Abstract:
This paper presents a new class of flexure hinges, namely, conic-V-shaped flexure hinges (CFHs), which can be used as a generalized model for flexure hinges with profiles such as parabolic-V-shape, elliptical-V-shape, and hyperbolic-V-shape. Compliance and precision equations for the CFHs were derived as a set of nonlinear equations using Castigliano’s second theorem. The parameters of the nonlinear equations inputted to the compliance and precision matrices were based on the generalized equations used for conic curves in polar coordinates. Furthermore, the compliance equations were verified b

AbstractAiming to investigate the drag reduction performance of an antifouling shell rough surface, six different geometries of shell surface texture are simplified as V-shaped riblet, U-shaped riblet, space-V-shaped riblet, blunt-V-shaped riblet, L-shaped riblet, and ∩-shaped riblet. Five kinds of riblets have the same geometric features: groove height and grooved spacing. SST-k-ω model is adopted for the turbulence model. The flow field structure above the different shaped riblet surfaces as well as shear stress and turbulent kinetic energy are analyzed. Moreover, how the flow is influenced

Comprehensive analysis on the modal characteristics of V-shaped electrothermal microactuators is presented in this paper for the first time. Considering the unique geometric characteristics of the V-shaped beam, that is, two inclined beams supporting a movable shuttle, both the lateral and longitudinal deflections are taken into account in the modal analysis. Boundary and continuity conditions are employed to obtain the frequency equation. Natural frequencies are then obtained by solving the frequency equation. Mode shapes corresponding to their natural frequencies are also calculated analytic

This work presents an analytical model to determine nonlinear displacements of electrothermal V-shaped actuators. The nonlinear displacement model of V-shaped beams fixed at both ends is established based on considering the axial deformation of the beam. The 3D model of the V-shaped microactuator was established to verify the theoretical nonlinear model. The evaluation shows that the displacement deviation between the analytical nonlinear model and simulation is approximately 7.7% at the driving voltage of 16 V. This confirms the advantages of the proposed model to predict more precisely the d
