设备综合健康状态评价对提高制造系统的稳定性具有重要意义,文章以特征参数作为失效依据,建立了设备多特征参数运行状态评价模型,阐述了设备健康指数的内涵,通过对健康指数的定量表征评判设备综合运行状态的优劣;在此基础上,运用高斯‐牛顿迭代法建立时间与设备健康指数之间的非线性映射关系模型,求解并预测设备的健康状态以及维护时间节点。最后通过实例验证了该方法的可行性与有效性。
設備綜閤健康狀態評價對提高製造繫統的穩定性具有重要意義,文章以特徵參數作為失效依據,建立瞭設備多特徵參數運行狀態評價模型,闡述瞭設備健康指數的內涵,通過對健康指數的定量錶徵評判設備綜閤運行狀態的優劣;在此基礎上,運用高斯‐牛頓迭代法建立時間與設備健康指數之間的非線性映射關繫模型,求解併預測設備的健康狀態以及維護時間節點。最後通過實例驗證瞭該方法的可行性與有效性。

Evaluation of equipment comprehensive health status is of great significance to improve the stability of manufacturing system .The multiple characteristic parameters evaluation model of equip‐ment operating state was established based on the characteristic parameters .The connotation of health index was elaborated and the comprehensive operating state of equipment was evaluated by quantifying the health index .On this basis ,a nonlinear mapping relation model between time and equipment health index was established based on the Gauss‐New ton iterative method to predict equipment health state and time nodes of maintenance .Finally ,the feasibility and effectiveness of this method was veri‐fied by an example .
