【摘要】In order to make the frame of the rice mulching direct seeding machine meet the load-bearing requirements of the mulching direct seeding work, avoid excessive deformation of the frame and affect the flatness of the cover, and to avoid resonance between the frame and the excitation source such as the engine, ANSYS is used to perform static analysis and modal analysis on the rice mulching direct seeding machine frame. Through static analysis of three material frames and comprehensive evaluation based on the analysis results, the frame of material Q235 is the best. In the modal analysis of the Q235 rack, the first six natural frequencies of the rack are obtained. The excitation frequency of the main excitation source is compared with the first six natural frequencies of the rack, and the comparison results show that the resonance phenomenon does not occur in the work of the rack. Finally, field tests verify that the designed frame can meet the requirements of the mulching direct seeding operation.
