Two Dimensional Vibration Analysis of Cranck Shaft by Using Transfer Matrix Method
전달매트릭스법을 이용한 크랭크축의 2차원 진동해석
Abstract
This paper present an analysis method of crankshaft of four cylinder internal combustion engine for studying dynamic characteristics of the shaft. For simple analysis, uniform sections of journal, pin and arm parts were assumed. Transfer Matrix Method was used, considering branched part and coordinate transformation part. Natural frequencies, natural modes and transfer functions of crank shaft were investigated based upon the Timosenko beam theory: It was shown that the calculated natural frequencies, modeshapes agree well with the experimental results.
