Content
The module covers fundamentals of mobile hydraulic systems as used in off-highway and mobile machinery, with a focus on practical design and analysis. Topics include fluid properties and conditioning (viscosity, contamination, temperature control), pressure/flow relationships, laminar vs turbulent regimes, cavitation avoidance, energy and loss budgeting, and heat rejection. Component-level principles for mobile hydraulic pumps, motors, valves, lines, filters, coolers, and actuators are linked to efficiency, reliability, and mobile control strategies (load-sensing, pressure-compensated metering). Students learn core equations, dimensioning lines and inlets, estimating losses and cooler sizes, and interpreting efficiency and performance maps typical of mobile machinery duty cycles. Safety, diagnostics, and maintenance practices (cleanliness, monitoring, case drain and inlet measurements) are emphasized to connect theory with field reliability in mobile machinery engineering and their work environments.
Prerequisites
- Engineering math and physics (statics/dynamics, basic thermodynamics, fluid properties)
- Basic mechanical engineering foundations (materials, machine elements) and proficiency with unit conversions
Learning Goals
After participating in the module, students are able:
- to explain how fluid properties, flow regime, and circuit architecture influence efficiency, losses, and cavitation risk.
- to explain principles of hydraulic lines, inlets, filters, coolers, pumps, motors, valves, and actuators using the key pressure/flow equations and efficiency definitions.
- to classify and compare mobile system architectures (open circuit, closed circuit, load-sensing, hydrostatic) and identify the components required for each.
- to diagnose hydraulic performance issues from measurements (case drain, inlet pressure, temperature, cleanliness) and propose corrective actions grounded in fundamentals.
