Abstract：In order to study the mechanical behavior of latex foam under compression in two-dimensional plane, the microstructure of bedding latex foam was analyzed by scanning electron microscope. The porosity of latex foam in bedding was calculated by Photoshop and ImageJ software. In the finite element ABAQUS software, two-dimensional planar method was used to create latex parts with tiny circular holes and holes in the components, and the he gap ratio is 72%, setting up the simulation experiment steps, obtaining the two-dimensional simulation results of compression, comparing it with the uniaxial compression experimental results and three-dimensional simulation Two-dimensional simulation study on compression performance of latex foam for beddingresults, we can see that the fitting degree of two-dimensional simulation is more than 95%, which is higher than that of Ogden 2 order parameter simulation method and super elastic foam uniaxial compression test data simulation method. Therefore, two-dimensional simulation is effective and feasible for simulating the compression performance of latex foam. The two-dimensional simulation method provides a convenient method for subsequent latex bedding development and saves research time.
