【摘要】 本文引入载荷分布函数使复合载荷依单参数变化,并选取平均挠角作为单一的位移摄动参数,给出了在均布载荷和中心集中力联合作用下边缘固定夹紧的圆薄板大挠度问题的摄动解,并讨论了中心点挠度为零的特殊情况.更多还原

【Abstract】 By means of the perturbation method, this paper presents an approximate solution for large deflection of clamped circular plate under uniform pressure together with a concentrated load at the center. The special case of vanishing central deflection is also discussed, in this paper, a load distribution function is introduced so as to make the compound loads depend on a single load parameter, and average angular deflection is being used as the single displacement perturbation parameter.更多还原
