| 1 | 基于JRD和CUSUM的滚动轴承性能退化状态识别与评估显示文摘退化特征提取是滚动轴承性能退化状态识别和评估的关键,JRD克服了传统特征无法准确反应轴承当前技术状态的不足,但在全寿命阶段上稳定性、单调性差,应用累积和(CUSUM)对其进行改进,从而准确识别和评估轴承性能退化状态。应用小波包变换对原始信号进行降噪;计算不同技术状态下信号的Renyi熵,并对比与标准状态的相似程度得出JRD值,作为滚动轴承退化状态特征;应用CUSUM增强JRD值对于寿命微弱变化的敏感性及轴承全寿命的单调性。通过试验验证,滚动轴承性能退化状态的识别率能达到100%,同时能够分阶段、单调性地评估轴承性能退化状态。 | 夏均忠 吕麒鹏 陈成法 刘鲲鹏 郑建波 | 2019 | 振动与冲击2019，38，2： | 8 |
| 2 | 基于MD-CUSUM和TD-SVR的滚动轴承健康状态预测显示文摘故障特征提取是轴承健康状态描述的关键,然而当前常用方法提取的特征往往维数较高或信息缺失,无法单调性地反应轴承健康状态,且预测结果不能有效反应轴承退化趋势。应用累积马氏距离(MD-CUSUM)实现特征降维并得到健康指标(HI),能够在低维层面上单调性地反应轴承健康状态;构建时滞性支持向量回归(TD-SVR)模型,提高滚动轴承健康状态预测精度。通过试验数据分析对比了MD-CUSUM与等距特征映射(ISOMAP)的优劣,结果表明MDCUSUM和TD-SVR相结合在轴承健康状态预测方面具有更好地效果。 | 夏均忠 吕麒鹏 陈成法 刘鲲鹏 郑建波 | 2018 | 振动与冲击2018，37，19： | 7 |
| 3 | Clinical outcomes of management of posterior capsule rupture with air bubble techniques显示文摘AIM:To introduce a new surgical technique,air-bubble technique for the management of posterior capsule rupture(PCR)and to evaluate the safety and efficacy of the technique.METHODS:A retrospective case series analysis of 24 eyes of 24 patients,in which the air bubble technique was used for the management of PCR,was performed.Once PCR occurred,a dispersive ophthalmic viscosurgical device(OVD)was injected into the tear.And small volumes(0.2-0.3 mL)of air bubbles were injected beneath the OVD.The air bubble served as a physical barrier and supported the posterior capsule.RESULTS:After surgery,none of the patients had serious complications during the follow-up period of 1 y.Extension of the PCR size occurred in only 2 cases,and additional OVD injection was required only in 3 cases.Air bubbles imparted great stability to the nuclear pieces and the posterior capsule.CONCLUSION:The air-bubble technique may be considered a safe and effective procedure for managing a PCR.It may be of value to the inexperienced cataract surgeon. | Jongyeop Park Seungwoo Lee Jinhyun Kim | 2020 | International Journal of Ophthalmology(English edition)2020，13，12： | 1 |
