All features included in version 2.0. Educational use recommended for mechanical engineering students and professionals.
Real-time transmission angle calculation displays jam and caution thresholds as you manipulate the crank, providing instant feedback on mechanical advantage throughout the rotation cycle.
Watch the complete path traced by any point on the coupler link. The Atlas mode systematically explores 57 different coupler positions, revealing the dramatic curve variations from identical base linkages.
Automatic identification of linkage type—crank-rocker, drag-link, double rocker, or non-Grashof—updates instantly as you adjust link length sliders, teaching mobility criteria through direct manipulation.
Point your camera at a physical mechanism to trace its geometry, measure link ratios, and analyze its motion characteristics. Bridges the gap between theoretical study and real-world machinery.
Continuous crank rotation lets you observe the full motion cycle hands-free, while transmission angle warnings highlight dead points and regions of poor mechanical efficiency automatically.
Velocity and acceleration graphs show per-radian derivatives, not time-based values. Drag across the plots to scrub through the cycle while the mechanism diagram updates synchronously.
Amuna Beacon delivers tactile understanding of four-bar linkage behavior through direct manipulation. Drag the crank pin and feel the mechanism resist at dead points. Adjust link lengths via sliders and watch the Grashof classification flip from crank-rocker to double rocker instantly. This immediacy transforms abstract kinematic principles into concrete experience.
The synthesis solver reverses traditional design workflows. Instead of choosing link lengths and hoping for desired positions, you place three target poses on the canvas. The app calculates the exact fixed pivot locations required to carry a coupler point through those positions, revealing the geometric relationships behind position-guided design methods taught in advanced mechanism courses.
Motion plots display velocity and acceleration per radian of input rotation, isolating the kinematic geometry from speed variations. This representation matches analytical derivations in textbooks while remaining visually interpretable. Peak values, rocker swing angles, and time ratios appear as live readouts, updating as you modify the mechanism geometry in real time.
Amuna Beacon was built on the principle that mechanism kinematics cannot be learned from static diagrams alone. Textbook illustrations show one frozen configuration, but four-bar linkages are fundamentally dynamic. Understanding requires feeling how the crank resists near toggle positions, watching how coupler curves morph with tiny coupler point shifts, and seeing transmission angles collapse toward dead points. This app transforms those abstract concepts into tangible experiences through touch-responsive simulation refined for educational clarity rather than entertainment.
