Abstract
In this paper, inversion schemes for reconstruction of load and constraint of pipeline structure of a liquid rocket engine for global vibration evaluation of pipelines has been proposed and validated. The method involves modeling for forward simulation of random vibration and a multistep inversion scheme to reconstruct the unknown load and constraint parameters. In parallel, a piping structure vibration experimental system was also established to acquire the measured vibration signals for experimental validation of the numerical method. From both the numerical and experimental results, it was verified that a fine finite element model of a pipeline structure can be established based on the reconstructed load and constraint parameters which enables a global vibration evaluation of the pipeline structure based on limited vibration information.
期刊介绍:
The aim of the International Journal of Applied Electromagnetics and Mechanics is to contribute to intersciences coupling applied electromagnetics, mechanics and materials. The journal also intends to stimulate the further development of current technology in industry. The main subjects covered by the journal are:
Physics and mechanics of electromagnetic materials and devices
Computational electromagnetics in materials and devices
Applications of electromagnetic fields and materials
The three interrelated key subjects – electromagnetics, mechanics and materials - include the following aspects: electromagnetic NDE, electromagnetic machines and devices, electromagnetic materials and structures, electromagnetic fluids, magnetoelastic effects and magnetosolid mechanics, magnetic levitations, electromagnetic propulsion, bioelectromagnetics, and inverse problems in electromagnetics.
The editorial policy is to combine information and experience from both the latest high technology fields and as well as the well-established technologies within applied electromagnetics.
