USAGE OF FORCE AND TORQUE

 

With the Force/Torque tool in mechanism, you can introduce external forces or torques into your model that are not due to impact or forces caused by servo/force motors.

 

When you apply a force/torque, you have three different options:

·            Point Force – The force is applied to a datum point on a body, at a specified magnitude and direction.

·            Body Torque – The torque is applied at the center of mass on a specified body.  The magnitude and direction of torque is then specified.

·            Point to Point Force – The force is applied equally and opposite two selected points.  If the two points are coincident, the value is zero.

 

For the magnitude of the force/torque, you have additional options for how you specify it:

·            Constant – A constant force is applied to the object.

·            Table – Use a table to define force as a function of time.

·            User Defined – Create your own function to define the force using an equation editor.

·            Custom Load – Write special programs to define your forces.  This is not standard out-of-the-box functionality, and will not be covered in this course.
