This method selects two parameters, energy and variance, as the characteristic parameter of trolley track, and successfully in extracts the feature frequency belt of trolley track vibration. Furthermore, this technology is applied to practical engineering programs and has good veracity and reliability.2. According to the research of this thesis on the trolley tracks\' present data, the status classification of trolley track with normal distribution is presented. This method divides trolley tracks\' situations into five parts and perfects the classifying method of trolley tracks\' mechanical situation.

具体工作如下；1、将小波包分析方法运用到岸桥小车轨道振动信号的分析中，选取能(来源：A65BC0f论c0文网www.abclunwen.com)量与方差作为轨道的振动特征参数，有效提取出铰点部位与非铰点部位的振动特征频段。2、将正态分布原理引入到岸桥小车轨道铰点机械性能状态的划分之中，并用最大熵概率分布加以验证，准确地反映了实际情况，并定义了正态分布诊断准则的状态分级评价的原则和临界点，方便和简化了状态判断的决策过程。
