| Abstract:To verify the rationality of fuel oil gear box improvement design, finite element calculation analysis was carried out on the gear box after thinning improvement, and the deformation of key parts, stress data were obtained. The data analysis results show that the structure stress of the gear box is not beyond the material's allowable stress, thus meets with the requirements. The research lays a good foundation for the structural optimization of the gear box in the future. |
