Kinematic Simulator

Kinematic Simulator is an engineering tool for constructing and analyzing two-dimensional mechanical systems. Users create mechanisms from rigid links, fixed points, rotating joints, and sliding joints, then apply motion to one component and observe how the complete assembly responds. There is no storyline, playable character, or campaign. The objective is to test whether a mechanism can move correctly and study its position, velocity, acceleration, and generated path before producing a physical model.

Constructing a Planar Mechanism

A design begins by placing joints on the workspace and connecting them with links. Revolute joints allow components to rotate around a pin, while prismatic joints restrict movement to a straight path. Selected joints can be fixed to the ground, and one link is assigned as the input crank or motor. The simulator can represent four-bar linkages, slider-crank systems, multi-link chains, and mechanisms containing several sliders.

Watching Motion and Recording Results

After the mechanism is assembled, the user starts the simulation and changes the speed or direction of the driving link. The program calculates the position of connected bodies while the model moves. Trace points can be attached to selected links to display their trajectories. Some simulators also generate graphs or exported data for displacement, angular position, velocity, and acceleration throughout a complete cycle.

The usual workflow includes:

·         placing fixed, rotating, and sliding joints;

·         connecting joints with rigid links;

·         grounding the stationary parts of the assembly;

·         selecting an input link and setting its rotational speed;

·         running, pausing, or advancing the simulation manually;

·         tracing the path of a chosen point;

·         reviewing position, velocity, and acceleration results.

Experiments Instead of Traditional Levels

Kinematic Simulator does not contain numbered levels, enemies, scores, or unlockable abilities. Preset mechanisms and tutorial exercises serve as examples that can be studied in any order. Progress comes from building more complex systems and correcting designs that contain too many degrees of freedom, incompatible joint positions, or links that cannot complete their intended motion. A valid one-degree-of-freedom mechanism can usually begin moving automatically after its constraints are defined correctly.

To use the simulator effectively, start with a basic four-bar or slider-crank model and confirm that every required joint is connected. Ground the frame, assign one input, and move it slowly through the full range before increasing speed. If the assembly locks, inspect the link lengths, joint locations, and slider directions. Trace points can then be used to compare the actual motion with the required output path. Completed mechanisms may be saved, exported, or compared before the design is transferred to CAD or manufacturing.
