Do you really want to learn something about "What is 'absorption dynamometer'"? Yes? Let's just get this party started!
Did you know the short answer is…
A device for measuring mechanical forces or power in which the mechanical energy input is absorbed by friction or electrical resistance.
These dynamometers measure and absorb the power output of the engine to which they are coupled.
The power absorbed is usually dissipated as heat by some means.
Example of such dynamometers is prony brake, rope brake, hydraulic dynamometer, etc.
I have selected a few questions and answers to help you understand it:
'absorption dynamometer'
What is power absorption dynamometer...
Power Absorption dynamometers measure and absorb the power output of the engine to which they are coupled. The power absorbed is usually dissipated as heat by some means. Examples of power absorption dynamometer are Prony brake dynamometer, Rope brake dynamometer, Eddy current dynamometer, Hydraulic dynamometer, etc.How is torque measured in an absorption dynamometer...
The torque is measured exactly as in other types of absorption dynamometer, i.e. with the help of a moment arm. The load is controlled by regulating the current in the electromagnets. (a) High brake power per unit weight of dynamometer. (b) They offer the highest ratio of constant power speed range (up to 5 : 1).Thanks for reading up to this point and I hope you have great day.
