Abstract: For the post embedded parts of honeycomb sandwich structures with complex structures, a lot of time is usually consumed in the finite element calculation. In the simulation analysis of the tensile bearing capacity of the post embedded parts of honeycomb sandwich structure, the mass scaling method is used to improve the calculation efficiency of the model, and the accuracy and time of simulation calculation are compared. First of all, in ABAQUS, the simulation analysis of honeycomb sandwich structure post embedded parts without mass scaling technology is carried out and compared with the test results to verify its accuracy. Then, after the mass of the model is expanded by 10², 10⁴ and 10⁶ times respectively by using the mass scaling method, the simulation analysis of the rear embedded parts of the honeycomb sandwich structure is carried out and compared with the model results without using the mass scaling technology. The simulation accuracy is verified by comparing the pull off failure load displacement curve and the specimen failure form, and the calculation time is compared. The results show that when using mass scaling technology to analyze the tensile bearing capacity of the post embedded parts of honeycomb sandwich structures, the calculation accuracy can be guaranteed, and the calculation time can be greatly saved, which provides an efficient calculation method for the study of the tensile bearing capacity of the post embedded parts of honeycomb sandwich structures.
