Hi everyone,
i'm trying to verify if a dc motor+transmission system is suitable for an application and if the force that is actuated is enough.
To be precise enough what could be the suitable way to verify if the force is enough? the first problem is the simulation of the load, that is a load that increase up to 200 N in a space of 3 mm and reched this peak, goes down quite vertically.
Do you some advice for me? i'm quite a beginner with matlab and simscape, so i hope to get some advices.
Thanks in advance.

It would be better if you can give a detailed explaination of your problem statement. Also, if possible share your simulation model.

I share with you the model.
Now, the target of my simulation is to verify if an actuator, dc motor+transmission system, is able to apply a force of 500N. In my idea, the load has been simulated using a spring, and my necessity is to verify if the motor is suitable for my application in terms of force applied, torque and current absorption.
I am a mechanical engineer, so for what concern the electronic part, now is not about me, so the control part of the motor is not so important in this phase.
Do you think my model is adapt for it?
I'm trying to get better with simscape, so i need some advices.
Thanks in advance.

I think all you need to add is a force sensor to see how much force your actuator is delivering.
I have attached an updated model, and you can see how to add the sensor in the screenshot below.
