自定心结构瓷套胶装机

Dianci bileiqi, 1990
图1为我厂LW6系列高压断路器瓷套（括号尺寸为不同规格）,其特点是精度要求较高,瓷套的形状和位置公差要求较严,一般的胶装方法很难达到图纸要求。国外（如日本、法国）及国内个别单位采用划线找正的办法进行胶装,此法效率较低,且对工人本身的技术素质要求较高,劳动强度也大。80年代我们曾对这类瓷套的胶装设计并制造过一种胶装机（本刊1988年第6期曾作过介绍）。该机经醴陵电瓷厂几年来的使用 ...

谐波微弱信号特征的方差曲线周期识别法

Zhendong Ceshi yu Zhenduan
针对随机因素和微弱信号初相位影响的问题，构造了强噪声背景下检测谐波微弱信号频率、相位的方差曲线周期识别法。首先，基于随机Melnikov函数和系统关于相位分岔图的周期特性，初步提出周期识别法；其次，论证分岔图和方差曲线具有一致性，进一步将周期识别法优化为方差曲线周期识别法；然后，基于频谱泄露最小原则，设计自适应离散傅里叶变换数据处理方法来解决由方差曲线不光滑而引起的结果不准确问题；最后，采用二次检测来解决检测系统中策动力信号与被测信号存在频差而导致动力学转迁的不明显问题。仿真结果表明 ...
