采用有限元法对拖拉机前支座进行静态和模态分析。得出了零件应力分布云图、变形分布云图和前五阶固有频率及振型，为零件的换材提供了可靠的理论依据。
The finite element method is used to analyze the static and modal analysis of the tractor front bearing. The part stress distribution cloud, the deformation distribution cloud and the first five natural frequencies and vibration modes are obtained, which provide a reliable theoretical basis for the part changing.
