Closed Chain Kinematics
View transcript
In this example, we're going to put kinematics to a tip dress. First, we need to isolate the tip dress away from the rest of the tool. This we're going to right click on the tip dress, go to the tip dress object and select open in a new app. As you can see, the tip dresses four parts a base, a dresser, a cylinder and a rod. Make sure you're in the kinematics tab at the bottom. Click on Define Kinematics. Click base and click. The anchor just locks it in place. Next, we're going to click the Dresser revolution. Click on the circles of three dots. And here you want to put the three dots on the same plane to show where you want the revolution to take place. Then you're going to click on base and once set, this is a non command joint. Now the base and the dress are tied together. Next, we're going to do the cylinder revolution. Click on Circle with the three dots and again on the same plane. Now we're going to select the base. And again, we want this to be a non command joint. So now the base and the cylinder tied together. So now we're going to do the rod. We're going to select revolution and instead select in the circle the three dots. You can drag the compass put on the edge of the circle, which will snap to the center and then click on Dresser with a non command joint. So now the rod and the dress are tied. So now we're going to do the rod with the prismatic joint, grab the compass, move it to the center of the circle. And here we're going to double click to open up the edit window. Or you can right click the compass and click on edit. The edit window will appear and you can manipulate the compass to any orientation you wish. We're going to spin it around 180 degrees. So the W's facing towards the cylinder where I select the cylinder and we want to select command joint. So now the command joint is what drives this whole tool. We're going to update Save. We're going to go back to the main tool, right click on mechanism manager, the assembly tab and put a mark in that square and click okay. So now when we click the jog button, we can move the tip dress. You can slide the bar left and right to move it so or you can type in a value. So it will say 280 millimeters and it snaps to 280 millimeters inside the cylinder because that's our driving force. We'll hit zero to push it back out. And now we have a working tip dress.
