Abstract
Целью данной работы является экспериментальное определение параметров давления потока жидкости, собственных частот, декрементов колебаний и ускорений отдельных отметок трубопровода, совершающего вынужденные колебания, вызванные пульсациями рабочего тела. Теоретические результаты были получены на основе конечно-элементного подхода с применением стержневой и оболочечной моделей и разных методов расчета.
The aim of this work of this develop is the experimental determination of the parameters of pressure fluid flow, natural frequencies and accelerations decrement individual marks pipeline forced vibrations caused by pulsations of the working fluid. Experiments were carried out using a vibration measuring complex designed by the authors. The theoretical results have been obtained on the basis of finite-element approach of using a core and shell models. The results obtained show the adequacy of the core and shell models when the natural frequencies and solving the problem of forced vibrations of pipelines. The resulting dynamic characteristics of the systems can be used to predict the reliability and guaranteed service life of pipelines.
