Chains
This component describes a simplified chain model in its global behavior. This component does not model chain parts. It does, however, model the global behavior of the chain, which is a torsional load and a longitudinal force (tension).

Creating or Modifying Chains
To create or modify a chain:
1. From the Driveline Components menu, point to Chain, and then select New/Modify.
2. Press
F1 and then follow the instructions in the dialog box help for
Chain. 3. Select OK.
About Chains
A chain describes a force-based connection between two sprockets. In Adams Driveline you create a simple chain model in which no chain links are modeled. Adams Driveline models torsional and translational loads in the chain with a rotational spring damper and a single-component force.
If you want to take into account the backlash effect, you can connect each sprocket to the respective shaft with a
rotational backlash component.
If you want to have a transmission ratio different from 1:1, you can connect the output sprocket to another part with a kinematic gear component.
Adams Driveline creates the following forces between the input and the output sprocket:
■A rotational spring damper (acting between CM marker of the input sprocket and the CM marker of the output sprocket).
Note: | The reason why a rotational spring damper is used instead of a coupler is so that chain elastic characteristics can be taken into account. |
■A translational single-component force (acting between driving sprocket and driven sprocket).
The translational force expression is:
-TM(Input sprocket marker, output sprocket marker) / Input Sprocket Radius
If you decide to use the gear geometry (revolution) for sprockets, the radius will be deduced from that component. Otherwise, you will have to enter the value in the create/modify dialog box.
In the Standard Interface (see
Interface Modes), you can vary values for the following:
■Rotational stiffness
■Rotational damping
■Sprocket radius (in case gear geometry has not been used)
Subsystem Parameters
■Stiffness
■Damping
