Abstract : based on the analysis of the main failures discovered in pavement on steel deck plate and the demanding service condition of the pavement on steel deck, high - temperature rutting test, low - temperature bending test and controlled stress flexural fatigue test are used to study the performance of asphalt mixtures modified by epoxy resin including high - temperature stability, low - temperature cracking - resistance, and fatigue cracking - resistance, which are served to evaluate the modification effect of epoxy resin of different contents. with the addition of epoxy resin, all the three performances are improved greatly. however, when the amount of epoxy resin added is over a certain value, the modification effect will be stable with no extra benefit detected. finally, in terms of the properties of the three respects, 20 ?, 30 ?, 30 ? are given separately as the proposal adding contents
文摘:在分析鋼橋面鋪裝層主要病害和特殊工作環境的前提下，分別採用高溫車轍試驗、低溫小梁彎曲試驗和控制應力小梁彎拉疲勞試驗，研究了不同環氧樹脂摻量下的環氧樹脂改性瀝青混合料的高溫穩定性、低溫抗裂性和抗疲勞性能.試驗結果表明:環氧樹脂對這3個方面都有很大的改進效果，但改性效果和樹脂的添加量並不是一個無限遞增的關系，當添加量超過一定數值以後，改性的效果將趨于平穩.最後就高溫、低溫、疲勞3個方面分別提出環氧樹脂添加量為20 ? ， 30 ? ， 30 ?的建議值 -

In practical application, the m10 180 bolts, which are installed in the head cover of the torque divider of ts5560 special automobile, sometimes fracture all of a sudden. according to the tests of acceleration, stress and strain, and the exciting test, it is resonance vibration that leads to the compound - bending fatigue fracture of the bolts. the exciting force caused by drive system, transmitted through the torque divider, produces a 1000 - 1500hz cyclical excitation at the junction of the bolts and head cover, which causes the first order bending resonance vibration of the bolts
通過加速度、應力應變測試實驗和激振試驗的研究，發現ts5560特種車分動器取力器氣缸端蓋m10 180螺栓斷裂問題是由於共振引起的雙向彎曲疲勞斷裂：傳動系統工作所產生的激勵，經過分動器結構的傳遞（特別是分動器一階扭轉模態的放大） ，在螺栓的連接處產生1000 1500hz的振動激勵，其導致螺栓一階彎曲共振，在螺栓一階彎曲模態的阻尼比較小的情況下，使得螺栓產生較大的共振響應，導致螺紋處的彎曲動應力較大，疲勞壽命較低。 -
