    Small DC motor design

    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...

    How to determine weldability of any alloy to 17-7ph

    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...

    What load can change direction during nonlinear analysis ?

    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

    Question about linear guide system structure

    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.

    Question about linear guide system structure

    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...

    Pneumatic system basic calculations

    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...

    Mesh Convergence Study for new boundary conditions

    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...

    Acoustic waves in real life

    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

    Design advice

    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...

    FEMAP API Separate script into different files

    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...

    Standard part searching

    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...

    FEA book

    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...
