As one of the most efficient energy storage devices available, helical compression springs are the most common spring configuration in the marketplace today. From automotive engines to major appliances, they are found in countless applications.
Though, they are typically manufactured from round wire in a cylindrical shape, compression springs are extremely customizable. Square, ovate, rectangular and other non-round cross section wire can be fashioned to meet differing requirements. Additionally, the spring can be altered to conical, hourglass or barrel shape among other profiles. In this way, dynamic resonance conditions or height restrictions can be addressed. Variable pitch between the coils provides different spring rates throughout the operating range of the spring and aid in minimizing resonate surging and vibration. Because of the number of compression spring characteristics that can be tailored to specific circumstances, this type of spring represents a flexible design approach to force resistance and energy storage.
