    Axial + Hinge Connectors / Displacement Issues

    Hello, I'm trying to simulate a mechanism on which I have two movements as follows: 1. Linear Movement in U1 through an Axial Connector. 2. Angular Movement in U1 through a Hinge Connector. Steps Step 1 ------------------- Movement 1. -3 inches- Step 2 ------------------- Movement 2...

    Pvc Pipe Local Buckling due Internal Pressure

    Hi Gents, I’m machinery designer for the PVC pipe Industry, at the very beginning of this year I designed and built a Machinery to test PVC pressure pipe according to AWWAC900/05 and (or) FM Standards. My customer is request me, and special test called Burst -the pressure rate depends on the...

    4C900 PVC Pipe Buckling during Testing

    Hi Gents, I’m a machinery designer for the PVC Pipe Industry, few months ago I was involved to design a Hydrostatic Pipe Tester according to AWWA C900/5 or FM Standard. One of the special features requested by my customer was “Quick-Burst” capability using a whole pipe -6.1m / 20ft long- as a...

    TRANSIENT PIPE COOLING FEA

    Dear All, I need to figure out how can I set up this FEA, I wanna simulate a plastic pipe cooling process in a extrusion line, so basically, I have a water cooling nozzles over the surface of the pipe, they're fixed in a frame, and the pipe goes in a constant velocity passing for all the water...

    Steady state heating pipe + Transient cooling

    Hi guys, Im stucked trying to model a very simple FEA, I need to heat up a pvc pipe applying air convection load, to find time needed to. I did and steady state axisymetric model, and apply a Surface Film and initial temperature by a predefined condition, but looks like the temperature never...

    Huge Deformation on Sharp Indentation

    Dear All, Im trying to get the force needed to penetrate a PP (elasto-plastic) tube with a sharp tooth -rigid surface-, using ALE, but cant get results,instead I get huge mesh distortion. Anny suggestions? Regards LPUS...

    Wrapping Steel tube with Carbon Fiber laminates

    Dear All, This is my first approach to model a steel tube-like wrapped with carbon fiber laminates, exactly I don't know how can I orient the fiber layups into cylindrical coordinated system, what are the steps I need to consider, and how I tied between steel and carbon fiber. Apologize me if...

    *SYMMETRIC RESULTS TRANSFER

    Hi, I'm running axisymetric contact analysis, 3 deformable parts, one of them hyperelastic, but right now i wanna transfer the results into another 3d new analyis to apply non axisymetric loads. I know that abaqus manual says, thats no possible to transfer results from assembly instances...

    Clip-spring insertion

    Dear friends, I’m trying to do very basics, insertion analysis of a ring in to a shaft groove, via prescribed displacement conditions to know the force required, but until the ring reaches the grove the job is aborted by a classic convergence problem, “ Time increment required is less than the...

    DMTA and Prony Series

    Hello all, Modelling a pipe-end socket thermoforming-like simulation of PVC I been found a lot of problems, exactly that I try to do is this: http://www.youtube.com/watch?v=vDW4tSda_0U I have DMTA test results E' and E'' against time and temperature sweep. The question is how EXACTLY do I...

    thermoforming of a PVC pipe socket

    Good Morning Dear team. Right now I’m experiencing troubles with an FEA Abaqus analysis about the thermoforming of a PVC pipe socket. Let me try to explain you in detail: The Rieber socket forming system enables thermoforming of sockets with integrated gaskets. Rieber elastomeric gaskets are...

    Globoidal Cam Design

    Hi Guys, I just started with a new project about cam indexer design, but don´t have much information about how the design the "wedge profile", maybe somebody can help me with their experience, I´m designing the cam profile on Pro/Engineer, but I don´t understand too much how this modified...
