Working with Joint PrimitivesA joint primitive places a restriction on relative motion, such as restricting one part to always move parallel to another part. The joint primitives do not have physical counterparts as the idealized joints do. You can, however, combine joint primitives to define a complex constraint that cannot be modeled using the idealized joints. Table 2.5 lists the different types of joint primitives that are available in ADAMS/View. Table1 2.5 Joint Primitives in ADAMS/View
To create a joint primitive: 1) From the Jointpalette, select the joint primitive tool representing the joint that you want to create. 2) In the settings container, specify the following: How you want the joint connected to parts. You can select the following: 1 Location - Bodies implicit- Lets you select the location of the joint and have ADAMS/View determine the two parts that should be connected. ADAMS/View selects the parts closest to the joint location. If there is only one part near the joint, ADAMS/View connects the joint to that part and ground. 2 Bodies - 1 Location- Lets you explicitly select the two parts to be connected by the joint and the location of the joint. 2 Bodies - 2 Locations- Lets you explicitly select the two parts to be connected by the joint and the location of the joint on each part. You should use this option if you are working in exploded view. How you want the joint oriented. You can select: Normal to Grid- Lets you orient the joint along the current working grid, if it is displayed, or normal to the screen. Pick Geometry Feature- Lets you orient the joint along a direction vector on a feature in your model, such as the face of a part. 3) If you selected to explicitly select the parts to be connected, select each part in your model using the left mouse button. 4) Place the cursor where you want the joint to be located, and click the left mouse button. If you selected to specify its location on each part, place the cursor on the second location and click the left mouse button. 5) If you selected to orient the joint along a direction vector on a feature, move the cursor around in your model to display an arrow representing the direction along a feature where you want the joint oriented. When the direction vector represents the correct orientation, click the left mouse button. ADAMS/View creates the joint at the specified location. Date: 2015-12-18; view: 4914
