Many engineering systems are ill-defined and imprecisely known, due to fuzziness, especially in the conceptual/preliminary design phase. In this work, a fuzzy kinetostatic methodology is proposed for the dynamic analysis of mechanisms involving imprecision. The fuzzy dynamic bearing reactions as well as driving torque are computed using the proposed method. The analysis of a high-speed planar mechanism for path generation is considered to illustrate the computational aspects of the approach. The fuzzy analysis provides the variation of system performance over the entire range of design parameter space compared to the traditional sensitivity analysis approaches which give variations in system performance only at one design point.
