金属阻尼材料阻尼本领试验方法扭摆法和弯曲共振法 - The testing method for internal friction of fine ceramics at elevated temperatures - part 2 : flexural resonance method
细陶瓷的高温内部摩擦试验方法.第2部分:弯曲共振法 - 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
通过加速度、应力应变测试实验和激振试验的研究，发现ts5560特种车分动器取力器气缸端盖m10 180螺栓断裂问题是由于共振引起的双向弯曲疲劳断裂：传动系统工作所产生的激励，经过分动器结构的传递(特别是分动器一阶扭转模态的放大) ，在螺栓的连接处产生1000 1500hz的振动激励，其导致螺栓一阶弯曲共振，在螺栓一阶弯曲模态的阻尼比较小的情况下，使得螺栓产生较大的共振响应，导致螺纹处的弯曲动应力较大，疲劳寿命较低。
