This paper takes the scissor type seat of a domestic combine harvester as the research object, uses CATIA software to carry out three-dimensional modeling of the seat, and then imports the seat model into ANSYS Workbench software for static analysis and modal analysis, so as to judge whether the scissor type seat of the combine harvester meets the design requirements. The results of static analysis show that the maximum stress of the seat under the two different loads is less than the yield strength of the material, and the overall strength of the seat meets the design requirements. The modal analysis results show that the first six natural frequencies of the seat completely avoid the sensitive frequencies of the human body, which basically guarantees the working comfort of the driver. This study provides a theoretical basis for the structural design and optimization of combine seat.
