Abstract
A magnetic suspension type sensing system for space full-degree-of-freedom absolute poses is provided. The system includes a reference platform, multiple quasi-zero stiffness supporting legs and a platform to be tested. The reference platform and the platform to be tested are connected in a spherical hinge mode through the multiple quasi-zero stiffness supporting legs. Each of the multiple quasi-zero stiffness supporting legs includes a lower end spherical hinge, a lower end cover, a positive stiffness unit, a negative stiffness unit, a shaft, a lower end shell, an upper end shell and an upper end spherical hinge.
