Free Vibration of Mistuned Aircraft Engine Bladed Discs,e entire shaft with discs were carefully examined and compared with a tuned system to discover resonance conditions and coupling effects. Mistuning caused considerably more intensive multistage coupling than the tuned system and distorted the mode shape nodal diameters.

Operation Modes in Lower-Mobility Parallel Manipulators,apers but the physical meaning of an operation mode is not always clear. Indeed, even if in some cases an operation mode can be associated with an understandable motion type e.g., three pure translations or a spherical motion, in some other cases, such an association is not straightforward. Therefor

Design of Cable-Driven Parallel Robots with Multiple Platforms and Endless Rotating Axes,perations it is desirable to have an additional actuated serial kinematics on the platform. This usually comes along with the problem of extra weight and energy supply for the motors on the platform. In this paper we present a new approach to the problem by introducing a hybrid design with coupled p

The corresponding matrix representation of a chain’s kinematics is a product of two exponentials in the homogeneous representation of the Euclidean group. While the DH notation is based on sound kinematic intuition, it is not obviously natural in mathematical terms. In this paper, we us

Free Vibration of Mistuned Aircraft Engine Bladed Discs,. Each bladed disc had a different number of rotor blades. Free vibrations were examined using finite element models of single rotating blades, bladed discs, and an entire rotor. In this study, the global rotating mode shapes of flexible mistuned bladed discs-shaft assemblies were calculated, taking
