求翻译：因此，应该选用金属弹性材料，而且所选弹性材料许用切应力必须大于τ ’max才能保证弹性元件材料不会断裂。表1为常用弹性元件材料的基本参数。是什么意思？

Therefore, you should use a metal elastic material the selected elastic material and the allowable shear stress must be greater than τ 'max in order to ensure the elastic element material does not break. Table 1, the basic parameters for common resilient element material.

Therefore, it should be optional metal elastic material, and the elastic material in all stress must be greater than to be ' Max elastomeric material can be guaranteed without breaking. Table 1 is the common elastomeric material's basic parameters.

Therefore, should select the metal elastic material, moreover chooses the elastic material to permit with the shear stress must be bigger than tau' max to be able to guarantee the elastic part material cannot break.Table 1 is the commonly used elastic part material basic parameter.

Therefore, you should use metal elastic material, and shortly after selected elastic material with shear stress must be greater than τ ' max elastic element material will not fracture can be assured. Table 1 basic parameters of elastic components for commonly used material.
