New or existing hydraulic system designs are optimized to:

• Meet performance requirements

• Minimize wear

• Increase service life

Criteria to Consider During Optimization

To improve a hydraulic system, Southwest Research Institute (SwRI) engineers consider numerous criteria, including:

• Production cost

• Noise

• Weight

• Size

• Flow capacity

• Efficiency

• Torque and pressure “ripple”

• Durability

• Safety

Factors that Impact System Performance

Engineers evaluate a number of factors to determine their impact on system performance. These factors include:

• Cavitation

• Stability

• Fluid compressibility

• Heat generation

• Leakage

• Stiction

• Aeration

• Windage

• Permeation

• Noise, vibration, and harshness (NVH)
