Experimentation results indicate that the singularity of the fault machinery vibration signal can be detected and the machinery fault can be discovered by the system. 試驗表明，系統可以發(fā)現故障機械振動(dòng)信號帶有的奇異性，實(shí)現旋轉機械的故障診斷。
It specifies the establishment of the kinematic equations and the Jacobin matrix.It also gives a detailed discussion on the singularity of the mechanism. 文章具體闡述該操作臺的運動(dòng)學(xué)方程和雅可比矩陣的建立過(guò)程，并詳細討論了機構的奇異性。
