The equine distal forelimb is a common location of injuries related to mechanical overload. In this study, a two-dimensional model of the musculoskeletal system of the region was developed and applied to kinematic and kinetic data from walking and trotting horses. The forces in major tendons and joint reaction forces were calculated. The components of the(More)
The motion planning for a bipedal robotic gait is studied in this paper in the light of its underactuated nature. The generation of motion trajectory and the corresponding actuation command for an underactuated mechanism is a challenging problem, especially when it is required to needs to satisfy a set of equalities forming kinematics constraints. Existing(More)
REASONS FOR PERFORMING STUDY The mechanical environment of the distal limb is thought to be involved in the pathogenesis of many injuries, but has not yet been thoroughly described. OBJECTIVES To determine the forces and moments experienced by the metacarpus in vivo during walking and also to assess the effect of some simplifying assumptions used in(More)
Commonly, operational aspects of an industrial process are not included when evaluating the process environmental performance. These aspects are important as operational failures can intensify adverse environmental impacts or can diminish the chance of making any amelioration. This paper proposes to include these operational aspects by applying a method(More)
Forces exerted at the joints of the equine distal forelimb play a major role in common injuries of the region. In this study, a two-dimensional musculoskeletal model was developed to calculate the reaction forces at the joints of the distal forelimb from measured kinematic and kinetic data during walking and trotting. The reaction forces due to muscle-(More)
Prestresses are purposefully added to an object to improve its performance, such as tuning a guitar string by adding tension. This paper reports how the normal modes of a sheet metal component can be tuned through the prestresses generated by cold-forging small dimples. Finite element analysis showed that the frequencies of specific mode shapes were(More)
OBJECTIVE To assess the net mechanical load on the distal end of the third metacarpal bone in horses during walking and trotting. ANIMALS 3 Quarter Horses and 1 Thoroughbred. PROCEDURES Surface strains measured on the left third metacarpal bone of the Thorough-bred were used with a subject-specific model to calculate loading (axial compression, bending,(More)
