Description

This element consists of a backlash element connected in series to a spring and damper element which are connected in parallel. The spring constant shall be non-zero, otherwise the component cannot be used.

In combination with component IdealGear, the ElastoBacklash model can be used to model a gear box with backlash, elasticity and damping.

Parameters

    ElastoBacklash_0

  • c [N.m/rad] : Spring constant (c > 0 required) (c): Scalar.
  • d [N.m.s/rad] : Damping constant (d >= 0) (d): Scalar.
  • b [rad] : Total backlash (b >= 0) (b): Scalar.
  • phi_rel0 [rad] : Unstretched spring angle (phi_rel0): Scalar.

Ports

  • Port 1 at left position: implicit input fixedport numbered 1.
  • Port 1 at right position: implicit output fixedport numbered 1.
