The Kinematics-Tree shows the structure of each .
MechDesigner compiles the Kinematic-Tree automatically as you add the different Kinematic and Machine Elements to your model.
The header of the Kinematic-Tree has the name Mechanisms.
Note: If a small '+' sign does not show to the left of 'Mechanism', then click the
TOP-TIP - To find the kinematic-chain for a Part in your model:
|1.||Click the Kinematic Tree tab|
|2.||Click the Part in the graph-area|
The Kinematics-Tree will expand to show the element.
Structure of the Kinematics-Tree
|►||Kinematic-Chains [Solved and Unsolved]|
In the Kinematics-Tree, the kinematic-chains are either:
|A.|| Kinematic-Chain |
The of each kinematic-chain is equal to zero. You cannot 'drag' the Parts
The kinematic-chain is a kinematically-defined chain.
Explore these to find the Kinematic Sub-Assemblies [see below] and then the kinematic elements.
|B.|| Unsolved Mechs |
The Mobility of each kinematic-chains is greater than zero. You can 'drag' the Parts
You can also explore these kinematic-chains. However, you will see only Parts and Joints.
Example: Kinematics-Tree in Element-Explorer
Kinematic-Sub-Assemblies [Solved Mechanisms]:
|3.|| - all have two Parts and three Joints |
R : Revolute = Pin-Joint
P : Prismatic = Slide-Joint
S : Spherical = Ball-Joint
|4.|| - a Gear-Pair, a Joint and a Part |
|5.||Rack-Pinion / Pinion-Rack|
|6.|| - a Pulley-Path, Part and Joint|
