Backlash connected in series to linear spring and damper (backlash is modeled with elasticity)
Modelica Standard Library
The Rotational Elasto Backlash (or Elasto Backlash) component consists of a backlash element connected in series with spring and damper elements which are connected in parallel. The spring constant must be positive.
In the backlash region −b2≤φb−φa−φrel0≤b2 no torque is exerted. Outside of this region, contact is present and the contact torque is basically computed with a linear spring/damper characteristic.
If the backlash parameter b is smaller than bε, the backlash is ignored and the component reduces to a spring/damper element in parallel.
During initialization, the backlash characteristic is replaced by a continuous approximation in the backlash region.
