Real-Time Animation
Watch mechanisms move at the speed you set. Pause at any position to inspect geometry. Show or hide reference markers and dimensional labels.
2D Mechanisms Analyzer
Modified:
Published:
Mechanism analysis in a textbook gives you one answer for one configuration. Change any parameter, and you start the calculation over. The 2D Mechanisms Analyzer is a suite of interactive browser-based simulators that gives you the full picture: adjust geometry in real time, see kinematic and force analysis curves update instantly, compare configurations side by side, and export professional-grade data for further analysis. No installation required. #MechanismDesign #EngineeringSimulation #PlanarMechanisms
What Every Simulator Provides
Kinematic and Force Analysis
Full displacement, velocity, acceleration, and force profiles computed analytically (not approximations). Interactive charts with hover data readout.
A/B Configuration Comparison
Save one configuration, change parameters, and overlay both datasets on every chart. See exactly how each parameter affects every output.
Professional Downloads
Export CSV data, PNG charts, design specifications with manufacturing tolerances, lab report templates, and parametric CAD scripts.
Available Simulators
Crank-Slider Mechanism
The most widely used mechanism in engineering: IC engines, compressors, presses, and packaging machines. Seven analysis plots, three engineering presets, offset support for quick-return analysis, and crank torque computation.
Four-Bar Linkage
The foundation of mechanism design: Grashof condition analysis, coupler curve tracing, angular position and velocity profiles, transmission angle monitoring, and four engineering presets (crank-rocker, double-crank, double-rocker, parallelogram).
Who Is This For?
- Mechanical engineering students: Develop intuition for how parameters affect kinematic behavior. Run structured experiments in our Mechanism Design and Simulation course.
- Practicing engineers: Quick parametric studies before committing to CAD. Export data directly into your analysis workflow.
- Educators: Ready-made demonstrations for lectures. The A/B comparison feature is built for classroom “what-if” moments.
- Competitive exam candidates: Verify textbook problems and build confidence in the formulas for PE, GATE, and FE exams.
Coming Soon
Future simulators planned for this suite:
Four-Bar Linkage
Grashof condition checking, coupler curve tracing, transmission angle analysis, and motion classification.
Geneva Mechanism
Indexing motion profiles, dwell periods, pin engagement angles, and angular velocity of the driven wheel.
Cam-Follower
Rise/dwell/return profile design, pressure angle analysis, jerk profiles, and follower displacement curves.
Scotch Yoke
Pure sinusoidal motion generation, comparison with crank-slider, and harmonic analysis.
