    Random vibe analysis bolt reaction (ANSYS workbench)

    Good day, Is there any way to export the reaction loads of a random vibe analysis to a static analysis? We currently have the task to asses if the bolts we selected for a bolted vibe fixture test will withstand the loads during a random vibe analysis. We are using ANSYS workbench, we already...

    ASME piping code

    Good day, I am currently looking to take a course into ASME piping design. In your experience, what piping design course do you recommend me to take? I will be working with pipe lines transporting dry air at hot temperatures, so I am interested in learning: -Considerations for supports. (fix...

    Braided flex hose maximum allowable air velocity

    Thanks for the reply LittleInch, This is for an engine exhaust testing. Talking to a peer, he mentioned that a rule of thumb up is to not exceed 0.3 Mach. I checked the Mach number for this application and we will be around .2. Most braided flex hose providers mention that above 150 ft/s is...

    Braided flex hose maximum allowable air velocity

    Thanks GregLocock, Regarding the reference info, is that they know the same type of flex hoses have work with air flow at 280 ft/s. Regards, P.P.

    Braided flex hose maximum allowable air velocity

    Good day, I was recently working with a 6in flex hose component (as shown in the link), it will work with compressed air at 650F, 80psig and a flow of 380 ft/s. https://www.metraflex.com/product_cat/flexible-metal-hose/ I read that when the air flows over 150 ft/s, they place an inner liner...

    Flex hose with interlock liner max inner air flow

    Good day, I was recently working with a 6in flex hose component (as shown in the link), it will work with compressed air at 650F, 80psig and a flow of 380 ft/s. https://www.metraflex.com/product_cat/flexible-metal-hose/ I read that when the air flows over 150 ft/s, they place an inner liner...

    ASME Pipe recommended courses

    Thanks MJCronin, Yes, I would like to perform a stress analysis to compare it against the code allowable. The thing here is that my company only counts with ANSYS, I was trying to find a way to perform it in there. Regards, P.

    ASME pipe check V1

    Good day, Do you know if "ASME pipe check V1" app works with ANSYS 2020 R1? I have tried to use it but it keeps plotting zero of stress. Regards, P.P.

    ASME Pipe recommended courses

    Good day, I would like to learn how to use ASME B31.1 to validate a pipe line. Regularly, what I have done is perform a simple FEA analysis on ANSYS with pipe elements (beam) and compare the ¨maximum combined stress¨ obtained from the ANSYS stress results and compare it against the allowable...

    ASME B31.1 types of stresses

    Good day, I just started researching about how to validate a pipe line using ASME B31.1. But I have a couple of questions regarding how to compare those stresses with the allowable stress. I see that there are 3 types of stresses: Sustained, displacement and occasional, I am trying to use FEA...

    ASME code

    Good day, I was interested on taking a course with ASME to learn how to design and validate a pipe line. But I wonder which ASME standard applies for the application of piping that I will design. I will validate stainless steel pipe lines that conduct air at pressures around 300psig and...

    perforated plate modeling as porous domain ANSYS CFX

    Good day, I am currently developing a pressure drop analysis in a pipe, I need to simulate the effect of a perforated plate inside the pipe. I know the opening area of this perforated plate. I am familiar modeling orifice plate and perform a quick steady analysis. But this time, modeling the...

    Impulse load assessment

    Thanks for the response! Is there any reference sources you can share? I would like to learn more about it. We are basically going to analyze a rectangular flat wall. I was researching about the ansys tools, and I found that an explicit analysis suits better for forces acting in less of 1...

    Is there any advantage buying screws from McMasters vs from Home Depot and Amazon?

    One advantage of buying on mcmaster is that you have spec data information there (tensile strength, hardness etc). Also you can download the step model and include it into your CAD.

    Impulse load assessment

    Good day, I wonder how impulse loads are considered during a mechanical validation of a structure. In this case, we need to design a structure based on some impulse loads that we received from our peers. These loads are high from .0001 seconds to .01 seconds after this time they got to zero. I...

    ANSYS CFX multi domain modeling

    Good day, I am trying to model a bubble decompression inside a tank. This tank is half full with water and the other half is air. I have some questions regarding the set up of this problem. The intention of the bubble has an initial pressure of 50psig and then it drops to 0 psig at 0.1 seconds...

    Water tank reactions

    Is there a way to model a bubble in CFX ANSYS? I am using ANSYS R1.I have performed pressure drop analysis on pipelines and manifolds. But not familiar with a bubble. If you have any reference source in where I can research more about, I can take a deeper look. Regards, P.P.

    Water tank reactions

    Good day, it is a horizontal cylindrical tank, the door is one of the caps. it has a vent area on the top of the tank. Regarding the failure method, most of the cases is that one of the welded edges fails. But I believe I would like to model the worst case, which I believe will be 1) from your...
