Sounds like you need a coauthor, or at least advice from a person who would quality to be a coauthor. I know that, while some of my papers needed the coauthor(s) to be publishable, all of them benefited from advice from qualified people.
Possible coauthors start with the authors of the...
What type of motor are you using to drive the gear? Each of these are controlled differently, and load the gear differently. This would help us to interpret what you were told on Reddit.
1) A small servo typically controlled by an Arduino?
2) An industrial servo motor?
3) An induction...
Your list is of severe overload or poorly designed joint failures. A common real world failure mode is bolt loosening due to intermittent loss of preload caused by impact or vibration. A classic example is the old model Ruger Super Blackhawk 0.44 Magnum revolver. A required accessory was a...
Fentanyl has a lethal dose of about 2 milligrams (0.002 grams), and is currently responsible for about 75,000 accidental deaths per year in the US. One of those deaths was the son of a friend. It qualifies on both the total number of deaths and on the lethal dosage.
Industrial servomotors are available in that size range. One such manufacturer (not the only one) is Allen-Bradley. Check out this link: https://www.rockwellautomation.com/en-us/products/hardware/allen-bradley/motion-control/rotary-servo-motors/mma-series-motors.html. Click into the technical...
Since a circle is a limiting case of an ellipse, just cannonball into the center of a circular pool, and find if the waves come back and fling you up. Or drop something into the center of a round bucket of water.
Your PDF shows what appears to be a centrifugal blower, but does not show what we need to know:
1) A detailed drawing of the portion of the shaft around the seal, the blower housing around the seal, and the seal housing.
2) What are you sealing - is it a liquid or gas? What liquid or gas?
3)...
I once designed a four bar linkage. I first did a literature search looking for an analytical procedure, and found nothing that was of practical use. So that left trial and error, but not random trial and error. It was a series of steps:
1) Define the desired motion with a sketch
2) Write a...
A factor that could account for some of your observations is the relative mass of the ball and the spring. From the SMI Handbook of Spring Design: "These equations assume that the spring is massless and should only be used when the spring mass is less than 1/4 of the mass to be accelerated."...
That's the same that I get assuming 10 meters per minute and a 70 mm diameter conveyor drive roll. The next step is:
Another way to get the drive torque is to place the maximum load on the conveyor, wrap a long string around the drive roll, and pull the string using a spring scale. From the...
This.
This is a machine design problem. Expanding on what @Baluncore said, the general procedure is as follows:
1) Decide what speed the conveyor needs to run -- how fast to move the panels in m/sec.
2) Calculate the RPM of the conveyor input shaft.
3) Figure out the necessary torque of the...
You have a system with resonant frequency of 0.31 Hz that is excited at 0.6 Hz. The response will be small because the magnitude of the response is determined by the mass of the system and the magnitude of the excitation. Then you added a second system with a resonant frequency of 0.6 Hz...
But you can give us more information. If I understand your posts so far, you have an object of approximate dimensions X cm by Y cm by Z cm. That object is heat soaked at 85C for 30 days, then at 500C for 1/2 hour. Components inside the object must be kept below 100C to 110C.
If that...
