Segment Mass
Every segment in a Visual3D model has a mass, which is used to calculate kinetic quantities.
Default Segment Mass
The default segment masses defined in Visual3D are based on Dempster's regression equations and are (relative to total body mass):
| Segment | Mass (% body mass) |
|---|---|
| foot | 0.0145 |
| shank | 0.0465 |
| thigh | 0.10 |
| hand | 0.006 |
| forearm | 0.016 |
| upper arm | 0.028 |
| pelvis | 0.142 |
| thorax/abdomen | 0.355 |
| head | 0.081 |
| trunk | 0.497 |
Modifying Segment Mass
Users can modify Segment Mass under the segment properties tab in Visual3D's model builder.
