A New Contact Force Model for Low Coefficient of Restitution Impact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impact problems arise in many practical applications. The need for obtaining an accurate model for the inelastic impact is a challenging problem. In general, two approaches are common in solving ...
A High Performance Pneumatic Force Actuator System: Part II—Nonlinear Controller Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article we present two nonlinear force controllers based on the sliding mode control theory. For this purpose we use the detailed mathematical model of the pneumatic system developed ...
A High Performance Pneumatic Force Actuator System: Part I—Nonlinear Mathematical Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we developed a detailed mathematical model of dual action pneumatic actuators controlled with proportional spool valves. Effects of nonlinear flow through the valve, air compressibility ...
Eliminating the Reaching Phase From Variable Structure Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a variable structure control method that eliminates the reaching phase. The approach is based on modifying the sliding domain equations through the use of exponential ...
On the Measurement of Dynamic Stability of Human Locomotion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main focus of the present investigation is the development of quantitative measures to assess the dynamic stability of human locomotion. The analytical methodology is based on Floquet theory, ...
Sliding Control Without Reaching Phase and Its Application to Bipedal Locomotion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new variable structure control law based on the Lyapunov’s second method that can be used in trajectory planning problems of robotic systems is developed. A modified approach to the formulation ...
Collision of Two Mass Baton With Massive External Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the solution of the impact problem for a sliding/bouncing baton on flat and inclined planes subject to surface friction. The baton is assumed to have unilaterally constrained ...
Shock Absorption Using Linear Particle Chains With Multiple Impacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we numerically solved the elastic multiple impact problem in a linear chain of balls using the impulse momentum and Hertz contact theory based methods. The first method depends ...
Kinematics and Dynamic Stability of the Locomotion of Post-Polio Patients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study reported in this article was conducted to propose a set graphical and analytical tools and assess their clinical utility by analyzing gait kinematics and dynamics of polio survivors. ...
