| def qualification.analysis.hysteresis_analysis.effort_analysis | ( | params, | |

| ) |
Analyzes test effort.
To pass, our average efforts must lie within the tolerances of the min/max efforts and must have their std. dev. below the threshold (sd_max). All percentage quantities are calculated in percent of difference in effort: sd_value = numpy.std(effort) / (numpy.average(positive) - numpy.average(negative))
Effort tolerances is given by "tolerance". SD tolerance given by "sd_max". Both tolerances given in percent of effort.

Checks slope of test data (effort v.
position)
Some components have a "slope" to their position/effort curves. This checks that the slope is within range and the intercepts are OK. Slope value is given by "slope" field of params. Tolerance from "sd_max" Intercepts are "pos_effort" and "neg_effort" fields. Tolerance from "tolerance".

| def qualification.analysis.hysteresis_analysis.wrist_flex_analysis | ( | params, | |
| data | |||
| ) |
Analyzes flex effort during wrist difference test.
The nominal flex effort during a wrist roll is zero. This helps determine wrist symmetry. Flex effort values must be within tolerance: * flex_max - Maximum allowable flex effort value * flex_sd - Std. dev. of the flex effort * flex_avg - Average value of flex effort All measured values must be less than their corresponding parameters. All parameters given in units of effort (Nm)
