中文摘要: |
为了解决铸铁烘缸承压元件椭圆形人孔盖设计计算的困扰,设计人员基于国内规范结合ASME规范寻求一种新
的设计计算方法,即利用ASME规范提供的数表找到适合于铸铁烘缸人孔盖材料的特性曲线,将此特性曲线提供的特性
数值代入已经成熟的算例当中,从而计算出人孔盖的承压能力。此方法一旦成熟可以解决椭圆形人孔盖设计计算的难
题,使铸铁烘缸人孔盖的设计进一步的优化 |
英文摘要: |
ln order to solve the problems of design and calculation of the oval manhole covers which cast iron dryers
pressured element, design personnel based on domestic standard and ASME specification sought to find a new design and
calculation method. That was using ASME specification providing the charts to find the characteristic curves suitable for
cast iron manhole covers material.and to find features of the characteristic curves into the numerical example. And then
the bearing capacity of cast iron manhole covers was gotten. Once this method can eliminate the design and calculation
problem of elliptic manholes cover . and the design of cast iron manhole covers can be optimized. |
