一类弹性体的故障检测

DETECTING THE FAULTS OF ONE CLASS OF ELASTIC OBJECTS

针对某种弹性体上有一段不易量测横向位移造成的故障检测困难问题 ,首先给出其参数辩识模型 ,然后导出该模型存在最优参数的必要条件 ,并运用最速下降法归纳出检测这类弹性体故障的具体算法 .最后利用这一算法 ,以深水采矿吸管为对象 ,借助计算机编程 。

As one class of elastic objects is not easy to measure in one segment,it is impossible to detect its faults.First,this paper gives out a parameter identification model of the problem,then concludes th e necessary conditon in which the optimal parameter of the model exists and sums up the algorithm for detecting the faults in detail by making use of a gradient method,Finally,the mining pipe as an example,solved with the help of a computer program,is discussed.
