The work aims to study the frequency and vibration transmissibility at the maximum peak of the vibration transmission rate frequency curve of foamed polyethylene quickly with common design variables to reduce the workload of testing and characterization of cushioning materials.Firstly, the constant static stress experiment was designed, the results were analyzed by theoretical analysis and finite element simulation analysis, and the variables were made clear. Then the orthogonal experiment was designed, and the formula fitting was carried out by using quasi Newton method and general global optimization method. The results of constant static stress experiment showed that the peak corresponding frequency obtained by finite element simulation analysis with different weight and contact area combination remained unchanged, but the peak corresponding transmissibility would change. The R2 of the weight, the contact area between the weight and the buffer material and the thickness of the buffer material fitted with the frequency and vibration transmissibility were 0.996 and 0.951 respectively.Static stress cannot be used as a single factor affecting the change of vibration transmissibility-frequency curve. It is necessary to select the weight, the contact area between the weight and the buffer material and the thickness of the buffer material as the influencing factors of the change of vibration transmissibility-frequency curve. The frequency and vibration transmissibility corresponding to the peak value have obvious potential laws with these three factors. The fitting formula can improve the design efficiency and reduce the workload of buffer material testing.
