TAILIEUCHUNG - Design, control, and prototyping of a series elastic actuator for an active knee orthosis

The use of elastic elements in actuators can be effective in improving their performance. The present paper examines the different layouts of the elastic element in actuators, choosing the appropriate design, and then designing a series elastic actuator for use in an active knee orthosis. | Design control and prototyping of a series elastic actuator for an active knee orthosis Engineering Solid Mechanics 6 2018 241-252 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Design control and prototyping of a series elastic actuator for an active knee orthosis Alireza Vadiatia Ahmad Bagheria Mohammad Mahjooba b and Mohammad J.

The Received 10 January 2018 present paper examines the different layouts of the elastic element in actuators choosing the Accepted 10 May 2018 appropriate design and then designing a series elastic actuator for use in an active knee Available online orthosis. For this purpose the design elements of actuators were extracted using the knee data 10 May 2018 Keywords for walking. In the next step considering the effect of the spring stiffness on the energy Series elastic actuator consumption and actuator s peak power its optimum amount for gait was calculated. Active knee orthosis Afterwards the effect of adding the spring has been shown at an optimal value. Since the Energy consumption human knee in a gait cycle involves position and force control designing an efficient controller Peak power to track the force and position of the knee during the gait cycle is the next section of this study. Optimization Due to the specific application of this actuator its volume and size are important for the user. For this reason it is necessary to design and construct an actuator with a suitable size and weight with good output. For this purpose a lightweight and low volume actuator was fabricated. 2018 Growing Science Ltd. All rights reserved. 1. Introduction War accidents illness and .
