Quick answer: The fixture and assembled mechanism can introduce rate-related resistance. A curve without speed is difficult to reproduce.
Why should speed accompany a force report?
Compare like-for-like before concluding that the profile changed. Slow manual motion may show breakaway effects; faster motion adds other dynamic loads. The spring specification and system requirement should name the conditions relevant to use rather than selecting whichever test looks best.
A practical verification method
Repeat at the declared speeds with the same positioning and compare the functional points.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Repeat at the declared speeds with the same positioning and compare the functional points. | Resolve the specific question before approval |
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.
