高速铁路轨道结构弹性衬垫材料组成的正交优化

Orthogonal optimization of Composition of a New Elastic pad Used in Track structure of High speed Railroad

本文合成了一种可用于高速铁路轨道结构的弹性衬垫新材料。这种材料由聚氨酯、芳香系加工油及其聚合物，以及玻璃粉等组成。用正交优化研究了这种材料的最佳组成和原料配比。由最优化的组成制备的这种弹性衬垫材料不仅具有比同类材料更优良的机械性能。

In this paper, a new elastic pad used in track structure of high speed railroad is synthesized. This material is composed of polyurethane, aromatic process oil and its polymer, and glass powder. Its optimum composition and proportion of raw materials are studied using orthogonal optimization. This elastic pad prepared from the optimized composition has not only better mechanical characteristics, but also lower cost than the analogous materials.
