【Abstract】 The structure of the bed used for doors and windows on all sides was designed, and the finite element method was used for static analysis and modal analysis. According to the analysis results, the unreasonable structure was optimized and improved, which could provide guidance for the structural design of special foursided planer for door and window. The whole structure of the four-sided planer was designed, and the installation position of key components on the bed were determined, which provided a reference for the analysis of the bed during the static analysis. Based on ANSYS, the static analysis and modal analysis of the bed were improved. It was concluded that a static analysis of the bed structure was carried out to obtain the corresponding stress cloud diagram, strain cloud diagram, and deformation cloud diagram. The results showed that the bed rigidity and strength of the four-sided planer could meet the design and operating requirements. Based on the modal analysis structure, the structure of the bed was optimized, so that the natural frequency satisfied the processing requirements, which could prevent resonance from occurring, improve the stability of the entire machine operation, and ensured the processing quality of the door and window materials.更多还原
