| The Probability Distribution Law of the Internal Stress on Each Components of Catenary System |
| 摘要 |
| 采用有限元并結(jié)合改進(jìn)算法的徑向基神經(jīng)網(wǎng)絡(luò)RBF，判別接觸網(wǎng)系統(tǒng)各部件內(nèi)部應(yīng)力的隨機(jī)分布規(guī)律。以蘭新線武嘉段接觸網(wǎng)腕臂為算例，把安裝角度、冰負(fù)載、承力索覆冰風(fēng)負(fù)載、接觸線覆冰風(fēng)負(fù)載等參量作為基本變量，按各變量的分布規(guī)律隨機(jī)地產(chǎn)生50組樣本數(shù)據(jù)，通過(guò)有限元計(jì)算出每 |
