compound exciting 中文意思是什麼
compound exciting
解釋
復勵的-
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。 -
In the third part, taking advantages of the tests of acceleration, stress and strain, the exciting test, and modal analysis method, it is found out that resonance vibration leads to the compound - bending fatigue fracture of the bolts. accordingly, a series improvement measures are proposed
第三章通過對分動器及長螺栓、短螺栓的加速度、應力應變測試分析實驗和激振試驗、模態分析研究，確定螺栓斷裂問題的根源在於共振響應導致疲勞斷裂，並提出了一系列的改進措施。
