摘要
将吊耳的外形及耳环的横截面作了简化,假定吊钩对耳环的横向压力均匀分布。选择了所有可能的机动模型,推导了相应的上限载荷公式,最后作了数值计算。
The configulation of the hanging-ear and its cross section are both simplified. The lateral pressure from the hook is assumed to be uniformly distributed. All possible kinematical models are choosen, and the corresponding formulas of the upper-bound loads are deduced. At the end the result of numerical calculation is given.
