Based on the experimental study on Xingjiang-2A wheat combine driver base, the main reasons of combine vibration were analyzed. The mechanical modal of combine driver base was simplified as a rectangular plate. The differential equation and the main vibration mode function of combine driver base were set up, and the analytical expressions of combine vibration varying over time were deduced.In the structural design of driver base, the amplitude of transverse vibration and the natural frequency of this structure can meet the design requirements by changing the relevant parameters according to the relationship of each parameter.
