The specific embodiment
At first, adopt diversification thought, use orthogonal design method, set up the regression equation between wettability and alloying element.By optimal design, develop (weight %): Sn:1.70～2.50, Ni:1.80～2.50, Mn:8.50～9.50, Si:0.50～0.80, B:0.04～0.05, Zn:33～38, rare earth: 0.02～0.03, all the other are the middle inserts of Cu.
The 4 assembly sides that select wherein smelt, and have carried out the measured value of wettability and the comparison of predicted value (seeing Table 1).On the basis of prescription 4, added 0.03% rare earth element Re.Adopt differential thermal analysis to record the fusing point of 5 assembly sides to smelting the middle inserts that, its fusing point of 5 assembly sides obviously reduces (fusing point of Cu is 1084.5 ℃), reaches the requirement of this research.

Secondly, carry out the honeycomb sandwich structure design from mechanical property and damping property two aspects.
The basic design philosophy of sandwich structure is: panel is separated with fuse, to obtain bigger bending stiffness and to improve stability of structure as far as possible far.Design criteria is:
(1) sandwich must have enough shear strengths, prevents failure by shear;
(2) sandwich structure must have enough bending rigidities, produces destruction to avoid whole sandwich structure to produce excessive amount of deflection;
(3) when guaranteeing enough bending rigidities, also should consider the maximum deflection intensity that structure can be born;
(4) improve the critical buckling load that sandwich structure can bear, also promptly improved the stability of sandwich structure;
(5) honeycomb sandwich structure should have bigger vibration frequency and damping ratio under the prerequisite of same apparent size;
(6) preferably under the prerequisite of mechanical property and damping property, wish that the quality of structure is the lightest at honeycomb sandwich structure.
According to structural design criterion, from alleviating construction weight, improve six aspects of critical buckling load of shear strength, bending rigidity, bending strength, damping property and structure structure is analyzed, determine the objective function of optimization design function.Finally determine the thickness t of battenboard upper and lower panel with Multipurpose Optimal Method
f, core thickness h
c, the honeycomb lattice length of side d of regular hexagon honeycomb core and the size of honeycomb lattice wall thickness δ.According to instructions for use, table 3 between two kinds of specification cellular board sizes designing.
The cellular board size of table 3 optimization
| Numbering | Plate thickness (mm) | Core thickness (mm) | Honeycomb lattice wall (mm) | The honeycomb lattice length of side (mm) |
| 1 | 0.6 | 3 | 2.6 | 5.0 |
| 2 | 0.6 | 4.8 | 2.65 | 8.0 |
Undertaken core and substrate compound by following step then:
(1) utilize the size that designs to prepare the core of cellular sandwich damping block;
(2) prepare panel and the homemade inserts conform to design size;
(3) counter plate and core carry out surface treatment;
(4) between panel and honeycomb core, put into prescription 5 inserts, with three layers treat composite be heated in the middle of more than the melt temperature of inserts 30 ℃ (830 ℃), be incubated 2 minutes, inserts is fully melted.Enter then in the milling train, under 11% deflection, carry out compound.1# cellular board after compound has been carried out mechanical property and damping property test, and result of the test sees Table 4.
