Free Vibration Analysis of Functionally Graded Plates with Multiple Circular and Non-circular Cutouts
graded materials rectangular/skew/trapezoidal/circular plates
2011/8/5
Cutouts are inevitable in structures due to practical consideration. In order to investigate the free vibration of functionally graded plates with multiple circular and non-circular cutouts, finite el...

An experimental study of three different cross-sections (circular, semicircular and rectangular) of micro heat pipes having same hydraulic diameter (D = 3 mm) is carried out at three different inclina...
利用信号non-circular特性的信源个数检测算法
信号检测 最小描述长度准则 阵列信号处理
2009/5/31
在non-circular信号的情况下，提出了信源个数检测算法．通过使用non-circular信号椭圆协方差不为零的特点将可利用阵元个数加倍，并利用酉变换将快拍数加倍，提高了数据协方差矩阵的估计精度，在此基础上改进了信息论检测准则．仿真实验表明新算法具有收敛速度快、角度分辨力高和可检测信号个数多等优点．
偏心齿轮—非圆齿轮行星系分插机构运动机理分析（Analysis of Kinematic Principle of Transplanting Mechanism with Eccentric Gears and Non-circular Gears）
高速插秧机 旋转式分插机构 偏心齿轮—非圆齿轮
2009/5/22
简述了一种旋转式行星系分插机构，用于高速水稻插秧机前插式作业。分析了偏心齿轮-非圆齿轮行星系分插机构的工作机理和结构特点，建立了该机构的运动学模型。基于Visual Basic6.0开发了该分插机构辅助分析与优化软件，通过人机交互方式，优化出满足高速插秧机插秧要求的结构参数为e=3mm, R=19mm,α0=-40°,φ0=36°, S=155mm, H=180mm。
