Abstract

Air-core reactors have become the main source of electromagnetic contamination in substations. In this project, the scaling methods for small-scale experimental technique will be studied, in order to provide validation of the analytical and numerical calculation, and to help to predict the MF around air-core reactors. Firstly, the scaling rules of the parameters for air-core reactors are summarized firstly. Then a full size, 1/2 size 1/6 size of air-core reactors are put forward in order to study the MF of the origin size by analytical calculation, numerical simulation and small-scale experiment. All the results verify the effectiveness of the scaling rules and the equivalency of small-scale experiments.

Abstract

the reliability and vibration performance test of vibratory rollers have been done in the test field to ensure that the vibratory roller meet the quality requirement. At present, the indoor test stand for vibratory roller has not yet been studied at home and abroad. This paper designs the indoor test stand for vibratory roller and makes simulation analysis by the numerical model of vibration-drum and test stand. The vibration isolation system of test stand is determined as a function of the test stand mass (m2), the stiffness of rubber tire (k1) and the stiffness of the vibration isolation block (k2). The test results showed that the vibration drum-test stand model can account for the vibration isolation system.
