Translational Spring

Ideal spring in mechanical translational systems

Library

Mechanical Translational Elements

Description

The Translational Spring block represents an ideal mechanical linear spring, described with the following equations:

where

FForce transmitted through the spring
KSpring rate
xRelative displacement (spring deformation)
xinitSpring initial displacement (initial deformation); the spring can be initially compressed (xinit > 0) or stretched (xinit < 0)
xR,xCAbsolute displacements of terminals R and C, respectively
vRelative velocity
tTime

The block positive direction is from port R to port C. This means that the force is positive if it acts in the direction from R to C.

Dialog Box and Parameters

Parameters Tab

Spring rate

Spring rate. The default value is 1000 N/m.

Variables Tab

Use the Variables tab to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.

Ports

The block has the following ports:

R

Mechanical translational conserving port.

C

Mechanical translational conserving port.
