How to connect DC motor output to a prismatic joint ?

I have a linear actuator that I designed for my project.

Basically two parts connected with prismatic joint.

How can I give input to that system with a DC motor ? The system I tried giving me the error below

Hello Fatih,

I think you can use the Translational Multibody Interface block available in Simscape to connect the output of a DC motor to a prismatic joint in MATLAB Simulink.

This block facilitates the connection between Simscape mechanical networks and Simscape Multibody joints, such as a prismatic joint.

refer to this similar MATLAB Answer post and MathWorks documentation links which can be helpful

Hope this information helps you in moving forward

Hello,

This suggestion helped me a lot. I am able to create a force output but it is 0 :(.

As I saw from the other examples, the C output of the interface supposed to be connected with mechanical referance. My system doesn`t allow me to do that I don`t understand why.

Do you have any suggestions about it ?

Allright, I have solved by myself :) The referance supposed to be Mechanical Translational Reference to connect with the the Translational Multibody Interface. Adding here as a note
