Brian, that is pretty much what I am hoping to do. I just haven't been able to find a sufficient equation that can relate shear strain to torque in a rotating disk with a hole in the center.
Marks' Standard Handbook for Mechanical Engineers comes close, and Shigley's book throws in a couple...
drawoh: The only way to disconnect the generator is to move the engine forward 6-12 inches. If that has to be done it will make it less cost effective than our current method.
Bribyk: The problem with the load cells is two fold. First, it won't account for other accessories and since the...
Bobber, that is an interesting concept and seems like it would work well on small engines. The issue here is the engines I am working on weigh around 40,000 lbs and are enclosed, making any movement incredibly time consuming. The goal is to cut cost while achieving accurate results.
This is...
Well what I am hoping to do is to be able to calculate generator efficiency. I need to know the exact power coming from an engine to the generator. The issue is size, space, and repeatability.
The only instrumentation option is the flex plate, or rotating disk. Any other location is either...
Uh, yeah. So I understand how to calculate torque. My question was how to measure it, and how to turn those measurements into a torque value.
Maybe I should word it like this. I have axial and radial strain at some point on the face of a rotating disk. How do I go from the strain to the...
I need to find a way to measure torque on a rotating disk.
The input force is applied on the outer radius (R) of the disk. The disk then outputs a force to a shaft on the inner radius (r).
I cannot instrument the shaft because space is very limited and a dyno can in no way be used for...
