Hello everyone,
I am working on small electric motor design and I have some problems.
The main goals are:
Noise level - as quit as possible
Electric consumption - as less as possible
High variance in operational temp -40...100
Operational speed 4000-5000 RPM
I use 2 deep groove ball bearings...
Hello everyone,
I am struggling with something very basic in Ansys. I am trying to make an archive to use it as a back up.
When I try to do it I get next error (see picture below).
I would happy to get any advice how can I fix it or make back ups in other way.
Thanks ))...
Hello everyone,
I have a problem to determine alloys that create good connection to 17-7ph using welding process.
I looked for it in internet and didn't find any table or reference.
As I understand it, it should be some sort of table which define level of weldability between different alloys...
Hello everyone,
what type of load can be used, except pressure , to represent force with direction update due to geometric nonlinearity in non linear analysis?
I didn't find any other option except pressure.
Thanks in advance
Thank you for your answer.
I am totally agree with you and I made same conclusions.
I have already chose the V slide guides.
I have doubts about back structure. Since the range of motion is long, I'm trying to use as less CNC as possible.
Hello everyone,
I have question about best practice in designing of support structure of linear guides system.
I am designing a mechanism with linear motion that is going to work in very contaminated environment under high loads, with almost no requirements to precision and speed.
The idea was...
Hello everyone,
In my next project I need to design pneumatic supply system for a pneumatic device.
It is my first time that I design something like this.
Basically what I need is a guideline to perform first sizing (tube diameters, pressure falls, mass and volume flow rates).
I tried to...
Hello everyone,
I'm working on project where I need to perform linear static analysis.
After modeling process I made mesh convergence study and found stress values.
Now the boundary conditions has been changed.
Do I need repeat mesh convergence study process after boundary conditions changes...
Hello everyone,
I have a project where I need to predict acoustic wave propagation in elastic body.
Do you know some sort of theory and solved theoretical problem that I can start with in this topic?
Thank in advance
Hello everyone,
I design some sort of one direction motion mechanical lock (see attached picture).
The green part leaves free move in X direction and jams otherwise.
It's my first time of this kind of projects.
Did anybody finish something similar to it?
On what should I pay attention?
Thanks in...
Hello everyone,
I'm writing a big script that will help me with my post analysis results routine. I do it on VB.net.
I would like to structure the script and separate function implementation from script code.
FEMAP enables to separate code in different files.
I tried to call function/sub...
Hello everyone,
I'm looking for some sort of standard clamp part. I need it for my next project and I'm not sure it is exist at all.
I need a spherical hinge with some sort of lock that fixes hing in specific position.
I attached picture with thoughts what it looks like.
I really don't want to...
First of all thank you for your list.
The main goal is to build solid background that gives a specific answer in practical creation FEM in the right way.
So If I understand you correct ""Building Better Products with Finite Element Analysis" by Adams" it is the right choice to start.
Other...
Hello everyone,
I'm looking a good book that can help me to add into my background in finite element analysis.
I have few years as stress engineer in aviation field. We use FEMAP as Post/Preprocessor programm.
Basic knowledge in FEA a have got from university course.
I try to watch webinars...
Hello,
I didn't find any information about price level in this field.
Mostly developers offer discuss price in each case separately, depends on details.
It is not an option for me, since I'm going to work on my current employer and I need the specific price.
Any way, thank you for your answer.
Hello ThomasH
thank you for your answer.
The macros, that I will make, are tools for automate routine tasks.
For example, last one is a tool that changes thickness and angle of ply based on special parameters for all layups. Another one is a macro that creates Excel file with MS based on...
Hello everyone, I need advice.
I got a job offer to create VBA tools (scripts and add-ons) for FEMAP.
I'm a stress engineer and I don't really know how much it costs.
I need an approximately price for each tool.
May be someone has an expirience???
Thanks in advance
Hello everyone, I have a question. I just start to work as a stress engineer and found something weird in CBUSH element. Sometimes it gives large forces (BUSH Fx, Fy and Fz) in a simple static analysis. Does it happen with somebody? May be someone knows explanation?
I work with FEMAP and NX...
