To add your first kinematic-chain – a Part that rotates at constant angular velocity - also called Uniform Rotary Motion.
To learn the different methods to do each step.
Each step is explained in detail - almost tedious detail!
Note: In an actual machine, a 'Part that Rotates', may be a: shaft, cam-shaft, indexing shaft, turret, star-wheel, ...
Term : |
Description and definition. |
Element : |
Physical and abstract objects we add to the model to build the machine. |
Plane : |
A flat surface, defined by its XY-axes. The Front-View (F3) of a Plane is normal to its XY-axes. |
Mechanism-Plane : |
The Plane to which the active Mechanism-Editor has been added. |
Mechanism-Editor : |
The graphic-area, the Mechanism name-tab, and the Contextual toolbars. |
Base-Part : |
The fixed frame in each Mechanism-Editor. The Base-Part has a rectangular Part-Outline. |
Part : |
The fixed or moving rigid-bodies. Parts we add to model have an oval Part-Outline. |
Kinematic-Joint : |
Kinematic-Joints constrain the relative movement between two Parts. |
Pin-Joint : |
A Kinematic-Joint that constrains Points in two different Parts to be coincident on the Mechanism-Plane. |
Slide-Joint : |
A Kinematic-Joint that constrains Lines in two different Parts to be coincident on the Mechanism-Plane. |
Kinematic-Chain : |
Two or more Parts, joined with one or more Kinematic-Joints. |
Kinematically-Defined Part (or chain) : |
A Part (or Chain) that moves in a manner as specified by at least one Motion-Part. |
Motion-Part : |
A Part whose position and motion is specified by a Motion-Dimension FB. |
Motion-Dimension FB : |
A Function-Block that specifies the angular (angle) or linear position (distance) of a Part relative to a different Part. |
Linear-Motion FB : |
A Function-Block whose output increases at the same rate as the Master-Machine-Angle. |
Master-Machine-Angle : |
The machine-clock that, when you cycle the model, increases at a constant rate from 0 to 360, again and again. |
Rocker : |
A Motion-Part that rotates about a Pin-Joint. |
Crank : |
A Rocker whose motion is constant angular velocity. |
