Abstract

A device and a method for measuring a rotation angle of a spherical hinge joint with a football-shaped structure are provided. The measuring device includes a driving electrode, and an induction electrode system. During measurement, the driving electrode and induction electrode system are both installed in a measured spherical hinge joint. The spherical hinge joint includes a ball socket base, and a ball head installed in the ball socket base. The driving electrode is fixed to the ball head. The induction electrode system includes multiple regular hexagonal spherical electrode plates, and one or more regular pentagonal spherical electrode plates. Five regular hexagonal spherical electrode plates are all arranged around any one regular pentagonal spherical electrode plate, respective regular hexagonal spherical electrode plates and respective regular pentagonal spherical electrode plate are assembled to form a spherical shell structure.
