摘要
根据平面曲梁理论,结合详细的截面内力Nφ、Qφ、Mφ的推证所得公式,推导出了提升容器悬挂装置耳孔设计的曲梁理论计算公式,并举例对比了新公式与拉密公式计算结果,具有较强的实践指导作用。
The theorytical formaltion to assist in design earhor of suspension device in the elevate container is deviced from the theory, of plane bend beam and combine with internal stress Nψ, Qψ and Mψ in the cross section in this paper,and makes a comparision between the new formula and the Lame - formula by way of example. It proved that the new formula can supply a guide to the prative.
