A vibration suppression technique for lightweight and flexible membrane structures is proposed using smart structure technology with a dielectric elastomer actuator (DEA). DEA is a lightweight flexible polynomial material with a large deformation and high response time. Active vibration control for membrane structures with DEAs is examined in this study. To improve the vibration control effect, multiple DEAs are applied. These actuators generate vibration control forces simultaneously during the control. A controller for the active vibration control is designed based on the H∞ control method. The effectiveness of proposed vibration control technique is experimentally validated. |

A Rapid Design Approach for Transverse Flux Machines in Underwater Applications |
Christoph Stoeffler(University of Bremen, Germany) |
Transverse Flux Machines (TFMs) offer new ways of robotic actuation, since they possess relative high torque under low rotational speed. This allows to omit gears what can be advantageous for many applications. Such drives are then called "direct drives". At the same time, it is required that the topology of the electromagnetic machine itself is adapted to its use case. We propose a rapid design approach that couples recent analytical simulation approaches with a genetic algorithm to find optimal motor designs. We believe that such approaches can bring TFMs quicker into new applications.

The goal of this research work is the indigenous development of a Slide Stainer which is economically viable and has sufficient throughput for primary screening of cervical cancer, the most prevalent cancer among women in India.The design of a novel 4-arm Rotary Slide Stainer for cytological study is proposed in this paper. In this design, both the structure and software control systems are developed. The objective was to achieve higher staining efficiency by the simultaneous staining of 96 (24x4) slides in one complete staining cycle, through an indigenous design having the minimum possible footprint. |
