Variable Force Spring Curve After Long Dwell
State the held position, environment and dwell duration, then record first restart and the subsequent force profile.
State the held position, environment and dwell duration, then record first restart and the subsequent force profile.
The fixture and assembled mechanism can introduce rate-related resistance. A curve without speed is difficult to reproduce.
Mounting offsets can shift the curve relative to the mechanism’s working positions. Specify both part and assembly reference states.
The combined effects of profile change, friction and restart can be more visible there than during a continuous sweep.
Specify tight limits only where function requires them, while preserving enough information to define the useful curve.
State the allowable force band and the position where it applies, including user effort and attachment loads.
