Effect of number of winding turns on stainless steel small tension coil spring

The design and performance of stainless steel small tension coil springs are affected by many factors, among which the number of winding turns is an important parameter, which directly determines the mechanical properties, displacement characteristics and service life of the spring. Changes in the number of winding turns will have a significant impact on key properties such as spring tension, flexibility, and fatigue strength.
The number of windings directly affects the tension characteristics of the spring, that is, the restoring force provided by the spring under a specific stretch. The basic working principle of a coil spring is to store and release energy through the deformation of the spring. When the number of winding turns increases, the total deformation of the spring increases, but the force under unit tension will decrease accordingly.
The number of winding turns directly determines the maximum displacement capacity of the spring. The displacement capacity of a spring is the maximum tensile length it can withstand without plastic deformation or failure. More turns generally means greater displacement capability because the overall length of the spring is increased and the spacing between each turn is able to accommodate greater elongation.
The number of winding turns also has a significant impact on the fatigue performance of stainless steel small tension coil springs. Fatigue performance is a measure of a spring's ability to maintain normal working conditions without breaking or permanently deforming during repeated stretching.
The number of turns also determines the free length of the spring, which is the natural length of the spring when no external force is applied. As the number of winding turns increases, the free length also increases accordingly. This has important implications for spring installation and space design.
