Hello, I am doing analysis of universal joint assembly (Yoke1, Spider, Yoke2). Spider is a cross member which has 4 bars extruded. So there are 4 revolute joints between trunnion and yokes. Can anybody tell me how to create a revolute joint using RBE2 elements in Radioss Bulk Data? https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQsTSispqWkYwMj6cy6vS8KmDxC2gM9aMmdf_Ffk06VMnPcRNnX To create a revolute joint between 1 bar and 1 yoke hole, I applied the following procedure: 1) Create a center node of the spider bar: node A 2) Create a center node of the yoke hole: node B 3) Create a RBE2 (Independent Node: node A, Dependent nodes: all the nodes on the portion of the bar which will be inside the yoke hole.) 4)Create a RBE2 (Independent Node: node B, Dependent nodes: all the nodes on the yoke hole.) 5) Create a local coordinate system having 'x' axis from node A to node B 6) Assign the node A and node B to local coordinate system. (set reference and set distance) 7) Create RBE2 (Independent Node: node A, Dependent nodes: node B; All dof constrained except dof4 (rotation in x axis) Is this method correct?
Hi sir/Madam, in constraints panel i do not find any option to select local coordinate, how can i constraint only one degree of freedom with respect to local coordinate system ? and what is use of curve option in constraint panel ? Thank you...
Hello, I have Abaqus file that contains material properties (anisotropic). I need to transform the anisotropic stiffness/compliance matrix to be aligned with a local coordinate system which match my experimental test direction. Please see the image below. The values shown in the image are the stiffness along global coordinate system. I need these values along the local coordinate system. What would be the easiest method to do this? Thanks
