Hydraulic System Designer

Hydraulic System Designer

Design, simulate and validate hydraulic circuits in your browser

Hydraulic System Designer is a free, offline, browser-based tool for building hydraulic schematics and running real-time simulations. Draw pumps, valves, cylinders, motors and sensors on a canvas, then analyze stability, efficiency, thermal behavior, cavitation and water-hammer — no installation and no license required.

Features

• Visual circuit editor

  Drag-and-drop ISO 1219 components, connect oil lines, and catch topology errors before you simulate.

• Real-time simulation

  A semi-implicit solver computes pressures and flows every frame, with fault injection and live oscilloscope charts.

• Stability & frequency analysis

  Bode, Nyquist and root-locus plots reveal gain/phase margins and resonance of your control loops.

• Efficiency & thermal

  Track pump/motor efficiency, heat generation and oil temperature to size coolers and cut energy cost.

• Cavitation & water-hammer

  Quantitative cavitation/aeration modeling plus water-hammer severity grading protect your components.

• Reports, BOM & export

  Generate sign-off reports, bill-of-materials with cost, and export SVG, DXF, PDF and FMU.

How it works

1. 1

   Build

   Place components from the palette and wire them into a circuit.

2. 2

   Simulate

   Press Run to watch pressures, flows and temperatures evolve live.

3. 3

   Validate

   Open the report to check stability, efficiency and cavitation, then export deliverables.
