SimHydraulics 1.6

Modeling Hydraulic Components

SimHydraulics includes spring-loaded and gas-charged accumulator models, as well as two pipeline models:

• The standard pipeline block models pipelines with circular and noncircular cross sections and accounts for frictional pressure loss and fluid compressibility.
• The segmented pipeline block accounts for frictional pressure loss, fluid compressibility, and fluid inertia and enables you to model phenomena, such as water hammer.

A library of local resistance blocks lets you include pressure loss associated with elbows, bends, and cross-sectional flow area changes.

SimHydraulics provides actuators and pumps that let you:

• Model hydraulic cylinders and rotary actuators, including effects such as cylinder friction
• Model hydraulic motors, fixed-displacement pumps, and variable-displacement, pressure-compensated pumps for power exchange with rotational mechanical components

The valves library lets you model:

• Directional valves, including 2-way, 3-way, 4-way, shuttle, check, and pilot-operated check valves
• Flow control valves, including ball, needle, poppet, and pressure-compensated flow control valves
• Pressure control valves, including pressure-reducing and pressure-relief types

The valves library also includes actuator models to simulate electromagnetic, discrete and proportional actuators, and servo-valves.
