Optimization design of discontinuous zone of pressure vessels based on the quasi-equal strength criterion 准等强度原则下压力容器不连续区的优化设计
The vibration amplitude model with single resonance quasi-equal difference was given. 提出了单谐次准等差振幅模型。
Under the condition of quasi-equal level condition, density distribution of homogeneous layers are conflict with the real Earth density distribution. 在参数椭球的准等位条件下,匀质分层的密度分布并不符合地球的实际密度分布。
A quasi-equal strength criterion for the design of discontinuous zone of pressure vessels was suggested in the sense of design by analysis. 提出一种压力容器不连续区基于分析设计的准等强度设计原则。
The results indicate: when the inner density interface extends to the Earth surface, these two quasi-equal level condition are completely equivalent. 结果表明,当参数椭球内的密度界面无限趋向表面时,两种准等位条件是完全等价的。
