| 基于神經(jīng)網(wǎng)絡(luò)算法和附加質(zhì)量法的短吊桿張力識(shí)別(31 卷) |
| 英文標(biāo)題 |
| The Tension Identification of Short Hangers Based on Neural Network Algorithm and Additional Mass Method |
| 摘要 |
| 根據(jù)質(zhì)量影響吊桿自振頻率的特性，用附加質(zhì)量法增加識(shí)別參數(shù)，實(shí)現(xiàn)對(duì)短吊桿張力的識(shí)別。隨機(jī)生成吊桿的張力和彎曲剛度，并運(yùn)用有限元方法計(jì)算出對(duì)應(yīng)的附加質(zhì)量前后吊桿的自振頻率，構(gòu)成神經(jīng)網(wǎng)絡(luò)的教師數(shù)據(jù)，訓(xùn)練神經(jīng)網(wǎng)絡(luò)，擬合吊桿的自振頻率與彎曲剛度和張力之間的非線性關(guān) |
