Simulink model for Differential equation

Hey, maybe someone can help me. I have to create a Simulink model for the following differential equation:

I have already solved the equation for xdd

.

The equation looks very similar to that of a "mass spring damper" system.

I already know how the model looks for that system (look below). I just need some help modifying it.

Thank you for the help

Hi, can you give some more information on what you need help with? If you can share the model you are working on, and give some informaton on your difficulties, we may better able to help.

i just need some help representing the equation above in a simulink model. It should be pretty easy.

The force F is the input into the system. But you used sinewave model for the force. Follow the attached sketch. Make sure you used the sinewave block ans set the values. You must set the input force

Let me know if it is working

[TwiceYTPL]

yes it works very fine. Thank you for the great help!!!

Your simulink model seems correct. Can you be exact regarding your request?

My model is for the equation

I need some help modifying it to the equation

I have to implement the sinus, somehow. I just dont know how

Thank You
