모드중첩법을 기초로 한 집전성능해석 프로그램 개발

초록

A dynamic simulation program for pantograph-catenary system is developed based on a mode superposition method to predict current collection performance. Formulations for the dynamic simulation are presented in this paper. The number of modes which should be considered for a KTX catenary system is reviewed through frequency response analyses. The responses for GPU pantograph-KTX catenary system are simulated with various train speeds. The our simulation results are in reasonably good agreements with RTRI simulation program. SNCF simulation program, and BR simulation program.
