The Multibody System Dynamics Outstanding PhD Thesis Prize, also denominated Lagrange Award to the best PhD research on Multibody Dynamics, was established in 2017 by the IFToMM Technical Committee for Multibody Dynamics with the aim of recognizing the outstanding achievements of a young researcher (under 35 years old) at the early stage of their scientific career.
       Under the guidance of Professor Yan Chen from Tianjin University and Professor Guowu Wei from Salford University, UK, Dr. Yuanqing Gu was awarded the 2023 Lagrange Award for the PhD thesis entitled ’Design of Deployable Polyhedral Mechanisms and Analysis of Constraint Reduction’. The Lagrange Award is presented annually to recognize the most successful PhD thesis on Multibody Dynamics over the prior year as judged by the evaluation committee. Since its establishment in 2017, a total of nine people worldwide won the Lagrange Prize.
