    Modeling of Clevis Pin Connection

    I figured I would bump this question as I'm looking into this part again. The method I intend to use now is to work out the reaction force at the 2-force member using a FBD, and applying that directly to the model (i.e. removing the dummy link from the study). I'll have to apply a rotational...

    Modeling of Clevis Pin Connection

    Hi all, I am trying to model a connection between a clevis-type two-force member (a placeholder for a tensioner-type part) and a bearing mount: http://i.imgur.com/otzNHoX.png I already have a model of the part running with pin constraints at the mounting points, without the clevis part, but I...

    Sheetmetal - Butted 2-Bend Corner

    Hi all, I would like to use the Closed Corner feature on the highlighted corner (I would describe it as a butted corner); unfortunately NX won't seem to let me. I could manually extend the end of the bent flange to go meet the top sheet, but I want to get the nice V-Cutout in the corner.

    Epoxy as locating adhesive

    Hi, I am using Loctite Hysol E-20HP to bond a small aluminum piece to an organic-based substrate (optical application). My intent is to very precisely locate the aluminium part: basically I hold the part in place using a jig, after lining it up optically, while the epoxy cures. My question is...

    Boundary Lubricating in Low-Pressure Application

    The application is a silicone chip resting on a substrate, wetted by a layer of antioxidant flux (before soldering of the contacts); I'm coming up with a rough model of its resistance to displacing disturbances. I would suppose near-atmospheric pressure, probably regulated by capillary forces...

    Boundary Lubricating in Low-Pressure Application

    Thanks for the tip. I can assure you I've been searching the web for a few hours now, I only use forums as a last resort... What I guess I'm really searching for is a theoretical explanation as to what makes a wet surface slippery. I don't know if boundary lubrication is the proper term...

    Boundary Lubricating in Low-Pressure Application

    Hi, I'm trying to find theoretical documentation or insight relating to boundary lubrication in a low-pressure application. I'm trying to model the static friction in a system consisting of metal-to-metal contact, wetted by a (somewhat viscous) fluid (sorry I can't disclose the specifics). The...
