Abstract
The introduction of the full paper reviews a number of relevant papers in the open literature, points out what we believe to be their shortcomings, and then proposes the design mentioned in the title, which we believe is new and better than previous ones and which is presented in sections 1 through 3. Their core consists of: "A dynamic optimized model of pipeline under constraints on dynamic strength reliability and on natural frequency was established, where the support (location, stiffness) and cross-sectional dimensions were taken as design variables and the structural weight was considered as the objective function. The support's location, stiffness, external diameter and wall thickness of a certain type of pipeline were analyzed and optimized. And the relationship between the design variables and the dynamic characteristics of the pipeline was also presented." Simulation results, presented in Figs.4 through 6 and Tables 2 and 3, and their analysis show preliminarily that the optimized design based on dynamic strength reliability of the pipeline proposed in this paper is indeed better. And the optimized pipeline has higher reliability based on the first passage principle, smaller structure weight, less dynamic stress and better vibration suppression capability.
