Modal Analysis of Seat Frame of Bulldozer's Cab Based on Finite Element Method

Abstract:

As the seat frame is an essential structure of bulldozer's cab, dynamic characteristics of the structure are particularly important. The finite element model of the seat frame was established by CATIA software, and then modal analysis was carried out in absolute freeness. After investigating inherent frequency and vibration mode of several typical modes seriously, dynamic characteristics of the frame were clear. Weak links of the structure were obtained on the basis of analysis result, and structure improvement was conducted. Finally, the comparison and analysis was carried out between the unmodified seat frame and the modified one, the result shows that the dynamic characteristic of seat frame is optimized.
