    Radial O-Ring seal Gland chamfer

    Ive actually been refferring to the Parker handbook but I cant find sufficent info regarding chamfer leading edges. I must have skipped over it. Ill go back and get digging. Thanks both

    Radial O-Ring seal Gland chamfer

    Hi all, I have a radial o-ring seal (4mm Cross section, 13mm ID)and I am looking for some literature regarding the leading edge chamfer dimension to aid in o-ring assembly/insertion. I have tried a couple of places but I cant seem to find any solid literature on the subject. From what I have...

    PTFE NPT Plugs - Are they ideal?

    I have been working on a design that features a fluid manifold made from A standard grade PTFE (temp increase up to 200C). my intention was to use a plug (which will act effectivly as a blacking plug) as I need to seal off the area. To keep expansion rates the same, i was going to use to same...

    Definition of NACA Duct Help

    Thanks for the input Greg, Im happy with the x and y coordinates. My concern is the depth z profile) the part that i have and that has been 3 scanned appears to be considerably deeper than most naca duct profiles.

    Or should I be aiming for something with a sweep more like this?https://files.engineering.com/getfile.aspx?folder=fe402e1e-e6b4-4c63-9a82-5473f800971d&file=NACA8.PNG

    Definition of NACA Duct Help

    Hi all, just looking for some help and advice on a NACA duct that i modelling up on CAD. I am in the process of building a closed-wheel time-attack race car, I had a NACA duct intake that feeds air directly into the radiators and oil coolers. Unfortunately the carbon fibre moulded NACA duct I...

    Simulating true weight on Explicit Analysis

    I thought that was the case. I'll have a go with 19.0 later on tonight.

    Simulating true weight on Explicit Analysis

    thanks for the response FEA way, I vaugly remember looking into this a while back for i sepoerate reason. I have a feeling that you cannot add point a mass on my version of Ansys (17.0) but I do have access to the student version. I will look into it. Thanks again.

    Simulating true weight on Explicit Analysis

    Hello all, I am currently analysing the crash deformation and structual strength of a tubular space frame chassis. The chassis weight is around 130kg, I have no issue with my current set up simulation. However this result is unrealistic. the final weight of the car (engine, gearbox, driver...

    Determining plasticity parameters of AISI 4130 Steel

    Hi, I hope that someone can help me. I am currently investigating the crash deformation of a tubular space frame chassis on Ansys (Explicit Dynamics) Ansys has a number of preset Explicit Dynamic Materials that define the characteristics required to help model the material requirements for use...

    Help Understanding and defining required plasticity parameters of aisi 3140 Steel

    Hello, I am analysing a tubular-frame chassis collision using the explicit dynamics solver on Ansys. I have sufficient data regardign the 3140 steel properties as you would expect. However I want to explore the deformation and I want to allow the structure to deform to try and give a best...

    Chassis model seperating under explicit Dyanamic simulation, how to bond parts together

    Thanks for this FEA way, this seems like a good soultion also as at least i know the geometry will be sufficient for use within the explicit solver (better that importing geometry from an external model at least. I had a quick attempt at inmporting the sketch by means of a Step file but it did...

    Chassis model seperating under explicit Dyanamic simulation, how to bond parts together

    Thanks for your input both, I am a new user to Abaqus so there is obviously a lot I am yet to learn. FEA Way - Im assuming that there is a beam profile feature on Abaqus yes? The reason, my worry is that I would not be able to import my 3d sketch from Solidworks to use as a reference, I would...

    Chassis model seperating under explicit Dyanamic simulation, how to bond parts together

    Thank you for the advice. I will attempt to resolve this issue and get back to you.

    Chassis model seperating under explicit Dyanamic simulation, how to bond parts together

    Thanks for the advice, the chassis I have imported has been imported as once whole part as opposed to separate sections (which is why this is throwing me off) I have tried the tie constrain as you suggested but I have no luck, I have simplified the chassis structure for the moment and have only...

    Chassis model seperating under explicit Dyanamic simulation, how to bond parts together

    Hello, I want to analyse a the deformation of tubular space frame chassis on Abaqus under a crash scenario using explicit dynamics. I have created the model on Solidworks using the weldment feature and imported the part into Abaqus as a parasolid file. however upon completion of the run it...
