Manufacturing and characterization of compliant Cardan joints obtained by a new combined fabrication process
The Cardan joint is a key component in many applications. It comprises a number of mechanical elements properly assembled. Building Cardan joints in a single monolithic element using 3D-printing and compliant hinges (CHs), could be economically advantageous. Some applications, especially related to small devices, required small sized Cardan joints. However, the construction of CHs becomes inefficient when their CH size is comparable with that of the extruded filament of the 3D printer. Based on a recent manufacturing process called 3D-PLAST, this drawback can be overcome and CHs of small dimensions can be obtained. Compliant Cardan joints with small dimensions (with external diameters of 4 and 6 mm) have been manufactured by this recent process. This paper presents the kinematic and stiffness performances of these joints to highlight their feasibility and efficiency for small-size system applications.
期刊介绍：
Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics.
Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences.
Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
