Browsers supply a great deal of view-related functionality by listing the parts of a model in a tabular and/or tree-based
format, and providing controls inside the table that allow you to alter the display of model parts.
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing
parts. The current capabilities are focused on stiffening parts.
Rider plays an important role in two wheeler dynamics. To capture the effects of rider on a vehicle, it is important
to have a good human body multi-body dynamics model.
This suspension consists of double trailing arms, pivoted symmetrically at the bottom end
of the steering column. The inline spring damper system is mounted on the trailing arm on
either side. The wheel is suspended on the rear end of the trailing arm.
Model Use
The Double Side Trailing Link Suspension system can be used in front half vehicle or full
vehicle models of a two wheeler. The default geometry and mass approximate that of a two
wheeler scooter, but the model and data can be revised to reflect any size two wheeler.
Note:
The wheel body represents the mass and inertia of the tire and
the rim.
The wheel hub body represents the mass and inertia of other rotating bodies such as
a brake rotor. The wheel hub and brake rotor have no associated graphics.
The wheel and wheel hub parts use the Wheel center location as the center of
gravity.
The image below shows the Project browser view of the systems on a fully populated front
suspension model. The Double Side Trailing Link Suspension system has six “child”
systems.
Points
Points locate the joints and bushings that connect the
suspension bodies to one another. The image below shows the principal points for
the Double Side Trailing Link Suspension.
