We propose the use of a spring at the knee joint, and the following strategy: store energy in the spring during the whole period in which the knee joint is locked in full

(2001) also showed that the total machining cost per part, assuming only direct costs, consists of three elements: the independent cost on Cs , (part material cost

The motor torque controls the joint angle tracking and decreases the low frequency link vibration, while piezoelectric sensor and actuator are added to control the

As previously predicted by the finite element method, the experimental electrical impedance curve shows that there is a mode coupling between the first thickness mode ( f t =

To achieve this aim, we use the Navier-Stokes equations; the finite volume method; co-located arrangement of variables; segregated solution for the three

The 55%Al-Zn coated steel showed higher yield and tensile strength and lower total elongation and hardening coefficient compared to zinc coated steel and the coating showed

Dynamic Vibration Neutralizers, more often and incorrectly (Crede, 1965) called Dynamic Vibration Absorbers (DVA) are mechanical devices to be attached to
