Abstract
The utility model relates to a local-reinforced large-size fan blade comprising a blade layer spreading, wherein a blade cavity formed by the blade layer spreading is internally provided with a blade crossbeam; two ends of the blade crossbeam are respectively provided with a blade spar cap; the two blade spar caps respectively cling to the inner wall surface at one side of the blade layer spreading; the outer wall surface of the blade crossbeam is coated with a crossbeam assistant layer spreading; the outer wall surfaces at two sides of the blade layer spreading are respectively and fixedly provided with a spar cap assistant layer spreading; and each spar cap assistant layer spreading arranged at the outer wall surface of the blade layer spreading corresponds to the blade spar cap at the same side of the blade layer spreading in position. The local-reinforced large-size fan blade is not apt to damage by clamps during the process of a static test, can restore test loading conditions to the maximum limit and truly reflect the stress distribution on the whole blade.
Description
Technical field
The utility model relates to a kind of local reinforcement formula large fan blade.
Background technique
The large fan blade for testing its mechanical property, need carry out static test after production is finished.The blade that blade static test is at present adopted and the blade of actual motion adopt unified layer shop mode of structure, but in the blade process of the test, because frock clamping adopts the local folder mode of carrying that blade is pressed from both sides and carries, so often occur the situation of anchor clamps damaged blade at the trial, and therefore cause test result can not truly reflect the stressed distribution situation of blade integral.
The model utility content
The technical problems to be solved in the utility model is: easily to be damaged by anchor clamps in present large fan blade carries out static test after production is finished the process and cause the inaccurate problem of test data in order to solve, and a kind of local reinforcement formula large fan blade is provided, this blade is difficult for being damaged in by the process of anchor clamps clamping.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of local reinforcement formula large fan blade, include blade layer shop, in the blade cavity chamber that is constituted by blade layer shop, be provided with blade girder, the two ends of blade girder are provided with the blade spars cap, two blade spars caps support a side internal face that pastes blade layer shop respectively, outer wall at described blade girder has wrapped crossbeam auxiliary layer shop, and the both sides outer wall in blade layer shop all is set with spar caps auxiliary layer shop, and it is corresponding with the position that the internal face of homonymy blade layer shop pastes right blade spars cap that the blade layer is spread the set spar caps auxiliary layer shop of outer wall.This local reinforcement formula large fan blade is when doing the blade static test, blade fixture is with the spar caps auxiliary layer shop of clamping blade both sides, and not direct clamping blade layer shop, crossbeam auxiliary layer shop and spar caps auxiliary layer shop all will be assisted and bear the stress that blade is brought with the distribution blade anchor clamps, and be local impaired because of bearing too big stress to avoid blade.For guaranteeing the protection effect of spar caps auxiliary layer shop to blade, the width dimensions of spar caps auxiliary layer shop is greater than the width dimensions of blade fixture retaining part.Say that further described crossbeam auxiliary layer shop is made by the fibre cloth stack with spar caps auxiliary layer shop, the number of plies of fibre cloth stack is 3～12 layers.
The beneficial effects of the utility model are: this local reinforcement formula large fan blade is difficult for being damaged by anchor clamps in the process of carrying out static test, and reduction test loading environment to greatest extent truly reflects the stressed distribution situation of blade integral.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the sectional structure schematic representation of local reinforcement formula large fan blade of the present utility model;
Fig. 2 is for irising out the structure for amplifying schematic representation of part A among Fig. 1;
Fig. 3 is the structural representation of the local reinforcement formula large fan blade under the blade fixture clamping.
Among the figure: 1. the blade layer is spread 2. blade girders, 3. blade spars caps, 4. crossbeam auxiliary layers and is spread 5. spar caps auxiliary layers and spread 6. blade fixtures
Embodiment
A kind of local reinforcement formula large fan blade, as Fig. 1, shown in Figure 2, it includes blade layer shop 1, in by the 1 blade cavity chamber that is constituted, blade layer shop, be provided with blade girder 2, the two ends of blade girder 2 are provided with blade spars cap 3, two blade spars caps 3 support a side internal face that pastes blade layer shop 1 respectively, outer wall at blade girder 2 has wrapped crossbeam auxiliary layer shop 4, and the both sides outer wall in blade layer shop 1 all is set with spar caps auxiliary layer shop 5, and it is corresponding with the position that the internal face of homonymy blade layer shop 1 pastes right blade spars cap 3 that the blade layer is spread the set spar caps auxiliary layer shop 5 of 1 outer wall.This local reinforcement formula large fan blade is when doing the blade static test, blade fixture 6 is with the spar caps auxiliary layer shop 5 of clamping blade both sides, and not direct clamping blade layer shop 1, crossbeam auxiliary layer shop 4 and spar caps auxiliary layer shop 5 all will be assisted and bear the stress that brings with 6 pairs of blades of distribution blade anchor clamps, and be local impaired because of bearing too big stress to avoid blade.For guaranteeing the protection effect of the 5 pairs of blades in spar caps auxiliary layer shop, the width dimensions of spar caps auxiliary layer shop 5 is greater than the width dimensions (referring to Fig. 3) of blade fixture 6 retaining parts.
Make by the fibre cloth stack with spar caps auxiliary layer shop 5 crossbeam auxiliary layer shop 4, and the number of plies of fibre cloth stack is 3～12 layers.
