The following procedure can be used to obtain center of gravity for any structure:
- Create your model and run the analysis.
- Use interactive database editing to export the following tables into Excel:
- MODEL DEFINITION > Connectivity Data > Joint Coordinates > Table: Joint Coordinates
- ANALYSIS RESULTS > Joint Output > Joint Masses > Table: Assembled Joint Masses
- In Excel, calculate the location of the center of gravity for each coordinate direction as a weighted average of joint coordinates, using the assembled joint mass as the weight. For example, the x coordinate of center of gravity can be calculated as follows:
Unknown macro: {math}
x_
Unknown macro: {cg}
=
Unknown macro: {sum x m}
/
Unknown macro: {sum m}
where
- x is x coordinate of individual joints
- m is mass of individual joints
