Abstract

In this study, we analyze the static and dynamic characteristics of a bulk-cement trailer with a simpler structure that carries powders. The commercial software ANSYS is used to prepare a detailed three-dimensional model of the chassis frame and tank body that bear most of the load of a bulk-cement trailer for the finite element analysis. Modal analysis is conducted to examine the dynamic characteristics of the trailer body, and static analysis shows weak links in the structure. Finally, we propose a method to increase the strength of vulnerable areas and to reduce the weight of the trailer by applying the Taguchi method.

본 논문에서는 하부 프레임 구조가 보다 단순해진 분말류 운송차량인 벌크시멘트 트레일러의 정동적 특성을 유한요소해석을 통하여 분석하였다. 이를 위하여 벌크시멘트 트레일러가 받는 하중의 대부분을 지지하는 섀시 프레임과 탱크부분을 상용 유한요소해석 소프트웨어인 ANSYS를 이용하여 삼차원 상세 유한요소모델링을 수행하였다. 자유진동해석을 통하여 차체의 동적특성을 이해하는데 필수적인 벌크시멘트 트레일러 몸통의 고유진동수와 진동모드를 분석하였다. 또한, 정적인 응력해석을 통하여 트레일러의 취약부위를 찾은 후 다구찌 실험계획법을 적용하여 경량화를 시키면서도 취약부위의 강도를 높일 수 있는 방안을 제시하였다.
