Variable Force Spring Energy from a Measured Profile

Quick answer: Integrate force over displacement through the actual working interval. Multiplying peak force by full stroke overestimates work for most changing curves.

How is linear work estimated for a variable profile?

Use consistent units and distinguish energy put into the mechanism from recoverable output when friction is present. A profile table supports a numerical estimate, but coarse spacing near a transition may miss important area. Label example calculations as illustrative.

Verification plan for variable force spring energy force displacement: recommended check, retained evidence and decision boundary
Original verification plan for this specific decision. Acceptance values must be agreed for the actual product.

Use the result in an engineering request

Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
