Domenico CAMPOLO, Fabrizio TAFFONI, Domenico FORMICA, Flavio KELLER, Eugenio GUGLIELMELLI
《机械工程前沿(英文)》 2011年 第6卷 第1期 页码 82-88 doi: 10.1007/s11465-011-0208-0
This paper describes an interdisciplinary approach to the assessment on infants’ behavior, with a focus on the technology. The goal is an objective, quantitative analysis of concurrent maturation of sensory, motor and cognitive abilities in young children, in relation to the achievement of developmental milestones. An instrumented block-box toy specifically developed to assess the ability to insert objects into holes is presented. The functional specifications are derived from experimental protocols devised by neuroscientists to assess spatial cognition skills. Technological choices are emphasized with respect to ecological requirements. An ad hoc calibration procedure is also presented which is suitable to unstructured environments. Finally, preliminary tests carried out at a local day-care with 12–24 months old infants are presented which prove the in-field usability of the proposed technology.

悬浮光力学是光力学与量子光学结合的产物,为微纳机械振子的控制和测量提供了一种全新的量子方法,这种方法具有前所未有的观测精度,可接近甚至突破标准量子极限,具有广阔的发展和应用前景。目前国际上已在室温下利用此系统实现了力、力矩、位移、加速度等多个物理量的极高灵敏度测量。本文综述了悬浮光力学的研究现状及国内外在精密传感与测量方面的进展。作为近年来发展起来的一种前沿技术,悬浮光力学已逐渐从基础研究走向应用,特别是对惯性传感与精密测量领域有重要的应用前景。最后提出了发展基于悬浮光力学的惯性传感颠覆性技术的建议,为我国惯性传感与量子精密测量技术发展规划的制定提供参考。

三维(3D)打印的软磁结构在工程和材料领域已引起广泛关注和研究。这种结构驱动形状改变的力会导致磁场分布发生变化,表明这种结构具有将机械能转化为电能的能力。在本文的研究工作中,通过整合两种3D打印方法,制造了一种具有柔性超疏水和磁性的器件。3D打印磁性器件(3DMD)在连续滴水时,表现出具有长期稳定的力电转换能力,输出电流比现有文献记录的输出电流高。结合麦克斯韦数值仿真,研究了3DMD的力电转换机理,进而指导了各种参数的调控。此外,通过连续的雨水收集,三个集成的3DMD点亮了一个商用发光二极管(LED)。这种结合了能量转换的组合型设计有望推动 3D打印领域的发展。

《机械工程前沿(英文)》 2015年 第10卷 第4期 页码 311-325 doi: 10.1007/s11465-015-0352-z
The torso plays an important role in the human-like operation of humanoids. In this paper, a method is proposed to analyze the behavior of the human torso by using inertial and magnetic sensing tools. Experiments are conducted to characterize the motion performance of the human torso during daily routine operations. Furthermore, the forces acting on the human body during these operations are evaluated to design and validate the performance of a humanoid robot.

Magnetostriction varieties and stress relief caused by pulsed magnetic field

Magnetostriction is investigated to evaluate the stress relief caused by pulsed magnetic field treatment, because this physical property is closely associated with residual stress. Magnetostriction of different stressed samples is measured in this paper. The stress variations caused by pulsed magnetic treatment are also compared. It is found that magnetostriction variations are closely associated with stress changes. Thermodynamic potential is used to find the relationship between them. Based on several assumptions, we find that the product of magnetostriction amplitude and stress magnitude is nearly a constant during magnetic field treatment, which is valuable for stress relief evaluation and optimizing processing parameters. This conclusion is testified by stress measurements, and the calculated values are in accordance with the experiment results.
