Publication number: 20220003532Abstract: The present invention discloses a quasi-zero-stiffness (QZS) based six-degree-of-freedom (6-DOF) absolute displacement and attitude measurement device. A lower end coil and an upper end coil are respectively charged with currents in the opposite directions; The electromagnetic field and the magnetic fields of an upper magnet and a lower magnet per se are mutually acted to produce an electromagnetic stiffness opposite to the stiffness of a spring. The stiffness of the whole leg is close to zero stiffness. When the to-be-measured platform generates space motion, the reference platform is in the stationary state. At this point, the deformation amounts of the six legs can be measured by laser displacement sensors. The six deformation amounts are respectively inputted into the displacement and attitude resolver, and by forward kinematic solution of the 6-DOF device, the displacement and the attitude of the to-be-measured platform can be obtained.Type: ApplicationFiled: December 14, 2020Publication date: January 6, 2022Inventors: Huayan Pu, Jinglei Zhao, Jun Luo, Jiyun Zhao, Qinghua Kong, Jiheng Ding, Min Wang, Yi Sun, Zong Li, Long Bai, Yan Peng, Shaorong Xie
