✦ Synopsis

A continuum-based con®guration design sensitivity analysis method is developed for dynamics of multibody systems. The con-®guration design variables of multibody systems de®ne the shape and orientation changes. The equations of motion are directly dierentiated to obtain the governing equations for the design sensitivity. The governing equation of the design sensitivity is formulated as an overdetermined dierential algebraic equation and treated as ordinary dierential equations on manifolds. The material derivative of a domain functional is performed to obtain the sensitivity due to shape and orientation changes. The con®guration design sensitivities of a ¯y-ball governor system and a spatial four bar mechanism are obtained using the proposed method and are validated against these obtained from the ®nite dierence method.
