Boats and ships anti-impact protection structure principle of design is to guarantee to make fail-safe structure other structure except that inner hull absorb impact energy as much as possible by actv. plastic deformation under the little prerequisite of structure collectivity changes in weight, specifically will satisfy following requirement:
(1) body skin should be able to be delivered to impact load in the big as far as possible scope effectively reposefully, to reduce the local damage effect that thump load causes, gives full play to the energy-absorbing potentiality of body skin;
(2) medial support structures should have enough rigidity supports outer plate shells, avoid occurring descending owing to structural instability causes resistibility, and the load that can not impact owing to rigidity is excessive is delivered on the inner hull before effectively cutting down;
(3) medial support structures should design by reasonable structure form, make it in the process of transmitting the residue impact load, as far as possible equably load is shared on the inner hull,, bring into play the energy-absorbing function of Inner coverboard simultaneously to a certain extent to reduce impact earthquake intensity to inner hull.
The present invention is based on above protection principle and fail-safe structure that principle of design proposed, with conventional ship body case grillage a great difference is arranged, replace novel sandwich plate structure, and the good thin-walled semicircle pipe of sandwich employing shock resistance, so just satisfied the requirement of structure overall weight restriction; Medial support structures especially replaces the trapezoidal aggregate structure that traditional hull inner casing is extremely gone up vertical skeleton, and easier deforming absorbs energy under impact loading.
Principal feature of the present invention is embodied in:
(1) utilize the progressive Dynamic Buckling characteristic of thin-wall circular tube, outside sandwich plate is delivered to the peripheral region effectively with impact load, has increased body skin structural plasticity deformation range widely;
(2) medial support structures has remedied sandwich plate resistibility defect of insufficient for outside sandwich plate provides strong support; Simultaneously, the design of this kind version induces medial support structures that actv. energy-absorbing deformation pattern more takes place in the process of loading transfer, absorbs more energy;
(3) owing to the structure design form of trapezoidal aggregate, load is delivered on the inner hull more equably, has reduced the earthquake intensity that external load impacts, thereby has reached the purpose of the protection important cabin of boats and ships and personnel's equipment.
With respect to existing fail-safe structure, this invention has following characteristics:
(1) shock resistance is good.Because this fail-safe structure is the combined anti-impact structure based on sandwich plate and trapezoidal longitudinal aggregate, when having both advantages, has remedied deficiency separately, comprehensive shock resistance is superior;
