modelSignTorque
Constant torque changing sign with speed
Extends from Rotational.Interfaces.PartialTorque (Partial model of a torque acting at the flange (accelerates the flange)).
Information
Model of constant torque which changes sign with direction of rotation.
Please note:
Positive torque accelerates in both directions of rotation.
Negative torque brakes in both directions of rotation.
Around zero speed regularization avoids numerical problems.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | useSupport (from PartialElementaryOneFlangeAndSupport2) | false | = true, if support flange enabled, otherwise implicitly grounded |
| SI.Torque | tau_nominal | Nominal torque (if negative, torque is acting as load) | |
| Modelica.Blocks.Types.Regularization | reg | Modelica.Blocks.Types.Regularization.Exp | Type of regularization |
| SI.AngularVelocity | w0 | Regularization below w0 |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Flange_b | flange (from PartialElementaryOneFlangeAndSupport2) | Flange of shaft | |
| Support | support (from PartialElementaryOneFlangeAndSupport2) | Support/housing of component |
Components
| Type | Name | Default | Description |
|---|---|---|---|
| SI.Angle | phi (from PartialTorque) | Angle of flange with respect to support (= flange.phi - support.phi) | |
| SI.AngularVelocity | w | Angular velocity of flange with respect to support (= der(phi)) | |
| SI.Torque | tau | Accelerating torque acting at flange (= -flange.tau) |
