给出了单圆轮载和双圆轮载作用下不同层间接触条件 (光滑、连续 )的双层结构顶面当量模量回归显式 ,多层结构的近似换算式。这些公式具有物理意义明确 ,外延性好 ,精度较高等优点
The approximate formulas of the top equivalent moduli of two-story structures with different contact conditions (smooth and continuous) under single-wheel and double-circle wheel loads are given. These formulas have the advantages of definite physical meaning, good extensibility and high precision
