In certain preferred embodiment:
The quality of effectiveness in vibration suppression is evaluated by level (need point out evaluation criteria) of shaking with intrinsic frequency f, vibration acceleration a or Z usually.Intrinsic frequency f is by formula
C=Dynamic Spring rigidity
The weight of m=superstructure+
The nonspring carried mass of wheel
Calculate, as can be seen from formula, when quality is certain, the rigidity of damping material is less, and intrinsic frequency is less, and effectiveness in vibration suppression is better; When rigidity is certain, quality is larger, therefore has frequency less, and effectiveness in vibration suppression is better.Certainly, also to consider that the settling amount of damping material meets the demands simultaneously.
The selection of material: about the select permeability of building foundation vibrating isolation system damping material used, because of building structure and highly different, needs to carry out calculatings selection according to detailed parameter.The selection of material needs to follow two basic points:
1, because of the difference of constructure inner structure, in the same plane showing building foundation, the pressure load of diverse location is different, so, when carrying out vibration damping holder Material selec-tion and calculating, first it is identical for needing to ensure to install the settling amount on body basis, building after vibration damping holder, namely by selecting different damping materials to be arranged on corresponding building foundation position, the compressive strain reaching damping material is identical, ensures the safety of building;
2, the effectiveness in vibration suppression in order to meet design requirement, we can consider, in sufficient surplus situation, to carry out the design of vibration damping scheme, and determine the kind of damping material according to structure parameter and vibration data.The static load scope of damping material that we adopt from 1.1 tons/square meter to 600 tons/square meter not etc., fully can meet the load needs of building structure.
