FP 4701 - Advanced Fluid Power

3 lecture hours 2 lab hours 4 credits
Course Description
Advanced concepts in fluid properties, linearized models for valve, pump, and motors are applied to the steady state modeling of fluid power systems and components. Pump control strategies (pressure compensation, load sensing, torque limiting, power limiting, etc.) are discussed relative to system performance goals. Dynamic analysis of hydraulic components and systems is accomplished using computer based methods (e.g., Matlab/Simulink). Laboratory work support lecture material. (prereq: FP 2701 )
