Translational Spring - Simulate ideal spring in mechanical translational systems

Mechanical Translational Elements

Description

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

where

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

Spring rate

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

Initial deformation

Spring initial deformation, or offset, in length units. The deformation is determined as x = x_init + x_R – x_C, where x_init is the initial deformation, andx_R, x_C are the absolute displacements of terminals R and C in the globally assigned positive direction. The spring can be initially compressed (x_init > 0) or stretched (x_init < 0). This parameter specifies the initial condition for use in computing the block's initial state at the beginning of a simulation run. For more information, see Computing Initial Conditions. The default value is 0.

Ports

The block has the following ports:

R

Mechanical translational conserving port.

C

Mechanical translational conserving port.
