RISA New 3D Mechanism for Modeling the Passive Motion of the Tibia–Fibula–Ankle Complex
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A great number of kinematic, kinetostatic, and dynamic models of human diarthrodial joints, such as the hip, the knee, and the ankle, have been presented in the literature. On the contrary, ...
A New Kinematic Model of the Passive Motion of the Knee Inclusive of the Patella
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Knee models that can reproduce the motion of the joint are considerably attractive in many applications like prosthesis and orthosis design, rehabilitation, and setting and design of surgical ...
A New Technique for Clearance Influence Analysis in Spatial Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a technique for assessing the influence that clearance in the kinematic pairs of a mechanism has on accuracy. The technique works for both planar and spatial, open-, and ...
A Family of 3-DOF Translational Parallel Manipulators1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article addresses parallel manipulators with fewer than six degrees of freedom, whose use may prove valuable in those applications in which a higher mobility is uncalled for. In particular, ...
Position Analysis of a New Family of 3-DOF Translational Parallel Manipulators*
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents the position analysis of a new family of 3-limbed 3-dof parallel manipulators, whose output links exhibit a motion of pure translation with respect to the base. Each limb ...
Dynamics of a Class of Parallel Wrists
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a dynamic model of parallel wrists with all links constrained to have a spherical motion with the same center. The model can also be applied to serial wrists. The model, ...
A Spatial Mechanism With Higher Pairs for Modelling the Human Knee Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By generalizing a previous model proposed in the literature, a new spatial kinematic model of the knee joint passive motion is presented. The model is based on an equivalent spatial parallel ...
A New Algorithm Based on Two Extra-Sensors for Real-Time Computation of the Actual Configuration of the Generalized Stewart-Gough Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that the direct position analysis of fully-parallel manipulators provides more than one solution, i.e., more than one configuration of the mechanism is possible for a given ...
Inverse Static Analysis of a Planar System With Flexural Pivots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents the inverse static analysis of a two degrees of freedom planar mechanism with flexural pivots. Such analysis aims to detect the entire set of equilibrium configurations ...
Position Analysis in Analytical Form of the 3-PSP Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the direct and the inverse position analysis of a 3-dof fully-parallel mechanism, known as 3-PSP mechanism, is addressed and solved in analytical form. The 3-PSP mechanism consists ...
