Interior Noise Analysis for Rolling Stocks by Ray tracing Method

Ray Tracing 기법을 이용한 철도차량 실태소음 해석

This paper gives the way of analyzing internal noise of rolling stocks which is urgently required by civilians. Triangular beam method among ray tracing techniques is utilized to compute noise distribution of rolling stocks. Noise source and transmisstion loss of several sections from experimental work are included in this calculation. Ray tracing technique is found useful to compute big structures like rolling stocks.
