StiffnessFor is a spring stiffness and design tool for engineers, students, and technicians who work with leaf springs and need quick, accurate calculations and record-keeping.
Who it is for
Mechanical and automotive engineers designing or checking leaf spring suspensions
Engineering students learning spring mechanics and stiffness formulas
Technicians and workshop staff evaluating spring specs and comparing materials
Anyone who needs stiffness (k), elastic energy, or load capacity estimates for leaf springs
What you can do
Leaf spring stiffness: Compute stiffness for semi-elliptic leaf springs from Young’s modulus, number of leaves, span, width, and thickness using the standard formula.
Quarter-elliptical springs: Get stiffness for cantilever-style quarter-elliptical leaf springs, typical in many suspension layouts.
Elastic potential energy: Calculate stored energy (E = ½ k x²) for a given stiffness and compression, and compare min/max compression ranges.
Material comparison: Compare common spring steels (e.g. 60Si2Mn, 55Cr3, SAE 5160) by modulus and allowable stress, and estimate relative load capacity for a chosen safety factor.
Design records: Save design titles, spring type, load case, target stiffness, and safety factor for later reference and review.
Typical use cases
Sizing or verifying leaf springs for cars, trucks, or trailers
Checking stiffness and energy in suspension or driveline homework or projects
Choosing or comparing spring materials and geometry before prototyping
Keeping a simple log of designs and parameters for different load cases
StiffnessFor uses standard engineering formulas and is intended for reference and estimation in design and study; critical applications should be validated by qualified engineers and appropriate standards.
