Thread lube, including thread locker (wet torque), reduces friction
Loctite's literature states that their thread lock products act as a lubricant but I did a training course on bolted joints 2 years ago and the very knowledgeable instructor was adamant that this is not the case, based on my...
Blake,
I work with a powertrain design & development consultancy and have designed several optical engines for use researching combustion process fundamentals. Our optical solution overcomes the issues you describe with the hemispherical combustion chambers and has been used successfully for...
It depends what you want to do with the resulting STEP file.
If you want to simply get a STEP file that is an exact representation of the STL file's elements, ProE allows you to open the STL then save it as a STEP but the file size can be large and it still features all of the little triangles...
Thanks for all of the replies.
Mike, I've purchased a copy of the book you suggested and its fairly interesting but a little vague on design limits. The way the old timers laid out equations is very different to what is taught nowadays (well, relatively recently anyway).
Question for Greg...
I've been handed a design job that involves designing the cranktrain for a crosshead engine (think large ship engine type arrangement).
The one area of this where I have no previous experience is designing the crosshead & slide mechanism so I'm hoping that someone might be able to point me in...
BrianBT,
I'm very interested in your comment about ring wear measuring equipment on large, slow speed engines (I'll assume you mean very large ship engines). I'm about to start working on the design of my first engine of this type (all my previous experience is with automotive and off-highway...
I am generating concept models and periodically I need to generate different versions of a sub-assembly as I explore different design ideas.
I am using Wavelink to link several key geometry features between the different components within each sub-assembly (there is one central part where the...
The purge function works under low load conditions when the throttle is closed and there is sufficient vacuum to pull the contents of the canister into the manifold.
This can be a problem for highly boosted/downsized engines that don't spend as much time with low manifold pressures compared to...
I am about to start a project designing & modelling a new intake port for an engine using NX7.5.
Most of my CAD experience is with ProE, I have some NX expereince but this is limited to much simpler polygon based geometry so I am after some advise from anyone who has experience of this type of...
Thanks for the responses everybody.
Romke, we've still got some work to do but hopefully the fuel and coolant will be ok, it helps me that there is a reasonable amout of data on the properties of these fluids at low temps but I'm struggling to find any data on the oil at extremely low temps as...
I'm involved in a project where we will be running a gasoline engine in a very cold environment, think -60degF/-50degC or colder.
Please ignore all the usual issues of getting the engine started, it will be started and warmed up in a warmer environment and while the engine is running the oil...
I'm don't know exactly how the application files for our CAD installations are set up, some configuration files are pulled from a server drive but I don't know if all of the NX application is loaded like this.
I will attempt to get the IT department engaged with this issue tomorrow.
Thanks.
