|---|---|
Tips on Entering Object Names in Text Boxes. Tips on Entering File Names in Text Boxes. | |
Bumpstop Name | If creating a bumpstop, enter a name for it. If modifying a bumpstop, enter its database name. |
Bumpstop Type | Select the type of bumpstop: ■Internal - Select this option to create a line-of-sight force, typically used when the bumpstop is installed internal to a shock or strut. ■External - Select this option to create a force vector, typically used when the bumpstop is installed separate from a shock or strut. |
I Part | Enter the name of the I part on which the bumpstop will act. |
J Part | Enter the name of the J part on which the bumpstop will act. |
I Coordinate Reference | Specify a Coordinate Reference to locate the point on the I part at which the bumpstop will act. |
If you selected Bumpstop Type: Internal, the following option is shown: | |
J Coordinate Reference | Specify a coordinate reference to locate the point on the J part at which the bumpstop will act. |
If you selected Bumpstop Type: External, the following three options are shown: | |
Bumpstop Orientation | Specify orientation type for bumpstop’s I marker. Global: Set force vector’s I marker orientation to global Line-Of-Sight: Set force vector’s I marker orientation along line of sight of two coordinates (I Coordinate Reference and J Construction Frame). Note: Line-of-Sight orientation only applies to design position. |
J Construction Frame | Specify a construction frame to locate and orient the plane on the J part at which the bumpstop will act. The Z-axis of the construction frame defines the plane normal. Note that the positive Z-axis should point toward the I Coordinate Reference, though they do not need to be perfectly aligned. |
Metal-to-Metal Coord Ref | Enabled only for XML property files. This is an optional input. Specify a coordinate reference to locate the point on the I part at which the metal-to-metal contact force will act. Otherwise if a metal-to-metal rate is specified, it will be applied at the I Coordinate Reference. |
Reference Part | Select either I Part or J Part as the reference part in the penetration and clearance measures. |
Property File | If creating a bumpstop, note that the text box by default contains the file mdids://acar_shared/bumpstops.tbl/mdi_0001.bum. You can use this file or select another one from your databases. If modifying a bumpstop, specify the property file that contains the force-deflection relationship for the bumpstop. |
Clearance/Impact Length | Select a method to specify when the bumpstop force activates: ■Clearance - Specify the distance the I coordinate reference must travel towards the J coordinate reference before the bumpstop force activates (relative to the design position). ■Impact Length - Specify the length of the bumpstop. The bumpstop force will activate when the distance between I and J coordinate references falls below this length. |
Color | Select a color for the bumpstop graphic. |
Bumpstop Diameter Slider | Select the diameter of the bumpstop graphic. Note that the slider actually defines the ratio of the diameter to the length. Note: Because the bumpstop is not a part itself, and solely defines the force-displacement relationship between two parts, changing the bumpstop graphic diameter does not translate into different bumpstop properties. |
 | Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments: ■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box. ■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box. Learn about Recording Comments. |
 | Select to modify: While either tool is active, you cannot perform operations in the main window. After exiting either tool, you can resume working in the main window. |
 | Select to view property file information. By default, your template-based product displays this information in the Information window, but you can choose to display the information in a text editor. Learn about: |
