 Parameters(4) Default Remark StribeckTorque 2 The stribeck friction is set by the parameters StribeckTorque [Nm] and StribeckFriction[1/Rad/s] StribeckFriction[1/Rad/s] 2 The stribeck friction is set by the parameters StribeckTorque [Nm] and StribeckFriction[1/Rad/s] ProportionalFriction[[Rad/s]/Nm] 1 The angular speed proportional friction (>0) is set by the parameter ProportionalFriction [ [Rad/s] / Nm ] CoulombFriction[Nm] 1 The coulomb friction is in [Nm/rad/s] and is constant and set by the parameter CoulombFriction[Nm]

 Function Combined Stribeck, Coulomp and Proportional friction. The angular speed proportional friction is set by the parameter ProportionalFriction [ [Rad/s] / Nm ] The coulomb friction is in [Nm/rad/s] and is constant and set by the parameter CoulombFriction[Nm] The coulomb friction[Nm] and is positive for positive angular speed and negative for negative angular speed. The stribeck friction is defined as StribeckTorque*exp(-StribeckFriction*AngularSpeed) and is defined in [Nm] At an angular speed of 0 [Rad/s] the friction is at a maximum with Mstiction. For a large value of the angular speed, the stribeck friction is reduced towards zero. The stribeck friction is set by the parameters StribeckTorque [Nm] and StribeckFriction[1/Rad/s]
