Six-bar Linkage Design for Mechanical Computation

Six-bar linkages

Our paper Numerical Synthesis of Six-bar Linkages for Mechanical Computation provides the mathematical theory that underlies the synthesis of a six-bar linkage with an input-output relationship that approximates a specified function. This describes how the Stephenson III six-bar linkage that sets the elevation for a ballistic trajectory was designed.

2013 Energy Invitational: Video

Race teams from 20 high schools and colleges competed in energy time trials at Adams Motorsports Park on May 11, 2013 at the fourth UCI Energy Invitational. This video captures the spirit of the event.

Ballistic Function

Mechanization of the ballistic function

This Stephenson III six-bar linkage sets the elevation of a ballistic trajectory to reach a specified distance downrange given an initial velocity of 500 m/s. This function is described in Computing Linkages by A. Svoboda (pg 285). Mark Plecnik obtained this linkage after evaluating almost 100,000 different designs.

This poster was prepared as a gift to Ken Waldron on his 70th birthday and given to him at a conference organized in his honor. Anuj Taneja generated the SolidWorks model in 2006 from the original drawings of the Adaptive Suspension Vehicle. I recently found the electronic files and Kaustubh Sonawale generated the four-view drawing. The ASV is an important feat of engineering and the stories shared by those who worked on it were wonderful.
