【摘要】 随着科技的发展，高压容器在国民经济中占有越来越重要的地位。但是，目前高压容器普遍存在着经济性较差的问题。本文在分析现有高压容器设计技术的基础上，提出了优化设计与分析设计二者结合的思想，以期达到降低高压容器成本的目的。 本文以涿鹿高压气瓶厂在用柱形蓄势器作为考察对象。通过对其进行应力强度评定，发现原有蓄势器经济性较差。为了解决这一问题，首先利用优化设计方法对其主体尺寸及某些局部区域进行优化，得到相应结果；之后利用分析设计法对优化后的蓄势器进行应力强度评定以确保其安全性。结果表明：在满足安全性及容积基本不变的条件下，柱形蓄势器的重量减少13.97％，节约材料1.58吨，从而降低了制造成本。 利用AutoCAD绘图软件，绘制了优化后的柱形蓄势器的工程图纸。更多还原

【Abstract】 With the developments of science and technology, high pressure vessel plays a more and more important role in national economy. However, there is a common problem of bad economy in high pressure vessel. In this paper, based on analyzing the existing design technology of high pressure vessel, a method of combining the optimal design with design by analysis is presented, in order to reach the aim of cutting high pressure vessel cost. In this paper, the being used cylinder accumulator in ZhuoLu High Pressure Gas Cylinder Factory is selected as study object. By assessing its stress intensity, it is found that the accumulator has high cost. In order to .solve this problem, a study on optimal design of its main dimensions and some local regions is carried out and the corresponding results are obtained. Then, using the method of design by analysis, an assessment of stress intensity on the optimal accumulator is done in order to ensure its safety. The results have shown that with good safety and given volume, the weight of accumulator has decreased 13.97 percent, and the material has saved 1.58 ton, so the manufacturing cost has greatly cut down. By means of AutoCAD software, a project drawing of optimal cylinder accumulator is plotted.更多还原
