Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This model demonstrates the effect of a backlash on eigenfrequency, and also that the damping torque does not lead to unphysical pulling torques (since the ElastoBacklash model takes care of it). Furthermore, it shows the differences of the ElastoBacklash and ElastoBacklash2 components (the ElastoBacklash2 component generates events when contact occurs and the torque changes discontinuously).

Components (9)

fixed1

Type: Fixed

Description: Flange fixed in housing at a given angle

springDamper

Type: SpringDamper

Description: Linear 1D rotational spring and damper in parallel

inertia1

Type: Inertia

Description: 1D-rotational component with inertia

fixed2

Type: Fixed

Description: Flange fixed in housing at a given angle

elastoBacklash

Type: ElastoBacklash

Description: Backlash connected in series to linear spring and damper (backlash is modeled with elasticity)

inertia2

Type: Inertia

Description: 1D-rotational component with inertia

fixed3

Type: Fixed

Description: Flange fixed in housing at a given angle

elastoBacklash2

Type: ElastoBacklash2

Description: Backlash connected in series to linear spring and damper (backlash is modeled with elasticity; at start of contact the flange torque can jump, contrary to the ElastoBacklash model)

inertia3

Type: Inertia

Description: 1D-rotational component with inertia
