Kinematic Analysis of a 3-PSP Spatial Motion Platform

This paper presents the kinematic analysis of a 3-PSP motion seat to be used as a flight simulator. To ensure the pilot’s security, all passive joints are kept on the base plate rather than under the moving platform, and thus, use an upside-down configuration relative to previously published results in the literature. Although the resulting kinematic is more complex, it can still be solved in an analytical form, even when a non-symmetric base and moving platforms are used.
