Description
Technical field
The present invention relates to the suit structure of national defense construction and aerospace field, espespecially a kind of fastening structure of suit face-port and fastening method thereof.
Background technology
Along with the iterative method of aerospace industry, astronaut's extravehicular work will be further frequent.And the face-port on the suit helmet is as the key component on suit, except must possessing good optical property, the security performance such as resistance to pressure, air-tightness depends primarily on being fastenedly connected of face-port and suit.
For meeting the requirement of astronaut when extravehicular work to environment perception, suit face-port Most optical is functional and possess the Transparent Parts such as the glass of some strength, but it belongs to fragility material, has the shortcomings such as impact strength is low, hot strength is low, compressive strength is low, bearing strength is low, resistance to stress poor performance, the coefficient of expansion are high, extension is strong, elastic modelling quantity is little, flexural strength is low, yield strength is low.
As shown in Figure 1, when a plane object is placed in rigid border, when applying evenly load in the plane, can depressed deformation be there is in this object plane, its inside can creating antagonism property stress, and edge is subject to rigidity restraining factors formation stress concentration effect, when antagonism stress exceedes the performance boundary of this object edge material, this object edge can damage.
Air pressure in space is almost nil, and the basic living necessities for meeting spacefarer in suit must keep about standard atmospheric pressure, there is larger pressure differential inside and outside suit.Current suit face-port generally adopts to be inlayed perforate to the preformed groove of the suit helmet or on face-port and is secured by bolts in the mode on the suit helmet, described mode is all be held in rigid border by the face-port of fragility, when face-port side is subject to even air pressure, Force principle when being simultaneously subject to evenly load according to the shortcoming of above-mentioned face-port, face-port and the environment for use of suit, the edge strength of this fragile material just seems particularly important, once process bad being easy to occur the safety problems such as crack.For the pressure differential that reply suit exists in space, ensure the Strength and stability of its structure, face-port edge needs corresponding increase to the thickness of suit helmet junction; Owing to being subject to optical requirement and restriction simultaneously, the integral thickness of face-port must be consistent, and locally cannot increase thickness because the bursting stress at face-port edge is comparatively large, therefore during design have to the integral thickness of face-port to strengthen, can cause certain influence to the optical property of face-port so undoubtedly, its internal stress change is simultaneously also more complicated.In addition also there is following defect in the connected mode of above-mentioned suit face-port and the helmet:
1, in the manufacturing and process, more or less can there is certain defect or residual stress in suit face-port, comprise the operations such as grinding, polishing and annealing and all can damage the interior stress balance of face-port self; The follow-up process transporting, storing in a warehouse or assembling all may cause this defect or stress to amplify gradually, there is larger potential safety hazard in the future.
2, circular arc requires higher to the processing technology of face-port, the processing dimension of face-port or radian etc. certainly exist certain error, there is flatness error in the contact surface of the same suit helmet and face-port junction, or do not aim at completely with the center of the respective aperture on the helmet at the center of face-port edge screw, or there is crackle at the bolt hole of face-port edge, breach, the defects such as polishing is bad, above-mentioned situation all can affect the laminating degree of face-port and the suit helmet, thus cause face-port that difficulty is installed, or there is stress after installing to concentrate, and the interchangeability of face-port goods is poor.
3, when suit face-port is mounted on the suit helmet by the mode of inlaying, its structure fail to make suit face-port and suit helmet-shaped integral, but when suit face-port deforms because of the reason such as the temperature difference, pressure reduction, the bonding force of resin filling layer to cause between the helmet to resist face-port mastication forces because of distortion is only relied between face-port and the helmet, when the bonding force of resin filling layer cannot resist the mastication forces brought because of face-port distortion, face-port is just easy to come off from the suit helmet, thus causes serious security incident.
4, when the mode that suit face-port is fastened by bolts is mounted on the suit helmet, though its structure can make suit face-port and suit helmet-shaped integral, but on face-port, offer the interior stress balance that installing hole has just destroyed face-port self, the weak link in intensity is become near screw, add the manufacturing deficiency and erection stress that may superpose, face-port is easy to crack, this will be very serious potential safety hazard.
5, when astronaut is in extravehicular work, the air pressure in space is zero substantially, and must remain about atmospheric pressure in suit; In space, astronaut's operation's circumstance of temperature difference can reach about 300 degree, and must substantially maintain about 20 DEG C in suit.Suit face-port is under pressure reduction so and temperature difference condition, and any slight residual stress near above-mentioned screw or erection stress, be all extended easily to crackle, even crack and the security incident such as cause that face-port breaks.
6, because face-port is different from the thermal coefficient of expansion of the helmet, in face-port, the thermal coefficient of expansion of each layer transparent body is different, its deformation extent is also different, and also there is very big-difference in temperature variant rule, so when pressure reduction and the temperature difference change, except the helmet that rigidity is larger can limit the transversely deforming of face-port, cause outside the lateral stress of face-port and helmet junction increases, the stress state of other complexity is also there will be near both contact surfaces, time has been grown and has produced fatigue crack with regard to easy at screw iso-stress weakness, until face-port destroys cause catastrophic consequence.
7, because bolt can conduct heat, if under suit face-port is exposed to high temperature for a long time, temperature passes to bolt hole surface by bolt and effective bearing area in hole is diminished, and the wearing and tearing of face-port upper bolt hole and distortion in suit use procedure is in addition all very unfavorable to the Strength and stability of total.
The mounting structure of suit face-port is roughly the same in the world at present, just the material of face-port and manufacturing process improve to some extent, the fastening structure of face-port and the suit helmet there is no radical change, the problems referred to above still exist, and suit face-port fastening structure also becomes a great problem of puzzlement person skilled.
But along with the progress in epoch, the development of space industry is more and more taken seriously, and the demand of people to suit is also growing on and on, but the core technology that effectively can promote the security of suit face-port and convenience is still unresolved.There is no more rational settling mode at present for problems, and the present invention fills up the blank in this field.
