Backlash

(Template Builder) Driveline Components -> Translational/Rotational Backlash -> New/Modify Comprehensive Help

The dialog box has two modes: create and modify.

Adams Driveline models the lash with a force component that exerts a force according to the values you specify for backlash, contact stiffness, and damping. When the angular displacement of the two parts is less then the specified backlash, the force is zero. When the angular displacement is greater than zero, the force is proportionate to the stiffness and damping value.

For the option:	Do the following:
Tips on Entering Object Names in Text Boxes.
Backlash Name	If creating a backlash, enter a string to define its name. If modifying a backlash, enter the database name of an existing backlash.
I Part	Enter the name of the I part on which the backlash will act.
J Part	Enter the name of the J part on which the backlash will act.
Construction Frame	Enter the name of an existing construction frame. If the backlash is rotational, it will be used to define the z-axis along which the backlash torque will act, if it is translational it will define the axis of the translational force.
Backlash	Enter a real number that defines the angular (for rotational) or linear (for translational) backlash in the units system specified in the pull-down menu on the right side of the text box.
Contact Stiffness	Enter a real number that defines the contact stiffness. Once the maximum allowed backlash is reached, Adams Driveline uses this parameter to model the contact force between the two parts.
Contact Damping	Enter a real number that defines the contact damping. Once the maximum backlash is reached, Adams Driveline uses this parameter to model the contact force between the two parts.
Sharpness Factor	Enter a real number that defines the Sharpness Factor. Once the maximum allowed backlash is reached, Adams Driveline uses this value to model the contact force between the two parts. For more information about sharpness factor see Backlash Components section.
Lock	Select it if you want to deactivate your backlash element by superimposing a rotational/translational motion.
	Select to display the Modify Entity Comments dialog box, where you can add multi-line comments to any entity to describe its purpose and function. Learn about Recording Comments.
