Defterli, Sinem Gözde
In this study, a biomechanical horse rider model is developed. The rider is modeled, on the sagittal plane, using link segments representing the limbs of the body. The model which is a tree type structure kinematically, consists of 11 links connected by the revolute joints. Assuming that each of the joints is actuated by an equivalent muscle torque, the equations of motion of the rider model is developed. In this study, it is assumed that the actuating muscle torques applied by the rider and the equivalent forces applied by the horse on the rider are to be minimized. An appropriate performance measure is defined in order to achieve this goal. This performance measure is minimized subject to the biological constraints regarding the movement and torque limits of a human joint. A constraint, which ensures that the rider does not fall down from horseback, is also imposed. As two case studies, sitting trot and a sudden stop scenario are considered. Computer codes are developed, in MATLAB®, in order to realize these case studies.

Deveci, M; Eski, M; Gürses, Senih; Yucesoy, CA; Selmanpakoglu, N; Akkas, N (Ovid Technologies (Wolters Kluwer Health), 2004-07-01)
In this experimental study, the goal was to test the sufficiency of actual fixation plates in zygomatic complex fractures and the efficiency of a modified plate at the zygomaticofrontal suture in a suitable model, which was designed for biomechanical study. To address this issue, a zygomatic fracture model produced by using a cadaveric cranium was simulated and the fractures were fixed by the actual and modified fixation materials. The force simulating masseter muscle pull was applied with the Lloyd materia...
Modelling, control and design of a clutched parallel elastically actuated articulated robotic leg through virtual tunable damping
Candan, Sinan Şahin; Tanfener, Emre; Turgut, Ali Emre; Saranlı, Uluç (2020-01-01)
In this study, design, modelling and control of a clutched parallel elastically actuated articulated leg is presented. Clutch mechanism is introduced to disengage the parallel elastic element when it is not needed. Some of the design principles concerning the ease of manufacturing and assembly are underlined. While the system has two joints at hip and knee that can be actuated, for simplicity, restrained motion of the system in vertical direction is considered only with hip actuation. Controller is based on...
Investigation of control of human balance-recovery reactions
Bilgin, Nurdan; Özgören, Mustafa Kemal; Department of Mechanical Engineering (2015)
In this study, a natural control law has been conjectured, which is assumed to be applied by the central nervous system of a human being in order to maintain the erect posture after being exposed to a suddenly occurring impulsive disturbance. The control law is conjectured as PD (proportional-derivative) control, because it has to be compatible with the physiological facts. The conjectured control law has been validated by comparing a set of experimental results with the corresponding set of simulation resu...
Nonlinear Time-Varying Dynamic Analysis of a Multi-Mesh Spur Gear Train
Yavuz, Siar Deniz; Saribay, Zihni Burcay; Ciğeroğlu, Ender (2016-01-28)
The nonlinear dynamics of a multi-mesh spur gear train is considered in this study. The gear train consists of three spur gears, with one of the gears in mesh with the other two. Dynamic model includes gear backlash in the form of clearance-type displacement functions and time variation of gear mesh stiffness. The system is reduced to a two-degree-of-freedom definite model by using the relative gear mesh displacements as the coordinates. The equations of motion are solved for periodic steady-state response ...
Analysis and Control of a Dissipative Spring-Mass Hopper with Torque Actuation
Ankaralı, Mustafa Mert; Saranlı, Uluç (2011-01-01)
It has long been established that simple spring-mass models can accurately represent the dynamics of legged locomotion. Existing work in this domain, however, almost exclusively focuses on the idealized Spring-Loaded Inverted Pendulum (SLIP) model and neglects passive dissipative effects unavoidable in any physical robot or animal. In this paper, we extend on a recently proposed analytic approximation to the stance trajectories of a dissipative SLIP model to analyze stability properties of a planar hopper w...
