Note: If you cannot see the Kinematics-Tree in the Element-Explorer, click Rebuild now.

The Kinematics-Tree is the kinematic-structure of each kinematic-chain in the model.

We compile the Kinematic-Tree for you as you add Kinematic elements and Kinematic FBs to your model.

If you click on any kinematic-chain or element in the kinematic-structure, it will show as selected elements in the graphics-area.

You can use the Kinematic-Tree to Configure the Power Source of each kinematic-chain.

This icon is at the top of the Kinematic-Tree to the left of the name Mechanisms.

Note: If you cannot see Mechanisms, or explore the Kinematics-Tree, click Rebuild now.

The structure of the Kinematics-Tree is:

► Mechanisms:

► Kinematic-Chains

► Kinematic Sub-assemblies

► Kinematic Elements

►Unsolved Mechs

Kinematic-Chain

These kinematic-chains have a Mobility of zero(0). The kinematic-chains are kinematically-defined.

You can explore the kinematic-chains to find Kinematic Sub-Assemblies (see below) and kinematic elements.

Unsolved Mechs

These kinematic-chains have a mobility that is greater than zero(0). The kinematic-chains are not kinematically-defined.

Example: Kinematics-Tree in Element-Explorer

Kinematic-Sub-Assemblies (Solved Mechanisms ONLY):

These are compiled as:

2.Motion-Paths

3.Dyads - all dyads have two Parts and three Joints

We use a letter for each of its three joints:

R = Revolute-Joint = Pin-Joint

P = Prismatic-Joint = Slide-Joint

S = Spherical-Joint = Ball-Joint

a. RRR

b. RRP

c. RPR

d. PRP

e. RPP

f. Ram-R

g. Ram-P

h. SSR

i. SSP
