Pin constraint inventor Transitional constraint works the best if the constraint loop is simple. Radial - Nodes along the cylindrical surfaces cannot move or deform radially. The only difference between a pin constraint and a "regular" structural constraint is that the pin constraint creates a cylindrical coordinate system on the centerline of the hole, and the constraint directions are in the cylindrical directions of radial (Tr), tangential or hoop (Ttheta), and axial (Tz). Here are the constraints I have planned: - fixed constraint on the top of the piece since it is fixed to the frame - pin constraint on the bolt holes fixing tangential and axial but allowing radial movement (pulling the piece causing shear load on the bolts) - pin constraint on the shackle hole. Frictionless constraint means the object can slide and the face. Nov 12, 2016 ยท The goal is to constrain the pin to ride in the groove in the cylinder that has been made using the emboss feature. It will be simulated in Nastran. This constraint only allow the face to rotate with each other and not moving in any direction, which is true if you only put on 1 bolt. Now in Inventor Pro, all that options are gone! For Pin constraints, you can fix any combination of radial, axial, and tangential directions.
