Description
Technical field
The utility model relates to a kind of hydraulic pressure resistant, corrosion-resistant, light composite cylindrical thin-walled casing that is applied in fields such as deep-sea oil exploration, optical cable laying, hydraulic system, chemical industry, particularly relates to a kind of light composite cylindrical thin-walled casing that fiber reinforced thermosetting resin constitutes that covers outside on the hard aluminium alloy cylinder.The utility model is the improvement to the hydraulic pressure resistant cylindrical thin-walled casing of existing use metal material or the manufacturing of fiber reinforcement engineering plastics.
Background technology
The sensor that uses under high hydraulic pressure or the thin-wall case of detector must anti-high hydraulic pressure, corrosion-resistant.In addition, these housings also must light weight, so that enough buoyancy to be provided, make housing within it portion carry sensing element as much as possible or exploring block.
When adopting stainless steel, titanium alloy or rustproof aluminum alloy as the material of the withstand voltage thin-wall case of this class, housing has the good advantage of hydraulic pressure resistant performance, but their quality greatly, not corrosion-resistant.Because stainless steel proportion is 7.8g/cm
3So, be not suitable for doing the withstand voltage thin-wall case of small size of sensor or detector.Titanium alloy cost and difficulty of processing are all very high, and density is 4.8g/cm simultaneously
3, also be not suitable for doing the withstand voltage thin-wall case of small size of sensor or detector.What at present domestic this class thin-wall case material employing was more is rustproof aluminum alloy, but aluminium is a kind of active metal, can not bear corrosive liquids and soak for a long time, and the proportion of alloy aluminum is also greater than 2.7g/cm simultaneously
3
The hydraulic pressure resistant performance of rustproof aluminum alloy during as withstand voltage thin-wall case material promptly causes the hydrostatic of housing flexing unstability, is called critical pressure Pcr.If require detector to carry the hydrostatic of 6MPa, the elastic modulus E=70GPa of rustproof aluminum alloy with cylindrical shell; Shear modulus G=26.5GPa; Poisson's ratio γ=0.3,
The critical pressure Pcr of time sealing cylindrical shell can be calculated by following formula:
Here, D is the internal diameter of cylindrical shell; T is the wall thickness of cylindrical shell; 1 is the length of cylindrical shell.When wall thickness t=2mm, the critical pressure Pcr=2.1MPa of cylindrical shell; When wall thickness t=2.5mm, critical pressure Pcr=3.5MPa; When wall thickness t=3mm, critical pressure Pcr=5.5MPa; When wall thickness t=3.5mm, critical pressure Pcr=10.5MPa.Generally speaking, the safety coefficient of composite gets 1.5.When cylindrical shell design wall thickness 3.5mm, the sealing cylindrical thin-walled casing that rustproof aluminum alloy is made is stable, no flexing unstability.
Fiber-resin composite has light weight, corrosion resistant characteristic, but hydraulic pressure resistant not.The solution of a kind of alternative rustproof aluminum alloy of carbon fiber-reinforced thermosetting resin Ceng Zuowei.Carbon fiber-reinforced thermosetting resin light weight, corrosion resistance is strong and have very high hot strength and stretch modulus, but the modulus of shearing of carbon fiber-reinforced thermosetting resin is low, and can the flexing unstability under high hydraulic pressure.
The flexing unstability can be by ANSYS finite element analysis prediction.At first, establishing carbon fiber, to strengthen the mechanical performance of the poly-unidirectional laminate of BMI as shown in table 1:
Table 1a carbon fiber strengthens the mechanical performance of the poly-unidirectional laminate of BMI
| Hot strength [MPa] | Stretch modulus [GPa] | Compressive strength [MPa] | Modulus of compressibility [GPa] | Shear strength [MPa] in length and breadth | Modulus of shearing [GPa] in length and breadth |
| 2630 | 172 | 1480 | 169 | 109 | 3.9 |

| 62 | 7.0 | 213 | 8.1 | 0.33 | 1.52 |
See also shown in Figure 1ly, utilization ANSYS finite element analysis program obtains the finite element analysis model that carbon fiber strengthens poly-BMI rounding cylindricality thin-wall case.This model is that one one end sealing, wall thickness are the cylinder of 3.5mm.In ANSYS finite element analysis program, select Nonlinear Composite cell S hell91 for use, listed performance parameter in the input table 1 loads analysis.The direction of getting carbon fiber becomes with the cylinder axis direction+45 degree or-miter angle.Carbon fiber twines 7 layers altogether on each direction; Every two-layer, change the carbon fiber winding direction one time.
Then, choose the load option of ANSYS finite element analysis program, the beginning finite element solving.At the outer surface of cylindrical model and the outer surface of model encapsulates end, load initial well-distributed pressure 1MPa.For the barrel that makes cylindrical model is surrendered, on the plane of symmetry of cylindrical model outer surface length direction, look for a node again when reaching critical load.On this node, the pressure that radially applies a 200N extracts the change in displacement value that this node produces diametrically as perturbed force, and extracts the counter-force of a certain node of cylindrical model openend.
See also shown in Figure 2ly, can obtain the relation of radial displacement and load like this.Be the X reference axis, be the Y reference axis with the counter-force that is extracted with the radial displacement that is extracted.Because counter-force X and radial displacement Y are negative values, so the direction that counter-force and radial displacement numerical value increase is opposite with the direction of reference axis.Fig. 2 demonstration, when load factor is increased to 5.4MPa gradually, the radial displacement flip-flop of node, whole cylindrical shell flexing unstability.The cylindrical shell that carbon fiber strengthens poly-BMI manufacturing can not bear 6MPa hydraulic pressure.
