1. What is Spring Solid Height?

Spring solid height is the length of a compression spring when it is compressed to the point where all coils are touching and no further compression is possible. It represents the minimum possible height of the spring under maximum load.

2. How Does the Calculator Work?

The calculator uses the solid height formula:

Where:

• \( Wire\ Diameter \) — Diameter of the spring wire (in)
• \( Coils \) — Number of active coils in the spring (count)
• \( Ends \) — Additional length contributed by the spring ends (in)

Explanation: The formula calculates the minimum compressed length by multiplying wire diameter by the number of coils and adding any additional length from the spring ends.

3. Importance of Solid Height Calculation

Details: Calculating solid height is crucial for spring design and application. It determines the minimum space required for the spring installation, ensures proper spring function, and prevents over-compression which can damage the spring.

4. Using the Calculator

Tips: Enter wire diameter in inches, number of coils as a count value, and ends measurement in inches. All values must be positive numbers (wire diameter > 0, coils > 0, ends ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between solid height and free length?
A: Free length is the spring's length when unloaded, while solid height is the length when fully compressed with all coils touching.

Q2: How does wire diameter affect solid height?
A: Larger wire diameter increases solid height as each coil takes up more space when compressed.

Q3: What are typical end types and their contribution to solid height?
A: Common end types include closed ends, ground ends, and open ends. Ground ends typically add the least to solid height while special end configurations may add more.

Q4: Why is it important to know the solid height in spring design?
A: Knowing solid height helps prevent spring damage from over-compression and ensures the spring will fit in the allocated space during maximum compression.

Q5: Can solid height be less than wire diameter × coils?
A: No, the solid height cannot be less than wire diameter × coils, but it can be equal to this value if the ends contribute zero additional length.
