摘要: 滾動(dòng)軸承作為機(jī)械設(shè)備最基本的零件之一,其振動(dòng)信號(hào)具有非線性、非平穩(wěn)的特點(diǎn),針對(duì)這一特點(diǎn),提出了變分模態(tài)分解(variational mode decomposition,VMD)和蝗蟲(chóng)優(yōu)化算法(grasshopper optimization algorithm, GOA)與長(zhǎng)短期記憶網(wǎng)絡(luò)(long short-term memory,LSTM)相結(jié)合的滾動(dòng)軸承剩余壽命預(yù)測(cè)方法...
