A multi-disciplinary mechanical element simulator that precisely analyzes the power transmission of single-plate clutches (Uniform Wear/Pressure) and the braking torque and tension ratio (Euler-Eytelwein) of band brakes based on friction coefficient, applied load, contact radius, and wrap angle, verifying friction engagement and braking behavior with 2D graphics.

A premium mechanical element simulator that visualizes the real-time displacement, velocity, and acceleration of a follower using a 2D physics engine, based on parameters such as base circle radius, lift stroke, rotational speed, and cam profile (eccentric, heart-shaped, and constant velocity).

A high-precision 2D simulator that performs real-time calculations of the mass moment of inertia (I), kinetic energy storage, and coefficient of speed fluctuation (Cf) based on the flywheel’s mass, radial dimensions, average rotational speed, and engine pulsation energy, while graphically visualizing rotational velocity pulsations.

Visualizes the spindle speed (RPM), linear feed rate (mm/min), and machining time based on drill diameter and recommended cutting speed for different workpiece materials through a real-time 2D drill physics simulation.

Based on the workpiece diameter and spindle speed (RPM), this tool analyzes the peripheral cutting speed (m/min) of lathe machining, along with the theoretical surface roughness (Ra, Ry) and material removal rate (MRR) based on the feed rate, using a real-time 2D cutting chip simulation.

A simulator that calculates the synchronous speed, actual rotor speed, and slip of an induction motor by controlling the frequency and number of motor poles, while visualizing the V/F pattern curve and the speed deviation of the stator rotating magnetic field in real time.

A simulator that calculates and visualizes in real-time the optimal motor specifications (kW) considering required torque, moment of inertia, acceleration power, and efficiency by setting the load mass, diameter, acceleration time, and target RPM.

This simulator designs the appropriate cable cross-sectional area (mm²) based on load current, transmission distance, allowable voltage drop, and installation environment, while providing a 2D visualization of charge density and cable thermal conditions.

This simulator precisely analyzes the required capacitor bank capacity (kVAR) for power factor correction and electrical energy savings by inputting the active power of the load, the existing power factor, and the target power factor, visualized through a 2D vector phase simulation.
