To Add Modeling Entities for Mechanism Dynamics
After you create your mechanism and make sure the connections allow it to move correctly, you can add any of the following modeling entities:
• Servo Motors—Use servo motors in Mechanism Dynamics when you know the relative motion of two bodies. You can also use servo motors to help you to determine the properties of a force motor that produces equivalent motion in your mechanism.
• Force Motors—Use force motors when you know how much force to apply to make your mechanism move.
• Springs—Use a spring to provide forces proportional to stretching. You can apply a spring to a motion axis or between two points.
• Dampers—Use a damper to remove energy from your mechanism's motion. A damper acts to slow down motion. You can apply a damper to a motion axis, to a slot-follower connection, or between two points.
• Force or Torque Loads—Use a force to act on a point in a specified direction, or a torque to act on a body. You can also define a point-to-point force. You can define the direction of forces and torques relative to ground or relative to the body to which the force or torque is applied.
• Gravity—Define an acceleration vector to simulate gravitational force acting on the entire mechanism in a specified direction.
• 3D Contact—Define the contact between a pair of selected surfaces (from two different bodies) when there is contact between points or lines.
• Belt and Pulley system—Define a pulley to change the direction of an applied force, to transmit rotational motion, or, if the pulleys are of a different diameter, to increase or decrease the force along a linear or a rotational motion axis
