实时位移是结构健康监测及振动控制所需的重要参数,但固定参考点式位移计法及非接触摄录式位移测量法成本均较高,而加速度二次积分重构位移算法受积分初始条件影响导致误差可控性差。本研究利用arduino开源微控制器平台的开放性和微电子机械系统(Micro-Electro-Mechanical-Systems,MEMS)型加速度计的成本优势,结合内嵌式加速度重构位移Lee算法对积分初值条件的低依赖性特征,开发了一种低成本、加速度和动态位移直接测量系统,并配合内置SD卡模块实现了实时采样、数据存储功能。基于小型振动台对比实验,验证了该系统对简谐振动、地震动加速度、桥梁墩顶横向位移测量的有效性和精度。结果表明:地震动加速度激振下,该系统与成熟加速度测量系统峰值误差低于7%;实测桥梁墩顶横向位移激振下,该系统与线性可变差动变压器式相对位移计(Linear-Variable-Differential-Transformer,LVDT)最大测量误差低于10%。

In this research, two DoF five bar robot manipulator is controlled by using a human-machine interface program working in a computer. The human machine interface program is developed in Visual C#. Net environment after completing inverse kinematic analysis of the robot manipulator. Human machine interface in computer screen calculates two rotational joint variables for given positions of the robot end point. Then the computer program sends a data package containing these joint variables to arduino microcontxoller. arduino microcontxoller set the position of two servo motors according to calculated joint angles. Any position in workspace can be obtained by using the algorithm. The robot can follow traj ectories such as a line, a circle and a rectangle. Furthermore, a lot of patterns can be generated using function with variable radius and angle of rotation.

利用三轴线性霍尔传感器MLX90393制作磁记忆检测探头,基于arduino硬件开发平台研制金属磁记忆检测系统,以30CrMo材料试件为试验对象,在静载拉伸作用下开展金属磁记忆试验研究,分析磁记忆信号变化规律以及磁记忆信号梯度值与拉伸载荷之间的变化特征。实验结果表明,拉伸过程中试件表面的磁记忆信号切向分量梯度最大值在拉伸载荷达到16 kN时开始明显变化,在23 kN之后急剧增大到0.042 5;法向分量梯度最大值在拉伸载荷达到23 kN之后急剧增大到0.55。本系统为铁磁性材料中应力集中的判定和测量提供了一种有效的检测方法。

针对arduino支持递归调用及栈溢出隐患问题,设计了安全递归调用算法。在该算法中,每次递归调用前探测剩余内存并记录递归调用的深度,在内存不足以进行下一次递归调用时给出递归调用过深告警及最大递归调用深度提示,并安全返回。以斐波那契数列、汉诺塔等典型的递归调用问题为实验对象,在分析其递归调用栈溢出风险的基础上,采用这种算法在arduino中进行了安全递归调用验证。针对栈溢出和非溢出典型场景进行测试均可正常工作,验证了安全递归调用算法的有效性和实用性,从而进一步增强arduino应用潜能。

Part of the difficulty in engineering education is to achieve aggregate theoretical knowledge to practice what therefore discourages the student. Trying to alleviate this difficulty, practical problems are created to encourage students to apply their knowledge in different ways; these problems can be computational order, resolved by programs through simulation, or physical, with the realization of models, prototypes, benches or interactive platforms with visual practical approach. From this, it was proposed to students of the Federal University of Pardi--Campus Tucurui through the Electric Power Systems and Mechanics Research Group, in order to apply knowledge arising from multidisciplinary fields of engineering in the construction of a prototype with reused materials and low cost enabling studies and analysis of vibrations in unbalanced motors. This system features an open source prototyping embedded platform arduino to read values from the sensors used： accelerometers and potentiometers coupled to the engine, aiming to collect values and vary the supply voltage. The results are read by arduino and computationally processed to be printed on an LCD display. Therefore, the aim of this is to provide an accessible way using simple techniques a prototype linking the theoretical and practical knowledge as the system of the bench that performs vibration analysis in an unbalanced motor interactively, and encourage research and development technologies in the Amazon region.
