Loading

Loading is a term used to define a lumped mass to be attached to a part within the same template or in another template. The loading object consists of a general part, a mount part, an input communicator of type mount, and a fixed joint or one or more bushings. The loading object is a virtual object that allows you to modify the general part and attachment(s) independently. It is created as a single entity.

There are two basic types of loading objects:

■Cargo - general purpose loading object, such as luggage, with box graphics.

■Occupant - allows you to specify h-point location, and includes representative graphics of human occupants.

Both cargo and occupant can be attached to other parts using a single fixed joint or with one or more bushings. In Template Builder mode, you can toggle the attachment type between joint and bushing, and add or remove bushings using the Modify Loading dialog box. The inputs required for creating loading objects are a combination of inputs required for part and attachment definition.

You can also create different sets of loading configurations using:

Loading Configuration

The main purpose of a loading configuration is to associate loading objects with particular vehicle loading conditions. It helps you to organize different loading configurations of the vehicle. You can use loading configurations as filters on the loading objects available in the model. You can use configurations to easily toggle the activity a set of loading objects associated with it.

For example, loading configurations can be created for "Curb" and "Design" vehicle loading conditions, etc. It can also be used for grouping sets of loading objects. For example, you may want to create a loading configuration for all passengers, or all luggage and so on.

This eliminates the effort required in creating and maintaining templates/subsystems with different loading conditions.

Notes:

■In the Standard Interface, you cannot modify loading configurations. In the Template Builder, you cannot create a configuration with the name 'all'; it is created by default when you create any loading object.

■In the Template Builder, you should not deactivate a loading object's bushing/joint, general part, or mount part associated with that loading object.

■It is not recommended to copy loading objects or loading configurations, as it will lose associativity with its contents.
