为准确掌握道岔转换设备的工作状况,及时预测其故障趋势,真正实现"状态修",提出一种基于道岔转辙机动作功率曲线关联分析道岔故障的方法.以高速铁路用S700K交流道岔转辙机典型动作功率曲线为例,从道岔转辙机典型动作功率曲线类型、道岔故障关联分析2方面,阐述基于道岔转辙机动作功率曲线关联分析道岔故障的总体思路,道岔转辙机动作功率曲线的提取、数据压缩及相关性分析.结果表明:该方法能够指导关联分析道岔故障,提高实际的道岔检修质量,减少维修成本,为实现"状态修"提供数据支撑.该方法不仅是工程可行的,而且具有良好的应用推广价值.%Aiming at the problem of mastering working status of turnout switch machine accurately, predicting the tendency of turnout fault timely, realize "repairing for status" really, brings forward one kind of the method of association analysis which is based on action power curve of turnout switch machine. Taking typical action power curves of S700K alternating turnout switch machine as example, this paper discussed the method from 2 aspects which were distribution of type of action power curve of turnout switch machine and association analysis of turnout fault firstly, and described extracting, data condensation and association analysis of the action power curve of turnout switch machine deeply. Result is indicated, this method is able to guide the association analysis of turnout fault successfully, can rise quality of actual check and repair, lessening design risk, cut down cost of repair thereby, and providing the data sustain of "repairing for status". The method is result to be project feasible, it had fine application extension value also.
