    Acceptable porosity severity level for sealing surfaces in compressors

    Hello fellow engineers, I am presently working on defining the porosity severity level for sealing surfaces in screw compressors. We have received few reclamations for a component(air regulator) as there was a leak in the sealing. The major cause for this was the pores in the component. We...

    Thermal expansion co-efficient of EN-AC-AlSi7Mg0.3 ST6 at -40 deg C ?

    Hello every one, My question deals with a project replacing a cast iron housing (EN-GJL 250) with aluminium cast (EN-AC-AlSi7Mg0.3 ST6) housing. I am calculating the fit geometries for the new material housing based on its material thermal expansion properties. The housing has extreme...

    Break away torque calculation of lock nut against rotating/acceleating bolts?

    I have a Scenario where my lock nut is tightend using a prevailing torque of 14 Nm (as mentioned by the manufacturer) on to the rotor placed between bearings (But the tightening direction and the rotor rotating direction is same unfortunately). The lock nut is loosened after particular life...

    FSI co-simulation of a revolute joint

    Hello everyone, I have simulated a structural revolute joint in Abaqus which contains a bush revolving over the pin. When pretension applied, the pin creates about 290 Mpa contact pressure(CPRESS). Now, I want to introduce an oil film beneath the bush and apply this pressure on the fluid and...

    FSI co-simulation, Abaqus

    How can I choose a perfect solver for my FSI simulation? I have tried a couple of solvers in Abaqus but had no luck. I am trying to find the contact stresses in a bushing co-simulated with an extremely thin motor oil film but had no luck converging my solution. Any suggestions? and any...

    x-momentum not converged; co-simulation

    Hello guys, I am trying to simulate an FSI with an oil film in between chain joint using Abaqus Co-simulation. I was able to successfully simulate the structure step 1: pretention with 20N concentrated load. step2: rotation on 30rad/sec with 240 N load on the bushing. The oil film is present...

    Co-simulation error

    hello all, I have modeled a Fluid domain to conduct FSI simulation. In the co-execution, I had momentum convergence and the element deformation errors. To rectify this, I edited the keywords of the Fluid domain to include FSI controls. After the data check Abaqus CFD aborts with the error...

    Rotation of a part after deformation

    Hello Guys, I am presently working on Abaqus to analyze contact and pressure on a revolute joint(hollow cylinder-bushing over a solid cylinder-pin) when it is subjected to dynamic loads. 1.The pin is attached to the pin plate with a surface-surface explicit hard contact interaction and so is...
