    Rotating shaft

    No need to reply to this thread, I held the aprropriate contact point in UY direction only which allowed for rotation in the UZ and obtained satisfactory results. Buggles

    Rotating shaft

    Hi, I've modelled a shaft with bearings using an equivalent density to simulate the mass of a 24 tonne rotor. I used SOLID187 elements throughout, and the contact manager for rotation at the bearings; TARGE170 for the rigid bearings; and CONTA174 for the rotating shaft. The shaft is to rotate...

    Pressure drop in a large industrial motor

    Hi, I'm trying to work out the pressure drop in a 4778kW, 4kV, 60Hz, industrial motor. The airflow/cooling air is generated by the motor through the vent spacers. There are 8 inlet air vents of 135000mm^2 each with a minimum steel mesh area of 45% on each mesh. 4 at each side of the motor...

    beam loads

    Check out the following link for an example of applying a constant load on a beam. You can also apply a linearly increasing load as per your example. Check out the ANSYS help menu, it's generally quite good. http://www.mece.ualberta.ca/tutorials/ansys/IT/Distributed/Distributed.html

    Piping Analysis

    Hi, ANSYS has a very good capability for analysing piping systems. Personally, I've had limited use in the area. If you model your pipe using areas and apply shell elements with a thickness, this should help to keep your model size down to a minimum.

    Simulating bolted joint using ANSYS Workbench

    Hi, I'm trying to simulate the effects of a bolted joint withstanding a pressure of 15000psi using workbench. Here are the details: I have an 12mmthick annular ring, 70mm ID, 130mmOD which is held by 6 off M8 bolts which are counter bored into the annular ring at 6mm deep. The counterbore...

    Contact elements

    I answered it myself, well thanks to the friction post I read from 'stringmaker'. I overcomplicated things by putting a co-efficient of friction into my model.

    Contact elements

    Hi, I'm trying to simulate a bolted joint using contact elements in a larger model so I'm trying to model a single bolt independently to begin with. I've created the joint structure using volumes and meshed the contact and target surfaces using TARGE170 and CONTA174 respectively. The normals...

    Underconstrained model with BEAM44 and SHELL63

    Thanks dude, yes it was a pretty basic problem! I had to attach BEAM44 elements in the Z plane to the middle of SHELL63 plates in the xy plane but I never divided up the plates to create keypoints to which I could attach the beams. Buggles

    Underconstrained model with BEAM44 and SHELL63

    HI, I'm analysing a frame where the members are beams BEAM44 and the flat plates are areas SHELL63 at right angles to the beams. i.e. one plate either side of the beams holding the plates together I'm holding the keypoints in all DOF for the beams where they meet the flat surface area of the...
