Coil Spring Engineering Design Application

Coil Spring Review

A Coil spring is any spring formed into a helical coils shape. Coil springs are used in compression, tension, torsion. The term coil spring in generaly used to describe a spring commonly used in automiblies used to absorb load and deflection variqations fron the vehical suspension. The AUtomotive type coil spirng is used between the sutopmotive freme and control arm , the axle and chassis, or around a MacPherson strut.

Coil springs may be shaped conical, spiral wound and exhibit a constant rate or variable rate spring factor.

The following are three typical types of coil springs and thier applications:

Tension (extension) coil springs are designed to resist stretching or tension loading. Tension coil springs typicaly utilize a hook or eye feature to secire the coil spring at each end.
Compression coil springs are designed to resist compression. Compression coli springs typically are utilized to resisit compression loads. The ends of a compression coil spring are normally ground flat.
Torsion coil springs are deisgn to absorb torsional loads. The ends of a torsion coli spring normally have striaght or hooked features.

Coil springs are formed by twisting a wire around a shaped form.
