Translational Free End

Translational port terminator with zero force

  • Library:
  • Simscape / Foundation Library / Mechanical / Translational Elements

  • Translational Free End block


The Translational Free End block represents a mechanical translational port that moves freely, without force.

You can use this block to terminate mechanical translational ports on other blocks that you want to leave unconnected. This is not necessary because if you leave a conserving port unconnected, the physical network sets all the Through variables at that port to 0. However, terminator blocks improve diagram readability.

You can also use this block to set the initial translational velocity at a node.


To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables.
