Southpointe 275 Technology Drive Canonsburg, PA 15317 (T ) 72 72 (F) 72 Release 15.0 November 2013 ANSYS, Inc. The very small discrepancy noted on the reaction force is due to a few overlapping nodes on a boundary condition.ANSYS Fluent in ANSYS Workbench User's Guide ANSYS, Inc. The contour plot for contact friction stress shows zero results for time = 0.6 and 1 which makes sense, since the friction coefficient is essentially zero at these time points.Īnother sanity check is to check for reaction force through the frictional contact with the extraction method set to contact element option this also reveals zero (nearly zero reaction force at these time points). This command object uses the information in the table below to modify friction :Īs an example of the friction can vary, notice the friction coefficient is zero for time = 0.6 and time = 1.0.ĭuring the run, the output controls under Analysis Settings was set to Yes for Nodal Forces, Contact Miscellaneous and General Miscellaneous.Ī quick look at the contact results confirms our findings. The command object used to modify friction as a function of time is shown below. In this example presented, the friction is varied with time (to simulate it’s change through the load step).īelow is a graphic of the nonlinear contact between the Aluminum housing and steel ring gear. you can use the TBFIELD command in conjunction with the TB,FRIC. To define the friction that is function of temperature, time, normal pressure, sliding distance, etc. The friction coefficient is defined via the TB,FRIC command.

The example presented here will show how to use commands object within Workbench to vary friction coefficient. It further discusses varying friction coefficient in a multiple load step scenario, as well as implementing user defined friction using TB,FRIC with TBOPT = USER. It can be used to define coefficient of friction for both isotropic or orthotropic friction models. This section on the documentation describes defining contact friction using TB,FRIC which is a material property used with current technology contact elements. The ANSYS documentation has several references of doing this as listed under the Help section Mechanical APDL > Material Reference > Nonlinear Material Properties > Contact Friction as shown below. Currently, the ANSYS Workbench GUI does not support this capability directly however, it is possible to vary the friction coefficient using a command object.
There are situations in which it may be necessary to tweak friction coefficient in a nonlinear contact analysis during the simulation.
