Abstract.
The design constraints include three aspects: (1) the stiffness of vibration isolation system is enough such that the resonant peak frequency is separated from control system and flexible part, such as solar array; (2) the system has certain attenuation for high-frequency range that induced by momentum wheel; (3) the damping is not much large so the damping material is easily obtained.

For example, under the earthquake effect the prism of the steel reinforced concrete frame structure produce plane torsion deflection, and also bears the load coming from the vertical load which applied on the beam .under this circumstances, the prism of SRC structures is in the composite state of pressure and torsion, and the most failure of the component caused by pressure and twist combination
Material model and Unit type
Steel and rebar’ constitutive relationship reduced to the ideal elastic-plastic constitutive stress-strain relationship, according to the need of this paper.

The ZTR refers to the numerical distribution for high in middle and low in south and north in the Sa II + III reservoir group in the research area, obviously the northwest and southwest trend to range from small to large, along the direction that clastic composition maturity is high and transportation distance is far, indicate that there are two provenances in the research area, mainly the provenances of northwest and southwest, and provenance provided material basis for the formation of the sedimentary system, thus it can indirectly indicate the control scope of the sedimentary system, and through the characteristics of heavy mineral assemblage in the research area, two sedimentary systems agree with each other.
