도시철도 simple catenary가선구조에서의 집전성능 향상방안에 관한 연구

The decisive criteria to determine collection performance is the contact force between pantograph and catenary. The contact force consists of a static force and dynamic force related to vibration characteristics, train speed and etc. The low contact force leads to the loss of contact, and most countries regulate it below 3~5% at operation speed. This study presents a technical overview of criteria for collection performance and modelling and simulation methods to analyze dynamic characteristics of catenary.
