Compression Spring Design Formulas

Being one of most basic spring the coil compression spring has undergone various tests and studies which allowed to come up with a formula based on experiments only and can be viewed as a rule of thumb but has been regarded as highly accurate that connect the major coil spring parameters. In determining the total number of coils in the spring the calculator assumes that the ends of the spring are squared.

Compression spring design formulas.

The formulas and calculations required to work on a coil compression spring design. These formulas were elaborated and corroborated making it possible to calculate a compression spring design. Following are just a few of the most basic formulas for getting a head start on compression spring design. Spring design and engineering formulas and knowledge menu.

The other end types provided on our compression spring calculator are closed and grounds. The compression spring design formulas to calculate its physical dimensions are provided below as well as how to choose a material type. Compression spring design outside diameter 0 063 to 0 119 003 1 001 to 1 225 020 0 120 to 0 240 005 1 226 to 1 460 030 0 241 to 0 500 008 1 461 to 2 000 040 0 501 to 1 000 015 custom compression springs if you are unable to find a suitable spring in our stock. Bending applied spring stiffness constant equations and calculator.

The above formula is true for any compression spring. This calculator computes all parameters spring rate maximum load maximum stress solid height coil pitch coil angle wire length resonant frequency shear modulus and spring mass related to a compression spring from basic geometry and material data input. There are several types of compression spring ends types. Helical spring formulas and equations over 17 000 springs in stock.

This equation will determine estimate the spring rate k of a compression spring. Spring design menu spring suppliers and manufacturers. The spring constant k is function of the spring geometry and the spring material s shear modulus g where g is found from the material s elastic modulus e and poisson ratio n and d is the mean diameter of the spring measured from the centers of the wire cross sections. Call us for design assistance.

The compression spring formulas you are about to see are based on many years of research from the acxess spring staff. Accurate and effective spring design can only be accomplished in today s world using computer programs capable of running hundreds of simultaneous calculations. This calculator will determine the spring rate constant related to a compression spring from basic geometry and material data input. The most popular ends are closed and squared ends.
