Variable Force Spring Partial-Stroke Duty

Quick answer: It may not reproduce the relevant contact pattern or transition behavior. Include the actual partial-stroke sequence.

Does full-stroke qualification cover repeated short-stroke use?

A short working interval can repeatedly stress or contact the same region. If the interval crosses a profile transition, restart and reversal matter particularly. Define ordinary use and occasional full extension as separate duty cases.

A practical verification method

Run the declared partial-stroke pattern and compare local force and contact condition with the full-stroke result.

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.
