Hello All,
I am investigating the safety factor for a keyed shaft under constant torsion and reversed bending, but questions keep coming up:
Our keyways are machined using an end mill, which produces a very sharp radius at the fillet. I know there is no such thing as a zero radius, but this is...
Hello All - I have been searching for the endurance limit of 1045 cold-drawn steel bar but have thus far been unsuccessful. Does anyone know where I can search or have a source I could reference to get this value? Thank you.
Hello All,
I was hoping someone could shed some light on the effects of a single square keyway on a solid shaft that experiences steady torque and a reversed bending moment, such as a pulley shaft. In my engineering books I have not found any mention of accounting for keyways, only changes...
Is it possible to replace the watermark in ANSYS v15.0 workbench with something more personalized? I know in previous versions this was possible as explained below:
There is a file in the installation folder called ANSYS_150.png that contains the watermark image used in DM, Mechanical, Meshing...
Hello All,
In my quest to determine the most appropriate method of static weld analysis with FEA I have come across at least a half dozen methods. All of these seem to have their own merits but I can rarely make them agree with each other, or even the hand calculations. To the point: I wanted...
Hello All,
I have been searching for load ratings for various weld nut sizes. I feel like this information should be out there based on the nut size and the weld size, but I have so far been unsuccessful. If anyone has seen information like this, could you point me in the right direction...
Could an o-ring's seal integrity be compromised if the sealing surface is powder coated? The gland would remain uncoated and machined to the appropriate surface finish, however the plate that bolts down and presses the o-ring into its gland would have a powder coated surface (as opposed to an...
Has anyone used the XLRotor software to design a drive system for a large industrial belt driven fan? I saw the recommendation for the software from the post below:
thread384-103687
In evaluating the software it appears to be very useful, however I haven't seen anywhere in the tutorials or...
Hello,
I have a welded structure that I modeled using surface bodies. All bodies intersect at what would be welded joints and all lines are split to ensure node-to-node bonding. Something I typically see with models like these is that I have relatively high stress right where one of the members...
Hello,
We’re performing pressure testing on an aluminum pressure vessel. What you’ll see in the attached image is that we have four samples that are tested as follows:
1) Burst test – Pressure increased until unit bursts
2) High pressure / low cycle
3) Low pressure / high cycle
4) Lowest...
Hello,
I have been reviewing a belt and pulley assembly to better understand the loads at work. From my understanding, there is a tight side and a slack side created when the pulley drives the belt. This difference in tension creates the effective pull (Pe = T1 - T2). What I don't understand is...
