About Position Analysis
Click Mechanism Analysis to open the Analysis Definition dialog box and create, edit, and run your analyses.
A position analysis is a series of assembly analyses driven by servo motors. Only motion axes or geometric servo motors can be included in position analyses. Force motors do not appear in the list of possible motor selections when adding a motor for a position analysis.
Position analyses were called kinematic or repeated assembly analysis in previous releases of Mechanism Design.
If you edit an analysis that you created as a kinematic or repeated assembly analysis in a previous release of Mechanism Design, it will be regenerated as a position analysis.
A position analysis simulates the mechanism's motion, satisfying the requirements of your servo motor profiles and any joint, cam-follower, slot-follower, or gear-pair connections, and records position data for the mechanism's various components. It does not take force and mass into account when performing the analysis. Therefore, you do not have to specify mass properties for your mechanism. Dynamic entities in the model, such as springs, dampers, gravity, forces/torques, and force motors, do not affect a position analysis.
Use a position analysis to study:
Positions of components over time
Interference between components
Trace curves of the mechanism's motion
* You can capture a mechanism's motion as a standard part by creating a motion envelope.
