Translational World (PB)

Global reference frame for position-based translational network

Description

The Translational World (PB) block represents the stationary global reference frame. This block sets absolute zero position and velocity for the connected circuit. All positions in the connected circuit are relative to this reference. All position-based translational ports connected to this block are stationary.

Each position-based translational circuit requires a Translational World (PB) block

The Translational World (PB) block represents a single point in space. Therefore, in most situations it is consistent with the physical view to have only one Translational World (PB) block in a connected circuit.

Examples

Force Flow in the Position-Based Translational Domain

Describes how to interpret forces in a Simscape™ position-based mechanical translational network. The example summarizes rules for interpreting the signs of logged forces and then considers forces in three types of systems: springs being pulled or pushed from different ends, simple systems with external forces applied at a mid-point, and a more complex system with an external force applied at the mid-point.
