Previous example:The angle of the feet do not follow the angle of

the pedals during rotation.

The rotation angle of the pedals is set to a

1:1 ratio of the crank rotation within thekinematic set.


While the Manikin may be attached to thepedals, it is drivenby the kinematic set andtherefore not editable inside the Kinematicfunction.

The main problem to solve in this exampleis to get the pedals to follow the feet.

Step 5: Create a Product for a stick figure

kinematic mechanism.



6/15


There will be four Parts to build the

kinematic mechanism:


Crank Rotation

LH Pedal Simulator

RH Pedal Simulator


7/15


Other Parts within the Product will be:

Manikin (Ergonomic Design & Analysis)


e oo mu a or Right Foot Simulator

LH Pedal (3D Part)

RH Pedal (3D Part) Laws


8/15


The kinematic mechanism will start with the

Fixed Part and two Gear Joints between theFixed, Crank Rotation, and Pedal Sim Parts.



9/15


The LH & RH Pedal Sim Parts consist of a

centerline for the pedal pivot and a point.

They will be used to attach the Manikin to the

kinematic mechanism as in the revious exam le.

Step 6: Load the Manikin from the previous

example.



11/15


Ensure the DOF values for the Feet, Legs,

& Thighs are correct and symmetric beforelocking the DOF.



12/15


Open Human Posture Analysis. Lock the

Feet DOF 1 & 2, Leg DOF 3, & Thigh DOF 2.You MUST LOCK

the DOF eachtime ou read the


If you run thekinematic setwithoutdoingthis, you mayexperience

unwanted results!

A helpful tip at this point would be to Save a

Manikin Profile in the desired position.You MUST LOCK

the DOF each


Product!

If you save aManikin profile

after locking theDOFs, when thatprofile is loaded

correctly, itmaintains these

locked DOFs
