Abstract

In this study, the critical frequency happened at system is analyzed when the motor of camera manufacturing system is working on the direction of Z axis. Configurations of modes at natural frequencies happened at two models are investigated by the study result through modal analysis. The range of natural frequency in this study system is from 100 Hz to 500 Hz. At this range, the maximum equivalent stress in case of 20 kg weight becomes 6.2335MPa and this stress is shown as 50 times more than in case of 10 kg weight. The working safety of system can be investigated through the analyses of natural frequency and harmonic response of this camera manufacturing system.

본 연구에서는 카메라 생산 시스템의 모터가 Z축 방향으로 작업할 때 시스템에 발생하는 위험진동수를 해석하였다. 모달해석을 통하여 얻어진 결과를 보면 두 가지 모델에 발생한 고유진동들에 있어서의 각 모드의 형상을 조사할 수 있다. 본 연구 시스템에서 고유진동수 범위는 100Hz부터 500Hz로 나왔다. 모터의 무게가 20kg인 경우에 모델의 최대 등가응력이 6.2335MPa로 발생하는 것을 확인할 수 있고 이 값은 모터가 10kg인 경우의 최대 등가응력 값보다 50배 큰 것으로 나타났다. 본 카메라 생산 시스템의 고유진동과 하모닉 응답해석을 통하여 시스템의 작업 안전성을 고찰할 수 있었다.
