Vane Pump-life Calculation

Vane Pump-life Calculation

Vane Pump-life Calculation

(OP)
How do you calculate cummulative damage on a pump?  It is fairly straight-forward with structural components through the use of Rainflow analysis, level-crossings, etc..  However with pumps, if you have real-time pressure, flow and temperature measurements, how do you combine them into a damage assessment?  Thanks in advance!
