Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1 to Figure 2, a kind of embodiment according to the specific embodiment of the invention is: a kind ofly analyze the simulation experiment platform of out-of-balance force on the impact of crackle axle, it comprises base 1, chuck 2, slide group and out-of-balance force simulation mechanism, wherein: base 1 be each side provided with a bracing frame 11, these two bracing frames 11 are oppositely arranged.Two chucks 2 are respectively rotatably arranged on a bracing frame 11, and on the same line, two chucks 2 are respectively used to the two ends clamping crackle axle 7 to the center line of these two chucks 2, for the fixing crackle axle 7 of installation.Rotating mechanism rotates for driving one of them chuck 2, thus drives crackle axle 7 to rotate.Preferably, as shown in Figure 1, rotating mechanism is a rotary electric machine 21 being arranged on base 1, and rotary electric machine 21 is connected with the chuck 2 being positioned at left side, thus drives the chuck 2 in left side to rotate.Further preferably, the bracing frame 11 being positioned at right side is arranged on base 1 in the mode that can horizontally slip, thus can adjust the distance between two bracing frames 11, to be applicable to install the crackle axle 7 of different length and fix.
Base 1 is at least provided with a slide group, the slide 3 that each slide group is arranged before and after comprising two, and slide 3 is arranged on base 1 in the mode that can horizontally slip, each slide 3 is provided with an out-of-balance force simulation mechanism 4, thus in slide group two out-of-balance force simulation mechanisms 4 are oppositely arranged.As shown in Figure 2, out-of-balance force simulation mechanism 4 comprises cam 41, cushion block 42, curved splint 43 and spring 44, and cam 41 is rotatably set up on slide 3, and cam 41 is rotated by an actuating unit driving.Preferably, actuating unit is one to be arranged on slide 3 and to carry out with cam 41 cam motor 45 that is connected.Cushion block 42 is can the mode of slide anteroposterior be set up on slide 3, cushion block 42 contacts with cam 41, curved splint 43 is connected by spring 44 with cushion block 42, curved splint 43 is for being clamped in the position of crackle axle 7 containing crackle, curved splint 43 can the mode of slide anteroposterior be arranged on slide 3, also can by strut can the mode of slide anteroposterior be arranged on base 1.
When crackle axle 7 is installed on after on two chucks 2, two out-of-balance force simulation mechanism 4 symmetries in slide group are positioned at the both sides, front and back of crackle axle 7, two curved splints 43 of these two out-of-balance force simulation mechanisms 4 are folded in the position containing crackle on crackle axle 7 symmetrically under the effect of spring 44, when the position that cam 41 contacts with cushion block 42 transfers lug boss to gradually by non-lug boss, cushion block 42 can be promoted move to crackle axle 7, thus make spring 44 compress further gradually, the acting force of continuous increase curved splint 43 pairs of crackle axles 7, on the contrary, when the position that cam 41 contacts with cushion block 42 transfers non-lug boss to gradually by lug boss, the acting force of curved splint 43 pairs of crackle axles 7 just can reduce gradually.Therefore carrying out at cam 41 can by curved splint 43 dummy activity out-of-balance force containing cracks on crackle axle 7 in the process of rotating.Structure of the present invention is simple, stable action, simulate true to nature, when installing foil gauge at the detection position of crackle axle 7, foil gauge just can export dynamic strain measuring instrument to the STRESS VARIATION detecting position generation in the process of simulation, dynamic strain measuring instrument is transported to computer data again, just can carry out collection and the analysis of related data, thus conveniently on the impact of the Crack Extension of crackle axle, simulated experiment be carried out to analysis out-of-balance force.Because slide 3 can horizontally slip, out-of-balance force simulation mechanism 4 therefore can be made can to adjust to arbitrary simulation needing the position detected to carry out out-of-balance force effect on crackle axle 7.
