You will see how SimMechanics features build upon standard Simulink features to model a mechanical system. The demo model simulates a conveyor belt loading mechanism. A simple controller (not shown), with a sensor and an actuator, guides the mechanism with a saturation limit and anti-windup logic for the applied torque. You can adjust the controller and set the stopping point for the pusher. Conveyor Loader Mechanism Viewing a Mechanical Drawing of the Conveyor Click here to open a detailed mechanical drawing of the conveyor. What the Demo Illustrates The conveyor mechanism demo illustrates some important SimMechanics features: Representing bodies and degrees of freedom with Body and Joint blocks, respectively Using SimMechanics blocks with normal Simulink blocks Feeding Simulink signals to and from SimMechanics blocks with Actuator and Sensor blocks, respectively Encapsulating groups of blocks into subsystems Visualizing and animating a mechanism by its component bodies Caution You might want to make modifications to this demo model. To avoid errors, Do not attempt to connect Simulink signal lines directly to SimMechanics blocks other than Actuators and Sensors. Keep the collocation of the Body coordinate system origins on either side of each assembled Joint to within assembly tolerances. Saving modified demo models in a different folder from the demos is recommended. Opening the Model To get started quickly with the conveyor demo model, follow either of these steps: Enter mech_conveyor at the MATLAB command line. If you are work
