The different swing sources can be selected according to the specification of the swing pipe and the pressure, so as to realize the fatigue test for different types of swing pipes; moreover, the joint of the pressurizing structure can be replaced according to different mediums.
Description
Technical field
The utility model relates to the equipment that uses in the swing tube fatigue life test, a kind of swing tube fatigue experimental device.
Background technology
Swing tube is the parts that the attitude of rocket engine is adjusted, and its existing elastic property has sealing characteristics again, can produce under external force and moment loading axially, angle and combination displacement thereof, is widely used in space industry.
The torture test of swing tube is that swing tube one end is fixed on the bent plate, bent plate again with the stationary table of fatigue tester, the other end is connected with the upper grip of fatigue tester by parts such as extension bar, fixed bar and axles, the swing tube inner chamber is filled with certain test pressure, realize the existing reciprocation cycle motion that angular displacement is axially arranged again of swing tube, when mission life, stop test, check that swing tube has or not leakage.
Torture test in the past all is the axial direction displacement, does not have angular displacement, and is inconsistent with actual condition.Present development along with aerospace industry, the user proposes higher requirement to waving torture test: promptly under the test pressure of regulation, with the angle of swing tube along center of oscillation, rocking arm length and the deflection of regulation, realize the existing reciprocation cycle motion that angular displacement is axially arranged again, after the life-span of regulation, stop test, check that swing tube has or not leakage.
It is that swing tube one end is fixed that rolling test requires, and the other end links to each other with the swing source.After the pressurising of swing tube inner chamber, swing tube has certain elongation, but the link gear in swing source must have enough unlikely elongations of card swing tube of trying hard to keep, this just requires the swing source of the other end must design accurately rationally, could guarantee that the existing angle of swing tube has the reciprocation cycle motion of axial displacement again, yet from the data of consulting at present, domestic do not have this test experience to follow and do not see relevant report abroad yet.
Summary of the invention
The purpose of this utility model provides a cover swing tube fatigue experimental device, both can satisfy the spacing and pressurising requirement in the test, can realize that again axial the and angle of swing tube waves requirement.
The design's swing tube fatigue experimental device, comprise fatigue tester, rocking equipment and pressurising device, it is characterized in that rocking equipment: swing tube assembly left end is fixed on the bent plate of fixing with fatigue tester, and be connected with the pressurising device, right-hand member is connected with the extension bar level, fixed bar is vertically mounted on the extension bar, and fixed bar is connected with web joint; The supporting seat of swing tube assembly upper end is vertically fixed on the bent plate, the connecting rod that the supporting seat end is connected with web joint right angle end axle, place, web joint right angle axis hole is hung down from the testing machine crossbeam by pin, axle sleeve hinged lower portion web joint and top realizes that axial, the angle of swing tube moves repeatedly.
The swing tube fatigue experimental device is to utilize existing fatigue tester, and the novel structure of waving is overlapped in design one, selects the different sources of waving according to the swing tube specification with pressure, realizes the torture test of the swing tube of different size.The pressurising structure can be changed joint according to the difference of medium.
Description of drawings
Fig. 1 is the total synoptic diagram of swing tube fatigue experimental device;
Fig. 2 waves structural representation;
Embodiment
The swing tube fatigue experimental device be on the basis of existing testing machine 1, increase wave structure and pressurising device, waving structure sees in Fig. 1 middle frame and Fig. 2: bent plate 2 bottoms by screw retention on the worktable of fatigue tester 1, swing tube assembly 4 left ends are connected to by socket head cap screw 3 on the vertical plane of bent plate 2, and the swing tube center is facing to the pressurising hole 12 of pressurising device; Swing tube assembly 4 right-hand members are by socket head cap screw 3 and extension bar 5 horizontal fixed, and fixed bar 7 is vertically mounted on the extension bar 5 by adjusting pad 11, hexagonal nut 6, and fixed bar 7 is connected with web joint 9 by socket head cap screw 8 again; There is supporting seat 10 swing tube assembly 4 upper ends, are vertically fixed on the bent plate 2 by pin 17, socket head cap screw 3, and supporting seat 10 ends have axis hole, by axle 13 supporting seat 10 terminal axis holes are connected with web joint 9 right angle end axis hole axles; Live pin 14, axle sleeve 15 are installed, and the connecting rod 16 that testing machine 1 crossbeam is hung down is connected with web joint 9.
Web joint 9 parts are square, and short straight flange end has axis hole, is fit to axle 13, and also there is axis hole at the place, right angle, is fit to axle sleeve 15, and long straight flange end has screw, is fit to socket head cap screw 8.
During test, fatigue tester 1 drivening rod 16 pumps, pass on the swing tube assembly 4 by extension bar 5, adjust the position that testing machine 1 moves up and down, make the center line of extension bar 5 and the height that work top reaches regulation, be pressurized to test pressure for then the swing tube inner chamber, make the center line of extension bar 5 and work top reach the height of adjusting last time once more, and guarantee that the swing tube pitch of waves is even, begin official test then.In the process of the test, the swing tube deflection angle directly reads by sensor.
This device can be selected the parts such as extension bar, fixed bar, web joint, bearing of different size according to the size of the specification of swing tube and test pressure for use, thereby realizes the swing tube torture test of different size.
