Study on the Current Collection Characteristics and Improvement Methods of Simple Catenary Systems

도시철도 simple catenary 가선구조에서의 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.
