How to Drive Your Train

How to Assemble your Train with the track:

1. Constrain train to track using:

a. Offset mate with bottom of train to top of track (.4 in)

b. Offset flush side of train to side of track (.7 in)

3. Put Work Plane into wheel part file that is perpendicular to the front of the wheel

4. Bring in 3 more pieces of track

5. Change grounding of train (ground a track piece, un-ground the train)

6. Angle constraint on Left wheels of 0 deg (same for right)

Angle constraint on top of linkage arms to top of track 0 deg

7. Opposite side wheels with 180 (may be 0) deg angle constraint to have arms up at opposite times

8. Angle of a wheel with back of train 0 deg

Note: change f(x) parameters to be renamed “crank” (remember which wheel)

9. Flush back of train with back of track

Note: change f(x) parameters to be renamed “linearz”

linearz = (crank/360 deg)*(2.25 in * 3.14 ul)

10. Do your Drive constraint on whichever wheel you used:

Start 0 End 2000 deg delay 0

Increment 10+
