Animations of linkage movement.

5SS Spatial Steering Linkage

Mark Plecnik designed this spatial 5SS steering linkage to increase the track and increase the camber as the vehicle turns.

MechGen 2

Mechanism Generator 2.0 (MechGen 2)

We have a trial version of our Mechanism Generator 2.0 software available. MechGen 2 reads five task positions of a moving part in SolidWorks and generates a set of linkages that approximate the positions within specified tolerances. An animation previewer shows how each linkage moves. Select one and MechGen 2 generates the solid model of the linkage.  

This is the result of excellent work by Alex Arredondo and Kaustubh Sonawale.

This video demonstrates the operation of MechGen 2:

Folding movement for wings for the Icon A5

This spherical four-bar linkage concept by Kaustubh Sonawale guides the wings of the Icon A5 in the movement shown in the animation.

Spherical linkage concept to fold a wing

This is a spherical four-bar linkage concept by Kaustubh Sonawale designed to fold the wings of an Icon A5 small aircraft.

Spare tire deployment linkage

Kaustubh Sonawale designed this four-bar linkage to move a truck spare tire from a stowed position to the deployed position.

Hardtop Convertible New

Revised Three-panel Hardtop Convertible Linkage

Oscar Alonso replaced the parallelogram drive linkages of the three-panel Volve C70 hardtop convertible with quadrilateral linkages, so it deploys farther and stows more compactly. The wheelbase of this vehicle approaches that of the Mercedes CL500. He used our Mathematica linkage synthesis notebook and our Mechanism Generator add-in for SolidWorks.

Spherical Fourbar

Spherical Four-Bar Linkages

Here is something new. Our Mathematica notebook can find defect-free spherical four-bar linkages that guide a body through five orientations in a tolerance zone near a specified set of task orientations.

Four-bar Synthesis

Linkage Synthesis Demonstration

This shows the operation of our Mathematica notebook for five-position synthesis of a four-bar linkage.   The link to download and try this notebook is on our Linkage Synthesis page.

Convertible Hardtop

Hardtop Convertible Linkage

This SolidWorks animation of the drive linkage for a hardtop convertible was prepared by Oscar Alonso from U.S. Patent No. 7014247 (Dilluvio) and previous references.

Six-bar Retrieval Linkage for an ROV

This six-bar linkage was designed to extend from the body of an underwater ROV to retrieve and stow objects positioned by a robotic arm.
