Spiraalvedru

Spiraalvedru, also known as a helical spring or coil spring, is a mechanical device typically made from a metal rod or wire coiled into a spiral or helical shape. Its primary function is to store mechanical energy when deformed, and to exert a force or return to its original shape when the load is removed. The way a spiraalvedru behaves is determined by its material properties, the geometry of its coil, and the type of load applied.

Spiraalvedru can be classified into several types based on their configuration and the direction of force they are designed to resist or apply. Compression springs are designed to be compressed, tension springs are designed to be stretched, and torsion springs are designed to be twisted. The wire or rod used can be round, square, or rectangular in cross-section. The pitch of the coil, which is the distance between adjacent coils, also influences the spring's behavior.

These springs are ubiquitous in mechanical systems. They are found in everyday objects such as ballpoint pens, mattresses, and door hinges, as well as in more complex machinery like automotive suspensions, industrial equipment, and aerospace applications. Their ability to absorb shock, dampen vibrations, maintain pressure, or provide precise force makes them indispensable components in engineering. The design and manufacturing of spiraalvedru require careful consideration of factors like load capacity, fatigue life, and environmental conditions to ensure optimal performance and longevity.
