True we didn't work to code, correlation is the main game, although I did used to have to sign an actual official report that said , in essence, vehicle model xyz has been tested in accordance with procedure abc and it passed.

We used to do a regression analysis on each iteration of the app when it was released. This would run through a standard suite of models and we'd then check the results remained the same. Or not. Problem is it's a non production task, so nobody has time to do it, so we just carry on with the old...

As this makes clear, the skid unit (tractor terminolgy) holding the turbine/gearbox/rotor system is the strength member, the cabin is just an alloy tube for holding passengers.

So +2 degrees in 2006 compared with 1986 according to the expert, or +0.25 deg in fact. +3 degrees by 2020, or +0.45 in fact.

You've drawn a bicycle wheel, so the empirical answer is yes.

Better wait 28 years. Or at least 13.

That's why they have a preload in the springs. Adding a check strap to the rear axle will increase the tendency to spin if the inside wheel lifts, as it suddenly overloads the outer wheel which can then break away. So the proper solution is to design a 2 stage coil spring with a soft initial...

How is a year of extreme weather (if that was the case) anything to do with climate? The IPCC defines climate as a statistical description of the average weather over a period of time, typically 30 years. The U.N. Intergovernmental Panel on Climate Change (IPCC) admits having “low confidence”...

MUX is the green block on your diagram. End of conversation.

The signal from the MUX needs to include k1 and k2. Is there not a tutorial on this?

In theory it seems a good idea, sometimes in practice it is the other way round. It can be useful to force a sudden change in weight transfer across the axle in limit handling events.

For advanced woowoo I suggest the FEA forum, the altair ones don't get much traffic.

I have done the non indexed method as an exercise but since all of my data is triggered the index method is more robust and easier.

Any geo engineering project will create winners and losers. An example of this is cloud seeding, which has threatened to start wars in SE Asia, and in Tasmania for example is used to increase rainfall in the catchment for the hydro dams, at the expense of causing reduced rainfall in the...

Professionals design springs for road use such that they have a minimum preload of X with the wheels at full droop, ie on a 2 post hoist. Amateurs don't, they worry about powder coating.

In theory it doesn't matter where the trial weights are located on each plane relative to the other plane, I think. But i haven't done this in a long time(25 years). I'd have thought so long as all measurements and locations were referenced to a single shaft reference marker it would be OK.

It isn't sent to simulink it is a co sim with simulink. Is there not a tutorial on this?

You do the 2 single plane balances by record the vibration or velocity at both planes. Same number of runs just more data. Maths is here https://www.eng-tips.com/threads/diy-crankshaft-balancing-with-an-oscilloscope.511892/#post-8933361

Loosely speaking you need to define the various parameters as design variables in adams, and then pass values to them from your simulink.

2 plane balancing is more complex than 2 1 plane balances, as you need to consider the influence coefficients from plane1 to plane 2 and vice versa.
