Further, described two matrix cavity body comprise inverted ladder type or " V " type or " U " type that is out suitable for reading; Weld elongated reinforced rib more than between the oblique lower plate bottom surface of two matrix cavity body and between main cavity body lower plate bottom surface;
Described floor group is by polylith floor horizontal vertical or crisscross be equidistantly or unequal-interval is formed;
The installation site of an above upper strata shock resistant vibration isolation device of installing on the upper plate of described main cavity body and matrix cavity body and the corresponding installation of under-chassis of basic propulsion system; The installation site with levels shock resistant vibration isolation device that install the lower plate bottom surface of main cavity body and matrix cavity body cooperates installation with the hull pedestal; Described upper strata shock resistant vibration isolation device and lower floor's shock resistant vibration isolation device are that rubber impact hits vibration isolator or steel rope shock resistant vibration isolation device;
The upper plate of described main cavity body and two matrix cavity body and the spacing between the lower plate are more than the 5cm; Spacing between the described two matrix cavity body horizontal center lines is more than the 150cm;
Floor bilateral clearance in the upper surface of described two matrix cavity body bottom level cavity body and the horizontal cavity body is provided with the three-dimensional limiting device.
Cavity body that constitutes by upper plate, lower plate, floor group and the boats and ships basic propulsion system modularized shock resistant buoyant raft of forming jointly with the shock resistant vibration isolation device, its principle of work is:
Vibration isolation principle: many basic propulsion systems form scratches moving source and multimass body more, reaches the reduction level of vibration by mass action principle each other, and the damping force characteristics by the shock resistant vibration isolation device absorbs vibrational energy, finally reaches the vibration isolation effect;
Shock resistance principle: by the optimum damping ratio of multimass body, store, delay and put impact energy, reach and reduce the suffered impulsive force of basic propulsion system to energy absorbing and selection shock resistant vibration isolation device etc.
Adopt above technical scheme, the beneficial effect that the utility model reaches is:
The alternation disturbance force that a, this buoyant raft produce basic propulsion system plays the effect that absorbs and stabilize, effectively absorb the basic propulsion system vibrational energy, and the separating vibration energy is to the hull transmission, reduced vibrational energy, further dissipate by the energy of vibration isolator, thereby reduced the harm of vibration boats and ships to vibration;
B, this buoyant raft can reduce the impulsive force that basic propulsion system is produced, and reduce the injury to basic propulsion system, improve disguise, usability and the survivability of naval vessels.
C, this buoyant raft make basic propulsion system and shell Elastic Contact, and the vibration of avoiding producing is directly delivered to each cabin of boats and ships, can improve the quietness of boats and ships, thereby improve the working environment of underwater acoustic system and other precision equipment and occupant's living environment.
