摘要:

压力容器无量纲设计法可以代替传统设计方法,它能够简化设计过程、减少设计工作量.在归纳压力容器现行设计方法的基础上,给出无量纲化设计法的原理和步骤.通过引入尺寸基准和压力基准的方式,构造两类无量纲参数即相对计算压力和相对尺寸,在设计过程中,使相对计算压力成为主要设计因素.利用该方法,对压力容器主体几种典型结构进行计算分析与无量纲转化,获得圆柱形筒体、球形封头、卡箍紧固结构的无量纲转化公式,完成设计开发阶段的重要内容,为应用无量纲设计法奠定了基础.

Abstract:

The non-dimensional design method of pressure vessels may simplify the design process and reduce the workload, and can be substituted for the traditional method. The theory and steps of the non-dimensional design method were presented based on the present design methods. For this method, two kinds of non-dimensional parameters were constructed through introducing fiducial dimensionand pressure, of which the comparative computing pressure would be the main factor. According to NDDM, several typical structures of the main parts were  analyzedand translated. The non-dimensional formula of the cylindrical shell, hemisphericalhead and fastener structure were obtained. The important contents in the developing step were also finished, which were the basis of the NDDM application step.

Key words: pressure vessels; design method; non-dimensional parameters;  typical structures
