Abstract: Mobility is a basic property of a mechanism. The aim of mobility analysis is to determine the number of degreesoffreedom (DOF) and the motion pattern of a mechanism. The existing methods for mobility analysis have some ...

Abstract: Multi-loop coupling mechanisms (MCMs) have been widely used in aerospace engineering, architectural design, and outdoor activities. This paper proposes a general method for analyzing the singularities of MCMs using geometric ...

Abstract: Two rotations and one translation (2R1T) parallel kinematic machines (PKMs) are suitable for the machining of complex curved surfaces, which requires high speed and precision. To further improve rigidity, precision, and ...

Abstract: A general method for the analytical elastostatic stiffness modeling of overconstrained parallel manipulators (PMs) using geometric algebra and strain energy is proposed. First, an analytical solution of the constraint and ...
