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。 -
