This study proposes a novel robotic hand that can achieve self-adaptive grasping and large payload (over 20 kg) with single actuator. Accordingly, two mechanisms, an actuation system self-motion switching finger self-locking mechanism, are installed in 1-degree-of-freedom hand. The switches the output motion from translational to rotational according applied external load. is bent by inserting ...

This presentation investigates Active Structural Acoustic Control (ASAC) of rotating machinery with high modal density, by placing actuators as close as possible to the noise source. For this purpose, an experimental set-up has been built, as discussed in [3]. The set-up consists of a shaft supported by two bearings, of which one is made “active” by mounting piezo-actuators around it, to influe...

In this paper, a mathematical model of rotor-bearing system is presented. The includes modal elastodynamics flexible rotor as well the in-plane radial dynamics bearing with outer race. Elastodynamics shaft utilises solution based on Green's function to provide computationally efficient approach. race modelled using Timoshenko beam theory. also detailed lubricated contact mechanics balls-to-race...

The authors present a comprehensive review of the literature emphasizing the use of flexible intramedullary nails in the treatment of fractures in children, focusing the treatment of femoral shaft and forearm fractures and emphasizing the importance of the non-surgical approach. Children's age and weight threshold are not well defined for the use of the method. The removal of implants is a cont...

The bacterial flagellum is a motile organelle driven by a rotary motor, and its axial portions function as a drive shaft (rod), a universal joint (hook) and a helical propeller (filament). The rod and hook are directly connected to each other, with their subunit proteins FlgG and FlgE having 39% sequence identity, but show distinct mechanical properties; the rod is straight and rigid as a drive...

To keep the diversity of antibodies in artificial immune system evolution process, this paper puts forward a kind of increase simulation surname inheritance algorithm based on the clonal selection algorithm, and identification and forecast the Vibration Data about CA6140 horizontal lathe machining slender shaft workpiece prone. The results show that the algorithm has the characteristics of flex...
