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.
Kinetic Sculpture: Bucephale
This video shows a kinetic sculpture of a horse by the artist Francois Hameury. His website is http://hameury.sculptures.pagesperso-orange.fr/index.htm
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.
Geometric Design of Linkages, second edition
I am pleased to say that the second edition of my book, Geometric Design of Linkages, is now available, and I have to express my sincere gratitude to my co-author GimSong Soh, who helped make it happen. You can find more information at the Springer Verlag web-page, GDL on Springer.com. It is also already on […]
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.
21st Century Kinematics
This is a draft of my editorial on 21st Century Kinematics for the Journal of Mechanisms and Robotics. It is a follow-up to my previous editorial on Kinematics, Polynomials and Computers. I would welcome your feedback.
2011 UCI Energy Invitational
The 2011 UCI Energy Invitational will be at Willow Springs International Motorsports Park on March 22-23, 2011. The Streets of Willow Springs will be set up with a highway, autocross and staged idle sections to challenge the energy usage of all types of vehicles. How far can your vehicle travel in an hour on this […]
Kinematics, Polynomials and Computers–A Brief History
Select this link to the .pdf of Kinematics, Polynomials, and Computers–A Brief History, which is a summary of the history of the kinematics of mechanisms and robotics with a focus on the challenge of solving the polynomial equations that arise in their study. It is a draft of my February 2011 editorial for the ASME Journal of […]
Peugeot 407 Convertible Hard Top
This is a video on Yahoo! that shows the movement of the Convertible Hard Top of the Peugeot 407. The two side rails fold out from the back, and provide guides for the glass panels that move out to become the top.
