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
F | Force transmitted through the spring |
K | Spring rate |
x | Relative displacement (spring deformation) |
xinit | Spring initial displacement (initial deformation); the spring
can be initially compressed (xinit >
0) or stretched (xinit <
0) |
xR,xC | Absolute displacements of terminals R and C, respectively |
v | Relative velocity |
t | Time |
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.
Variables
To set the priority and initial target values for the block variables prior to simulation, use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector). For more information, see Set Priority and Initial Target for Block Variables.
Parameters
- Spring rate
Spring rate. The default value is
1000N/m.
Ports
The block has the following ports:
RMechanical translational conserving port.
CMechanical translational conserving port.
