Research on the fracture evolution law and combined bearing structure load of shallow buried coal seam group [PDF]
, 2023 The high-intensity mining of shallow-buried coal seams leads to the fracture of the bearing strata to form a combined bearing structure, which complicates the distribution of cracks in the overlying rock and causes serious damage to the surface. In order

, 2018 大型绣花机的工作部件集中在一个无支撑约束的大跨度横梁上,机架整体结构的刚度提升对横梁基频提升的贡献较小,现有的机架设计通过在横梁上增加桥接子结构以提升机架整体固有频率;桥接子结构的多少和在横梁上的位置成为提高固有频率的关键因素,其模态应变能的分布反应了该模态下的刚度状况。文中对工作频率附近的模态应变能进行加权综合作为灵敏度参数,确定桥接结构的位置并讨论桥接结构个数对整体结构固有频率的影响;所提出的方法能为桥接结构的位置与个数设计提供理论依据 ...
