In this context, diverse materials have been investigated in the search solutions for environmentally friendly.
As an alternative for reducing the environmental impact arises a new class of materials, the biopolymers.
This mixture forms a new class of materials which are bionanocomposites obtained from polymer blends with addition of chemically modified clays [4].

The main cause is that the foundation is composed of concrete structures and spring vibration isolator, which are two totally different materials.
The mesh generation of different damping materials is independent, and the boundary of material is considered as element meshing boundary, then the neighbored materials have common nodes.
Suppose there are n nodes containing the common nodes between neighbored materials, m materials of different damping, and the complex damping coefficient of material is .

But alloy material when receives the surface load, the high temperature forms the superficial oxide compound's chemical composition's change rule is with has not exerted load different [1,2].This immediate influence material operational performance.
(2) For the stretch load Cr5Mo material test specimen, it produces in the high temperature oxide compound Cr, Fe, the Mo three element content compared to do not have the load Cr5Mo material test specimen to increase obviously, showed that the load may change the alloy high temperature oxide compound truly the chemical composition.
