Abstract

This paper discusses the dynamics stress of each boom, which occurs as a result of the conflicts on a multi-joint boom at the end effector and structure. In this process, CATIA was applied to create 3D modeling, ADAMS and ANSYS were then performed using mesh analysis by obtaining the stress data to create a MNF(Modal Neutral File) of multi-joint boom. Two types of MNF models were analyzed using ADAMS FFT(Fast Fourier Transform) performing to check the validity of each model. In this process, the models were verified by ADAMS, which performs the dynamic characteristics of conflict. The ADAMS Durability was used to analyze the maximum stress between the multi-joint boom and structure.

본 논문은 다관절 붐의 선단이 구조물과 충돌할 때 발생하는 각 붐의 동응력에 대해서 논하고자 한다. CATIA를 이용하여 3D 모델을 작성하고, ADAMS와 ANSYS를 이용하여 메쉬작업을 수행 후 응력데이터를 포함한 다관절 붐의 MNF를 만든다. 이 두가지 모델을 가지고 ADAMS에서 FFT해석을 수행하여 각각 모델의 타당성을 알아본다. ADAMS에서 타당성이 검증된 모델을 이용하여 붐 선단의 충돌해석에 따른 동특성 해석을 수행한다. ADAMS Durability를 이용하여 다관절 붐과 구조물의 충돌시 각 붐에 응력이 크게 발생하는 지점을 알아보고자 한다.
