Embodiment 1
[0033] like Figure 1-Figure 5 As shown in Fig. 1, a rubber free-form surface design method for joint products, because different joint products are used in different environments, have different performance requirements and installation conditions, therefore, firstly, according to the interface size and stiffness performance requirements of the product The effective load-bearing length L of the rubber body 2 in the product is analytically calculated through the following equations of the isotropic stiffness of the rubber nodes:
[0034]
[0035]
[0036]
[0037]
[0038] Among them: L is the length of rubber body 2, G is the shear modulus of rubber, R2 is the outer diameter of rubber body 2, R1 is the inner diameter of rubber body 2, M is the correlation coefficient of rubber hardness, and S is the bearing area ratio of inner and outer diameters ,δ 1 ,δ 2 ,δ 3 ,δ 4 Calculates the correction factor for the stiffness. In the above equations, there are only thr...
