本書圍繞數(shù)控磨齒機(jī)可靠性技術(shù)中的一系列問題，在可靠性建模、可靠性評(píng)估、故障分析及可靠性風(fēng)險(xiǎn)評(píng)價(jià)等方面進(jìn)行了研究，以達(dá)到提高國產(chǎn)數(shù)控磨齒機(jī)的可靠性水平的目的。本書首先確定了可靠性評(píng)價(jià)特征量及這些特征量之間的相互關(guān)系，為可靠性評(píng)估方法的研究奠定基礎(chǔ)；其次對(duì)小樣本可靠性評(píng)估方法進(jìn)行了研究，建立了基于 RBF 神經(jīng)網(wǎng)絡(luò)的可靠性評(píng)估流程，同時(shí)對(duì)數(shù)控成形磨齒機(jī)故障和可靠性風(fēng)險(xiǎn)進(jìn)行了綜合分析，為提升機(jī)床裝備可靠性奠定基礎(chǔ)。 本書適合企業(yè)技術(shù)裝備人員閱讀，也可作為高等學(xué)校機(jī)械制造、智能制造相關(guān)專業(yè)在校本科生、研究生的教學(xué)參考用書。
