Why the angular velocity is not constant?
显示 更早的评论
Greetings
While running my mechanism , I have inputed a constant velocity of 1 rad/s to my motor and then I was watching the velocicities of the other part of the mechanisms.
In order to remove any kind of inertia I put the gravity g to [0 0 0] instead of [0 0 -0.981]
this the velocity profile
But the the velocity of the motor is still not constant
I have also attached the entire mechanism in sismscape
Any hint?
thank you!

You have only configured your motor to have an initial speed of 1 rad/s. To specify that the motor should always move at 1 rad/s, no matter what the load is, you need to feed it an input signal that increases by 1 rad each second.
- Configure the Revolute Joint to accept motion as an input signal and automatically calculate the torque
- Add a Ramp block
- Add a Simulink-PS Converter block
- Connect as shown in the screenshot below.
- Replace Revolute Joint O with this new joint
