A dynamically isotropic mechanism is useful for vibration isolation since such a mechanism can be used to attenuate the first six modes of vibration effectively and equally from a sensitive payload. A Gough-Stewart Platform (GSP) has been proposed, in literature, for six component vibration isolation. The conventional GSP, however, fails to give a dynamic isotropy; hence a Modified Gough-Stewart Platform (MGSP) is considered in this work. The force transformation matrix, together with a geometry-based approach, is used to obtain closed-form analytical solutions for dynamic isotropy in an MGSP at its neutral position. The more general case of variation of the centre of mass of the payload from the top platform is considered. The geometric approach presented in this work is simpler, faster, and more systematic than the previously existing methods. The configurations obtained with the above approach were successfully validated with the simulation results obtained using ANSYS®. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
