Design, simulate and analyze planar mechanisms

DXNest Motion is browser-based kinematics software for constructing, simulating and analyzing planar mechanisms, including linkages, sliders, gears, racks, eccentric drives, rollers and rolling segments.

Build the mechanism on an engineering canvas, solve its full cycle, inspect trajectories and motion parameters, compare graphs, and export the results without installing desktop software.

  1. 1

    Construct

    Create links, kinematic pairs, sliders, gear and rack transmissions, eccentric drives, roller contacts and rolling segments directly on the canvas.

  2. 2

    Simulate

    Run a complete input cycle with a constraint solver and animate the resulting motion, trajectories, velocity vectors and acceleration vectors.

  3. 3

    Analyze and export

    Review calculated point and link series, overlay graphs from different mechanisms, and export drawings, data tables and charts.

Capabilities

One workspace from mechanism layout to motion data

DXNest Motion keeps construction, calculation, visualization and export connected to the same mechanism model.

Kinematic analysis

See what every point and link does through the cycle

The calculation engine produces synchronized series for the complete mechanism, ready to inspect as values, vectors, trajectories and graphs.

Points

X and Y position, velocity and acceleration over the full input cycle.

Links and segments

Angle, angular velocity and angular acceleration for moving members.

Roller contacts

Clearance and centre distance through the cycle, including rigid-contact configurations.

Graphs and comparison

Plot calculated parameters and overlay curves from mechanisms open in different tabs.

Workflow

From a mechanism concept to reusable results

  1. 01

    Build the geometry

    Place supports, links, sliders, gears and specialized contacts on the engineering canvas.

  2. 02

    Set dimensions

    Enter lengths, coordinates, angles, radii and formulas, then choose which parameters stay fixed.

  3. 03

    Solve and inspect

    Analyze the input cycle and review animation, trajectories, vectors, calculated series and graphs.

  4. 04

    Save and export

    Keep the project in your account and export drawings or calculation data for further engineering work.
