A novel fully-integrated miniature six-axis force/torque sensor

This paper presents a new designed miniature six DOF （degree of freedom） force/torque sensor. This sensor is fully integrated with a micro DSP （digital signal processor）, so all the signal conditioning, A/D, decoupling, digital-signals serial output are performed in the sensor. Some experimental results are presented to demonstrate the capability of the proposed design. Finally, a neural network was used for decoupling the interacting signals, compared with the conventional method using the inverse matrix, this new method is more accurate.

PEAK COVARIANCE STABILITY OF A RANDOM RICCATI EQUATION ARISING FROM KALMAN FILTERING WITH OBSERVATION LOSSES

We consider the stability of a random Riccati equation with a Markovian binary jump coefficient. More specifically, we are concerned with the boundedness of the solution of a random Riccati difference equation arising from Kalman filtering with measurement losses. A sufficient condition for the peak covariance stability is obtained which has a simpler form and is shown to be less conservative in some cases than a very recent result in existing literature. Furthermore, we show that a known sufficient condition is also necessary when the observability index equals one.

W_(18)Cr_4V钢真空油淬白亮层、熔化层形成原因的试验研究

W_(18)Cr_4V钢真空加热油淬后,表面出现白亮层和熔化层等异常现象。本文利用金相显微镜,显微硬度计、扫描电子显微镜和电子探针等手段对白亮层和熔化层进行了分析研究。试验表明,白亮层、熔化层均是真空油淬增碳的结果。本文对白亮层、溶化层形成原因进行了比较深入的分析探讨提出了产生白亮层必须同时具备的三个条件。     

中碳钢退火孪晶的形态及形成机制

利用光学显微镜对中碳钢退火孪晶的形态及形成机制进行了研究。退火孪晶是中碳钢过热组织的特征之一。其形态分穿晶型和中止型，分别按横向、纵向机制形核长大。退火孪晶有利于晶粒细化     

应用测力—落刀装置对积屑瘤、鳞刺的研究

本文研制了一种测力—落刀装置,对积屑瘤和鳞剌的某些问题进行了试验研究。结果表明:在积屑瘤存在的区域内,由于刀具实际前角的增加,以及切屑与积屑瘤的接触长度小于自然接触长度,从而导致了切削力的降低。积屑瘤不是整体稳定不变的,也不是高频地整体脱落后再重新生长。而是基体比较稳定,头部产生高频的分裂、成长,其分裂的部分留在工件表面成为鳞剌,同时,引起了切削力的较大波动。切削力动态分量越大,相应的鳞剌高度越高。     

西酞普兰与舒乐安定治疗广泛性焦虑临床研究对照

目的比较西酞普兰与舒乐安定的抗焦虑效果和副作用.方法符合CCMD-3广泛性焦虑诊断标准60例,随机分为研究组(西酞普兰组)与对照组(舒乐安定组);用汉米尔顿焦虑量表(HAMA)评定症状变化,用TESS评定副反应,疗程6周.结果研究组显效率76.67%,有效率93.33%;对照组显效率73.33%,有效率90.00%,两组疗效无显著差异.研究组副作用有恶心、口干、嗜睡、头痛、便秘,以头痛、呕心、口干为最常见的不良事件.结论西酞普兰治疗广泛性焦虑效果较好,副反应轻.
