In this paper, analysis and design of an underactuated compliant variable stroke mechanism are presented by employing its pseudo-rigid-body model (PRBM). During the design two cases are considered: prescribed output loading and constant input torque. It is shown that this mechanism is suitable where variable stroke is required corresponding to variable output loading. It is also observed that this mechanism is capable of providing nearly constant force over a wide range of input. The analysis and design approaches introduced in this study are also applicable for other similar underactuated compliant mechanisms.

On the synthesis of a geared four-bar mechanism PARLAKTAŞ, VOLKAN; Söylemez, Eres; TANIK, ENGİN (Elsevier BV, 2010-08-01) This paper presents an analysis and synthesis method for a certain type of geared four-bar mechanism (GFBM) for which the input and output shafts are collinear. A novel analysis method is devised, expressions for the transmission angle are derived and charts are prepared for the design of such mechanisms. It is observed that the GFBM considered is inherently a quick-return mechanism. Large time ratios can be obtained with acceptable force transmission characteristics. During the working stroke, approximatel...
TRANSMISSION OPTIMIZATION OF RIGHT-ANGLED 4-BAR MECHANISMS Söylemez, Eres (Elsevier BV, 1993-07-01) Design of spatial four-bar mechanisms in which the skew crank axes are at right angles is investigated. Using an algebraic approach, the lengths of the moving links are expressed as functions of a single parameter. Transmission optimization of right-angled four-bar mechanisms can then be determined from the solution of a single parameter constrained optimization problem. When the motion is symmetric, mechanism proportions which yield constant force transmission characteristics can be obtained.
Implementation of physical boundary conditions into computational domain in modelling of oscillatory bottom boundary layers Tiğrek, Şahnaz; Yılmaz, Bilgi (Wiley, 2010-11-30) This paper discusses the importance of realistic implementation of the physical boundary conditions into computational domain for the simulation of the oscillatory turbulent boundary layer flow over smooth and rough flat beds. A mathematical model composed of the Reynolds averaged Navier-Stokes equation, turbulent kinetic energy (k) and dissipation rate of the turbulent kinetic energy (epsilon) has been developed. Control-volume approach is used to discretize the governing equations to facilitate the numeri...
OPTIMUM DESIGN OF FRAMES ERBATUR, F; ALHUSSAINY, MM (Elsevier BV, 1992-12-03) In this paper optimum design of frames is discussed. Specifically, minimum weight design of steel frames in the elastic range of material behaviour is treated. The solution algorithm is designed and programmed for use on micro-computers to suit a design office environment. Stress and slenderness constraints are considered, however displacement constraints may readily be implemented. Three examples are given and the results are discussed.
Nonlinear dynamic modeling of gear-shaft-disk-bearing systems using finite elements and describing functions Maliha, R; Dogruer, CU; Özgüven, Hasan Nevzat (ASME International, 2004-05-01) This study presents a new nonlinear dynamic model for a gear-shaft-disk-bearing system. A nonlinear dynamic model of a spur gear pair is coupled with linear finite element models of shafts carrying them, and with discrete models of bearings and disks. The nonlinear elasticity term resulting from backlash is expressed by a describing function, and a method developed in previous studies to determine multi harmonic responses of nonlinear multi-degree-of-freedom systems is employed for the solution. The excitat...
