基于油液光谱分析的综合传动状态监测试验研究

Test Research on State Monitor of PSST by Oil Spectrometric Analysis

通过对某履带装甲车辆综合传动的液压润滑油液进行长期光谱跟踪监测分析,结合其内部摩擦副的材料分析,根据油液中磨损金属颗粒的浓度趋势分析,判断综合传动磨损状态,确定是否存在故障隐患,从而避免重大故障的突发,为装甲车辆实现视情维修提供理论和试验依据,提高了我军装备的可靠性和可维修性。试验研究证明,此方法具有很高的稳定性和准确性,能够有效地应用于动力传动系统的状态监测及故障诊断。该方法突破了我军装备的定期维修模式而向视情预防维修模式的转变,具有重要的使用价值。

Through the hydraulic lubrication oil spectrometric analysis, we monitored the state of the power-shift steering transmission （PSST） equipped on the track armored vehicle for a long time. Combined with the friction material analysis inside the PSST, based on the concentration analysis of the wear and tear particle inside the oil, the authors estimated the wear and tear state of the PSST and judged if the PSST had the fault hidden trouble. So we can avoid the serious fault, provide the academic and actual basis for RCM and enhance the dependability for the track armored vehicle. The result of examples proves that the characteristic parameter of oil spectrometric analysis has very high stability and veracity. This method has proved effective in fault diagnosis based on oil spectrometric analysis on multifarious power-transmission systems in our army. This method is a breakthrough of the traditional maintainance model and has great useful military values.
