Block

Purpose

World Frame

Provides the ultimate reference

frame in a model. All remaining

frames are defined with respect

to this frame. It is inertial and it

defines absolute rest.

Rigid Transform Applies a fi xed spatial relationship

between frames. This block defines

the offset distance and angle between

two frames.

Mechanism Configuration Identifies the gravity vector in a

model.

Solver Configuration

Provides essential simulation

parameters required to simulate the

model.

The figure breaks the four-bar model into its logical components. These are

the physical components and abstract entities that you need in order to

represent this system.

Each rigid body subsystem contains SimMechanics blocks that represent

solids and the ir spatia l relations hips˙. The blocks are S olid and Rigid

Transform . The figure shows the blocks that model one of the binary links.

Three Solid blocks represen t the three solid sections of this rigid body—main,

peg, and hole sections. Tw o Rigid Transform blocks represent the fixed spatial
