What You Can Adjust and Explore
This free, browser-based crank-slider (slider-crank) mechanism simulator lets you change every parameter below and watch the animation and the displacement, velocity, and acceleration charts update in real time.
Adjustable parameters
- Crank length r: 20 to 100 mm
- Connecting rod length l: 80 to 200 mm
- Slider offset e: -50 to 50 mm (creates quick-return asymmetry)
- Slider load force: 0 to 1000 N
- Crank speed: 10 to 120 RPM
- Manual crank angle: 0 to 360 degrees, with a selectable step angle
One-click presets
IC Engine, Air Compressor, Hydraulic Press, and Quick-Return (offset) load realistic parameter sets for real machines.
What it computes
Slider stroke, peak and RMS velocity, peak acceleration, connecting-rod angle, transmission angle, mechanical advantage, and crank torque, plotted against crank angle or time, with two-configuration A/B comparison and downloadable CSV data.
Frequently asked questions
What can I adjust in this crank-slider simulator?
Crank length (20 to 100 mm), connecting rod length (80 to 200 mm), slider offset (-50 to 50 mm), slider load force (0 to 1000 N), and crank speed (10 to 120 RPM), plus manual crank-angle control and one-click presets for an IC engine, air compressor, hydraulic press, and an offset quick-return.
What does the simulator calculate?
It plots slider displacement, velocity, and acceleration over a full crank rotation and reports the stroke, peak and RMS velocity, peak acceleration, connecting-rod angle, transmission angle, mechanical advantage, and crank torque.
Can it model a quick-return mechanism?
Yes. Increase the slider offset or choose the Quick-Return preset, and the forward and return strokes take unequal times, giving the asymmetric quick-return velocity profile used in machine tools.
Is it free, and does it work on mobile?
It is completely free and runs in any modern web browser on desktop, tablet, or phone with no installation. You can also download CSV data and engineering resources.
