Ideal spring in mechanical translational systems
The Translational Spring block represents an ideal mechanical linear spring, described with the following equations:
|F||Force transmitted through the spring|
|x||Relative displacement (spring deformation)|
|xinit||Spring initial displacement (spring offset)|
|xR,xC||Absolute displacements of terminals R and C, respectively|
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.
Spring rate. The default value is 1000 N/m.
Spring initial deformation, or offset, in length units. The deformation is determined as x = xinit + xR – xC, where xinit is the initial deformation, andxR, xC are the absolute displacements of terminals R and C in the globally assigned positive direction. The spring can be initially compressed (xinit > 0) or stretched (xinit < 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 Initial Conditions Computation. The default value is 0.
The block has the following ports:
