Translational Backlash

Purpose

Ideal translational backlash

Library

Mechanical / Translational / Components

Description

pict

The Translational Backlash models an ideal symmetrical, two-sided Hard Stop in a translational system, which restricts the relative displacement of the two flanges between an upper and lower limit of   b
± 2  . While the displacement is within the limits, no force is transmitted. When the displacement hits either limit, the flanges become rigidly connected until the transmitted force reverses.

Parameters

Total backlash
The total permitted displacement b   between the flanges, in meters.
Initial displacement
The initial displacement of the flanges, in meters. May be specified in order to provide proper initial conditions if absolute positions are measured anywhere in the system. Otherwise, this parameter can be left blank.

Probe Signals

Torque
The transmitted force flowing from the unmarked to the marked flange, in Newton (N).
Displacement
The displacement of the marked flange with respect to the unmarked flange, in meters (m).
State
The internal state of the component: -1 in lower limit, 0 inside limits, +1 in upper limit.
