Powertrain test bed

[Petan123]

Hello,
Please excuse my bad English, I'm from Slovakia
I would like to ask how to measure the efficiency of the powertrain under dynamic loads.
Can you please recommend some literature about measuring the efficiency of the powertrain test bed.

Thank you

Obviously you need to know energy in vs. energy out, but I suspect you already know that.

Are you wanting to know something more specific like how rapidly to apply the load, or if there is an industry standard, etc.?

While I appreciate the language problem, in order to provide an answer to your question you need to be more specific. Exactly what is the configuration of the drivetrain test article? Do you simply wish to know the input-to-output efficiency of the drivetrain at various speed/load conditions? Or do you also wish to determine where the efficiency losses occur within the drivetrain system being tested?
