Is it possible to simulate inertial load using brake?

Suppose to have an engine attached to a flywheel, I add power, the flywheel start to rotate and oppose a resistance to motion. More power, more resistance. I'm wondering if I can simulate this ...

How much torque does an engine produce when slowing down with no throttle?

If I rev (for example) a small 1.5L 4 cylinder engine up to 4000 rpm in neutral then let off the accelerator (gas) pedal completely, how much torque will the engine produce as it slows down? How long ...

Fly wheel design in MSC ADAMS

I am trying to model a crank rocker mechanism with flywheel. The flywheel is attached on the crank arm join so the crank and flywheel will be rotating with same speed. My aim is to reduce the the ...

Role of the fly-wheel in a fatigue test of a damper

I would like to build a system to carry out a fatigue test of a damper. I am not able to understand the role of the fly-wheel in such a system. The base idea is a crank-shaft mechanism which has a ...

Could this flywheel assembly have been safely built in 1960-62?

Reference: This question from Worldbuilding. I'm writing a time travel story set in 1962 and I'm in need of an analogue to Doc Brown's plutonium (or bolt of lightning!). What I settled on for my ...

Flywheel design equation (angular speed)

What value of average angular speed (ω avg) should we take while designing the flywheel out of the varying speeds of engine depending on its acceleration. And should we just assume Cf(co-eff. of speed ...

Why no big and slow flywheels for utility-scale energy storage?

The flywheel research I see usually focuses on small, high-speed (thousands of RPM) flywheels, often with an emphasis on transportation-related applications. The largest rotating building in the world ...

MSC Adams: “angular kinetic energy” vs “angular momentum about a center of mass”: which is the most relevant measure of the flywheel's storage?

MSC Adams produces several different measures of a rotating body. In a flywheel, what is the difference between 'angular kinetic energy' (in newton-mm) vs 'angular momentum about the center of mass' (...

Optimum spoke shape for wheels made of solid material

Currently I am designing a bicycle sprocket to be laser-cut out of 3mm steel. Steel is heavy, so I want to make some lightening cut-outs, and I want to optimize the shape of the cutouts. I will ...

What do you call a mechanism where rotation is transfered in one direction only?

I have the following to wheels that rotate on the same axis: Assuming that they are stuck together, if I rotate the green one the red one rotates at the same speed and when I stop the green one the ...

Calculate Forces on a Flywheel

I am working on a flywheel currently, and I was wondering what is the force needed to recenter the flywheel when it is spinning and it is nudged slightly off axis? Is it related to gyroscopic ...

What are the technical obstacles for using flywheel-based regenerative braking on bicycles?

Is it possible to convert the energy you would normally lose when braking your bicycle to rotational energy by attaching an extra wheel which would start to rotate once you use your brakes? E.g., when ...
