For the option | Do the following |
|---|---|
If you select Linear compliance, the following options will be displayed: | |
Chain | |
Name | Enter the chain name. |
Axis of Rotation | Axis of Rotation can be one of the following: ■Orientation ■Pick (Marker) ■Global Z ■Global X ■Global Y |
Reference location | Enter the reference location. This will be used as a reference frame to build other chain components. |
Geometry | |
Total Links | Select to directly specify the number of links in the chain. By default, this is un-selected and Adams Machinery will automatically calculates the number of links for which, based on the chain routing, the lowest positive tension will result. This field is primarily intended for use-cases where a maximum of 1 or 2 extra links beyond the default calculated number of links is desired. Be advised that such models may have difficulty reaching a static equilibrium solution. Use of the static funnel technique may be necessary to solve for equilibrium. |
Link type | Select one of the following: ■Uniform Link - Use this option, if all links are identical, to specify the mass properties of one link. ■Multi Links - Use this option to specify the material properties of two link designs, which will alternate in the chain. |
Chain pitch | Enter the distance, p, between the center lines of the two rollers on a chain link. |
Chain width | Enter the width of the chain links. |
Pitch to back | Enter the distance, h, from the pitch line of the chain link to edge of the plate that will be in contact with a guide. |

The Linear Chain Connection Parameters define the stiffness and damping of the bushing connecting two links. You can measure the chain tension by creating requests (see Create/Modify Chain Link Request or Create/Modify Span Request for Roller and Silent Chain. | |

This is the C[r1] value of a BUSHING statement. The damping is in force units * time units/length units. |
