저진동 차체 설계를 위한 조인트 해석 기법에 관한 연구

We investigate various modeling techniques for static and the low-frequency dynamic analyses of thin-walled joint structures. First, we discuss typical modeling techniques using conventional beam elements with six degrees of freedom. Secondly, we address the importance of practical higher-order beam elements including distortion and warping for realistic analysis of joint structures. Finally we present thin-walled joint modeling techniques using higher-order thin-walled beam elements. Comparing numerical results obtained from various modeling methods, we show the critical role of higher-order beam elements in obtaining meaningful results.
