针对邮轮上建采用的钢板较薄,且舷侧大开孔密集,结构刚度较弱,在上建吊装过程中容易出现结构或者舾装件损伤的问题,总结邮轮上建分段吊装的评估流程,以一极地邮轮上建分段为例,开展吊装方案设计,并利用有限元对结构应力、分段整体位移与舷侧开孔局部位移进行计算评估,利用线性回归方法对吊装参数进行敏感性分析,结果表明,邮轮上建舷侧结构的局部相对位移评估十分有必要,相对于应力和整体位移,为主控因素,且垂向位移是局部位移评估的主控参量;结构应力与开孔局部位移对吊耳布置更敏感,整体位移对临时补强更敏感。

为了提高机械设备不平衡故障的判断准确率,针对目前振动信号检测分析计算均在服务器云平台进行的现状,设计一种在边缘计算端实现的方式。通过自适应数字滤波方法分析出旋转机械不平衡故障,利用中心频率自适应带通数字滤波器实现噪声去除,并且将算法固化到嵌入式单片机上。通过中心频率带通滤波器,利用数字化滤波器传递函数,对采集的信号数据进行计算分析;同时利用嵌入式单片机采集旋转机械转速信号,让滤波器的中心频率随着转动设备基频变化去除噪声,得到较为准确的不平衡振动信号;最后利用快速傅里叶变换(FFT)提取故障信号频率,进而判断旋转机械动平衡故障。

We report the radio observations of the eclipsing black widow pulsar J1720-0534, a 3.26 ms pulsar in orbit with a low mass companion of mass 0.029 to 0.034 M⊙. We obtain the phase-connected timing ephemeris and polarization profile of this millisecond pulsar(MSP) using the Five-hundred-meter Aperture Spherical radio Telescope(FAST), the Green Bank Telescope(GBT), and the Parkes Telescope. For the first time from such a system, an oscillatory polarization angle change was observed from a particular eclipse egress with partial depolarization, indicating 10-milliGauss-level reciprocating magnetic fields oscillating in a length scale of 5 ×10^(3)km(assuming an orbital inclination angle of 90°) outside the companion's magnetosphere. The dispersion measure variation observed during the ingresses and egresses shows the rapid raising of the electron density in the shock boundary between the companion's magnetosphere and the surrounding pulsar wind. We suggest that the observed oscillatory magnetic fields originate from the pulsar wind outside the companion's magnetosphere.
