모바일 크러셔 메인프레임의 진동특성에 대한 연구

This paper studies modal impact test of main frame of a mobile crusher, which is used for rock crushing and aggregate production. For this purpose, a vibration test was performed in order to investigate vibrational characteristics of the main frame, and geometry of main frame was devised according to the sensor position of the main frame. The modal impact test results were then used as an input to the sum FRF and geometry of main frame, and level of natural frequency of main frame were investigated for analysis of the vibration mode.
