- Elastomer Bumpers vs. Air Cushions: A Frequency Response AnalysisCompare elastomer bumpers and air cushions using 5 measured response signals: impact energy, peak force, rebound, settling time, and temperature in service.
Designing Deceleration Profiles to Minimize Cycle TimeDesign pneumatic deceleration profiles using Parker's 50% cushion-entry speed warning, stopping-distance math, energy limits, traces, and acceptance tests.
Repeatability vs. Accuracy: Defining Pneumatic Cylinder Positioning CapabilitiesLearn how to separate repeatability, position error, resolution, linearity, and running accuracy, then build a defensible pneumatic cylinder acceptance test.
Load Mass vs. Velocity: Plotting the Cushioning Capacity ChartPlot a cushioning capacity chart correctly using total moving mass and speed at cushion entry, then screen the exact cylinder model and operating case.
Cavitation Risks in Hydraulic Shock Absorbers Used with PneumaticsDiagnose suspected cavitation in hydraulic shock absorbers, separate it from aeration, and verify 8 model-specific limits before safely replacing the unit.
Servo-Pneumatics: Modeling the Compressibility Factor in Control LoopsModel a servo-pneumatic axis with four core states, ISO 6358 valve data, absolute chamber pressure, local linearization, identification, and validation.
Hysteresis Loops in Proportional Pressure Control of CylindersMeasure cylinder pressure-control hysteresis with matched rising and falling steps, a full-scale formula, synchronized traces, and model-specific limits.
Deadband Analysis in Pneumatic Cylinder Friction CompensationUse 2 chamber-pressure traces and position data to separate cylinder friction deadband from valve dead zone, then validate compensation without hunting.
The Effect of Tubing Compliance on Cylinder Positioning StiffnessCalculate how 10 m of 8 mm OD, 5 mm ID tubing adds 196 cm³ to a pneumatic cylinder circuit, then improve positioning stiffness without restricting airflow.
