression Springs. De (external diameter): External diameter of a spring can be calculated by adding the doubled wire diameter to the internal diameter of a spring. Tolerance for this parameter is (+-)2%(indicative). H (hole): This is the minimum diameter of the hole in which spring can work.

Compression Spring Properties - Compression Spring Load

Compression Spring Hysteresis: The mechanical energy loss that occurs as a result of the spring ends' tendency to rotate when compressed during cyclic loading and unloading.

Springs – The Physics Hypertextbook

It's about springs — coil springs — the kind of spring found in a car's suspension or a retractable pen, the kind that look like a pig's tail or a lock of curly hair. Coil springs are also known as helical springs since the mathematical name for this kind of shape is a helix.

Spring (device) - Wikipedia

Tension or extension springs are designed to become longer under load. Their turns (loops) are normally touching in the unloaded position, and they have a hook, eye or some other means of attachment at each end. Compression springs are designed to become shorter when loaded. Their turns (loops) are not touching in the unloaded position, and they need no attachment points.

Upon closure, use a design factor of 1.2 guarding against yielding. Select the smallest gauge W&M (Washburn & Moen) wire. 1/2/2015 2:11 PM

What are Stainless Steel Compression Springs? - SMSC

These springs are made from helically formed coils. There is a pitch in between every coil. Whenever an external force or load acts on the springs and compress them, the pitch between the coils pushes the spring back to its original position. Thus, once the external force is removed, the compression spring regains its original shape.

Compression Springs - Materials, Engineering, Quality - MW

Springs – The Physics Hypertextbook

Elasticity is the property of materials to return to their original size and shape after being deformed (that is, after the deforming force has been released). Since it is really a property of materials, a more complete discussion will have to wait until later. For now we'll stick to a simple elastic system (the coil spring) and a simple law (Hooke's law).
