I've read in multiple locations that line drilling rivets is beneficial, but I've never seen a technical (comprehensive or otherwise) discussion of why. Does anyone have any links to resources that discuss the why behind this suggestion?
BLUF: Is it possible to mimic a solar loading environment solely in a temperature chamber and, if so, how?
We have an 6061 Aluminum box with a known heat load inside. It needs to be subjected to a solar load IAW MIL-STD-810G, Method 505.4, Proc I. Essentially, it is a 24-hour exposure cycle...
Hi all -
Bottom Line Up Front: I want to develop a design and drafting check procedure.
I manage a small engineering team that designs electronic modules for the communication industry. We have been spending a lot of money on ECNs lately. It seems that the root cause is drawing errors. Our...
I've been trying to figure this out for a week or so and haven't come up with a confident answer, despite my research.
We're trying to come up with the proper profile for our vibration testing and seem to have run into a roadblock.
While I can't be that specific, we need to test 'installed'...
I have the following set-up:
A gear is mounted to a ferrofluidic feedthrough (vacuum to atmosphere seal that allows rotational motion to be transmitted via a ferrofluidic vacuum seal). A shaft (1.5"-2.0" diameter) travels through the axis of the gear and also moves 0.875" up and down.
I...
I have the following set-up:
A brushless motor (w/gearhead) is attached to a pinion. The pinon is mated with a gear (they are normal spur gears). The gear is attached to a shaft with a 20-lb disk (pallet) on top of it that spins at a constant velocity.
The pallet goes through the following...
sahinoz' New to Plastic/Sheet Metal Design post (http://www.eng-tips.com/viewthread.cfm?qid=145113&page=1) got me thinking.
I'm about 4 years out of school and have been at my most recent job for 2 years now. Anyways, I'm working for a process equipment design company. We do mostly small lot...
I've never really dealt with this before and want to make sure my thought process on this.
Setup
A shaft (Di) feeds into a receiving hub (Do). A shear pin of diameter, d, will go through a radial hole that is drilled through both the shaft and the receiving hub. The length of the shear pin...
