modelCutTorque

Measure cut torque

Extends from Internal.PartialCutTorqueSensor (Base model to measure the cut force and/or torque between two frames, defined by components).

Information

The cut-torque acting between the two frames to which this model is connected, is determined and provided at the output signal connector torque (= frame_a.t). If parameter positiveSign = false, the negative cut-torque is provided (= frame_b.t).

In the following figure the modeling and animation of this sensor is shown.

Parameters

TypeNameDefaultDescription
Booleananimationtrue= true, if animation shall be enabled (show arrow)
BooleanpositiveSigntrue= true, if torque with positive sign is returned (= frame_a.t), otherwise with negative sign (= frame_b.t)
