When the parent node is Gear Pair, enter Wheel tooth stiffness as function of mesh cycle, kt,wh, and Pinion tooth stiffness as function of mesh cycle, kt,pn. The default expressions are (0[N/m])*mbd.grp1.thm_wh and (0[N/m])*mbd.grp1.thm_pn, respectively. The exact naming of the variables depends on the tags of the nodes in the model tree.

When the parent node is Worm and Wheel, enter Worm tooth stiffness as function of mesh cycle, kt,wm, and Wheel tooth stiffness as function of mesh cycle, kt,wh. The default expressions are (0[N/m])*mbd.grp1.thm_wm and (0[N/m])*mbd.grp1.thm_wh, respectively. The exact naming of the variables depends on the tags of the nodes in the model tree.

When the parent node is Rack and Pinion, enter Rack tooth stiffness as function of mesh cycle, kt,rk, and Pinion tooth stiffness as function of mesh cycle, kt,pn. The default expressions are (0[N/m^2])*mbd.grp1.um_rk and (0[N/m])*mbd.grp1.thm_pn, respectively. The exact naming of the variables depends on the tags of the nodes in the model tree.

For Varying contact ratio, select Maximum contact ratio — 2, or 3. Also enter the Next tooth engagement position in mesh cycle, ζ. The value of ζ must vary between 1/2 and 1 when Maximum contact ratio is set to 2 and between 1/3 to 1/2 when Maximum contact ratio is set to 3.

In case the parent node is Gear Pair, select the Total stiffness as function of — Wheel mesh cycle, Wheel full revolution, Pinion mesh cycle, or Pinion full revolution.
|
•
|
In case the parent node is Worm and Wheel, select the Total stiffness as function of — Worm mesh cycle, Worm full revolution, Wheel mesh cycle, or Wheel full revolution.
|
•
|
In case the parent node is Rack and Pinion, select the Total stiffness as function of — Rack mesh cycle, Pinion mesh cycle, or Pinion full revolution.

Enter Total stiffness, kg. The default expression of total stiffness depends on the selection in previous input; for example, it is (0[N/m])*mbd.grp1.thm_wh when Wheel mesh cycle is selected. The exact naming of the variable depends on the tags of the nodes in the model tree.
