    Roughness measurement contact

    Hello everybody, My question concerns contact roughness measurement. I have a talysurf in my laboratory. I would like to measure roughness on the polycarbonatre surface. It's destrying the surface, and I would like know if it is possible to estimate the wear induced by the talysurf to...

    FFT Filter

    Hello everybody, I am trying to look at the FFT of a sound signal. I used for it scilab. The problem I have is that there is a lot of noise, and I do not know how to remove it. What kind of filter should I use? Please answer simply, I am not used to signal treatment analyzis! thank you mereaux

    Working alone

    Thank you for your advice! The last weeks I tried to encourage more people to have interest in what I am doing. I get more contacts like this and it make me life better. I go every time to people who know the process. It is not really a team, but I think with perseverance I can get one... At...

    Working alone

    Hi everybody, I work since 7 months and I am doing research on a very interesting subject to me. Most of the time I am working alone (I do research in a production place, where mostly people are product/process engineers). It is my first experience, I am in a foreign country, I am not real...

    Motor for lead screw

    Hello everybody, One of my projects conducts me to the use of lead screw, to travel an object above a surface. This device is quite small, as small as the laser device of a CD player. I wanted to use the travelling system of a CD/DVD player, however I do not get the information I need. I am...

    Evaporation rate

    OWG, Thank you very much for your quick answer! What do you mean by correlation? Do you know such correlation available for all solvent? Could you explain me it? thank you. Mereaux

    Evaporation rate

    Hello Everybody, I am working on powder deposition with a solvent which evaporates. I have to change the actual solvent by another, which evaporates slower. I have datasheets of the two solvents, it is indicated the evaporation rate and also a reference BUOAC=1. I do not understand what it...

    Powder behavior simulation

    Hi everybody, I am working on a cartridge and I would like to make a simulation of the behavior of toner pushed by a rubber bar on a turning cylinder. Does anybody know software about it? Thank you very much in advance, Mereaux

    MFI and viscosity

    Hi everybody! I would like to know if there is any relation between melt flow index and viscosity. I know when the MFI increases the viscosity decreases, but is there any precise relation between these 2 measurements? thanks Mereaux

    Contacts observation

    Hi everybody I tried those films, but it is not precize enough in spite of the fact I hav emore information about the pressure between my rubbers. any other idea? Mereaux

    Kinematic Coupling

    Hello everybody, Could someone explain to me, what is the kinematic coupling in abaqus. I have read the user manual. But I do not understand what is the function of the reference point? Should this reference point have boundaries conditions? What happen then to the coupling nodes? thank you!

    Microscopic scale

    I am looking on contact surface, by simulation and experiments... contact between rubbers. I would like at least to make approximation by theoritical calculation, that is why I need such information on mechanical properties at a microscopic scale. And I don't know what are the theory on this...

    Microscopic scale

    Hi everybody! Do somebody know here any theory about mechanical properties of materials (plastic, rubbers) at a microscopic scale. Is there any apporximation? Thank a lot for answer. Mereaux

    "ANSWER Express" CFD Package by ACRi - Any Comments?

    Hi JulianHardy, I would like to know if you are satisfied of this software now? Is it easy to use? What can this software simulate, I see the wwebsite but I dont understand ? Thank you for you answer!

    Powderviscosity

    hi! Do you know how we can measure the viscosity of powder? Does it exist a model to describe the viscosity of powder when it does not flow? thank you mereaux

    Contacts observation

    I try to be more precise: My system acts like a sweeper, the rubbers are always in contact to remove particles. And the contact pressure is a crucial parameter for this. But the rubbers present a wear/roughness during aging, and the system can not be so efficient. I cannot use a filter in the...

    Contacts observation

    I need a fine accurancy because I need to know if Particles whose size is about some microns (5-10microns)can go between these 2 Rubbers. For this problem I need to have a look at the wear/Roughness of the Rubbers. The film that you speak about, can perhaps permit me to understand if one rubber...

    Contacts observation

    It seems to be a real interesting tool! Do you know if it is easy to read and if we can have a very fine pressure distribution over the length (in the order of few microns)?

    Contacts observation

    Hi everybody, I am working on contact problem between rubbers, I have difficulties to observe the contact (only some microns width and over the length more than 30cm). Does anybody know methods to measure contact of difficult accessible part? I mean like a moulding method?? thanks for your...

    Rubber contacts

    hello New user of Abaqus, i am working on rubbers contacts, and would like to use Abaqus to understand contact pressure, crack propagation, and make wear prediction. WOuld you give me some tips? Thanks
