Calculate the motion and examine the results.
-
Click Calculate
(MotionManager toolbar).
- Right-click Mates
(MotionManager tree) and click Degrees of Freedom.The
Degrees of Freedom dialog box
provides an estimate of the degrees of freedom and redundant mates. For this
model with one actual degree of freedom, there are 12=1-(-11) redundant mates,
including the Piston Male Align mate.
You can view the
estimated mate redundancies from the modified name description,
(12) Redundancies, for
Mates

tree).

Close the dialog box and expand Results

The plot displays the reaction moment of the coincident mate
between the male piston and the connector. You expect the reaction moment to
peak at the same time that the piston moves through its maximum
displacement, which occurs at around 2.5 seconds in the motion simulation.
The calculated result plot does not indicate this.
The result plot is inaccurate for the following reasons:
- The model is overconstrained.
- The redundant Piston Male Align mate used to
calculate the plot is ignored.
