For Music Wire is 11492970.929 psi

Wire Diameter (d)

0.048 inches

Active Coils (n)

21.5

Mean Diameter (D)

0.452 inches

Step-by-Step Calculation

  1. Calculate d^4: 

d^4 = (0.048)^4 = 0.048 × 0.048 × 0.048 × 0.048 = 0.000005308

  1. Calculate D^3: 

D^3 = (0.452)^3 = 0.452 × 0.452 × 0.452 = 0.092356

  1. Calculate 8 ⋅  D^3 ⋅ n: 

8 ⋅ D^3 ⋅ n = 8 × 0.092356 × 21.5 = 15.883

  1. Calculate G ⋅ d^4: 

G ⋅ d^4 = 11492970.929 × 0.000005308 = 61.028

  1. Calculate the spring rate k:

k = Gd^4 ÷ (8D^3 * n) = 61.028 ÷ 15.883 ​ = 3.84

So, the spring rate k is approximately 3.84 lbs/in

Hooke's Law is a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance. The formula is given by:

F=k⋅x

Where:

  • F is the force applied to the spring (in pounds or Newtons),

  • k is the spring constant or spring rate (in pounds per inch or Newtons per meter),

  • x is the displacement or travel of the spring from its equilibrium position (in inches or meters).

For this example, we need to calculate the force F required to compress a spring with a spring rate k of 3.841 lbs/in, as seen in the past example, by a distance x of 1.5 inches.

Substitute the values into the modified Hooke's Law formula: 

F = Initial Tension ​+ k ⋅ x

Calculate the force due to the spring rate: 

k ⋅ x = 3.790 lbs/in × 3 in = 11.370 lbs

Add the initial tension to the force due to the spring rate:

F = 2.128lbs + 11.370lbs = 13.498lbs

The total force required to extend the extension spring by 3 inches, considering the initial tension of 2.128 lbs and a spring rate of 3.790 lbs/in, is 13.498 pounds.

Dimensional Constraints

Springs must often fit into compact spaces while maintaining their functionality. This requires precise control over dimensions, including wire diameter, coil diameter, and the number of active coils. The challenge lies in balancing these dimensions to achieve the desired spring rate and load capacity without compromising the spring's durability.

Using Acxess Spring's 3D CADs, designers can create detailed models of springs, allowing them to visualize and adjust dimensions before manufacturing. This reduces the risk of errors and ensures that the spring fits perfectly within the designated space.

Load Requirements

Springs must be designed to handle specific loads without permanent deformation or failure. This involves calculating the spring constant, stress distribution, and potential fatigue over repeated use. For example, compression springs in automotive suspensions must endure thousands of compression cycles while maintaining their performance.

Innovative simulation tools, like the Online Spring Force Tester provided by Acxess Spring, allow engineers to test spring designs under various load conditions virtually. By simulating real-world scenarios, designers can identify potential issues and optimize the spring's performance before physical testing.

Customization and Prototyping

Many applications require custom springs tailored to specific requirements. Creating custom compression springs, extension springs, torsion springs, or conical springs involves a detailed design process that can be time-consuming and costly. Each type of spring must meet precise specifications to function correctly in its intended application, whether it’s providing the necessary force, fitting into a limited space, or enduring specific environmental conditions. 

Acxess Spring offers advanced tools like 3D Blueprints and Online Spring Force Testers, which enable designers to quickly prototype and test custom springs.
