Frame of motorcycle is the load bearing component of motorcycle most critical, and the factors such as the rigidity of vehicle frame itself, intensity, quality play decisive role to fatigue reliability, control stability, occupant's comfortableness of car load.Therefore before the vehicle frame new product puts goods on the market, must verify by Fatigue reliability testing.The Fatigue reliability testing of frame of motorcycle mainly contains actual road test, proving ground test and indoor bench test.Wherein actual road test and proving ground test, the required cycle is grown, expends large, dangerous high.Indoor bench test has very strong application prospect because having short, good reproducibility of cycle, the characteristics such as safe and reliable in the frame of motorcycle Fatigue reliability testing.The indoor bench test of frame of motorcycle at present, adopt the single-point-excitation load mode, load signal is standard simple signal or the Program Load Spectrums such as sine, step often, differ larger with motorcycle actual travel stressing conditions, are easy to occur overtesting and undertesting situation.
The utility model content
For above shortcomings in prior art, the utility model provides a kind of loading spectrum when indoor reproduction frame of motorcycle actual travel of precise and high efficiency and the tired pilot system of reproducing of frame of motorcycle actual travel loading spectrum of tired situation.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
The tired pilot system of reproducing of frame of motorcycle actual travel loading spectrum, the rear support that comprises line slideway, drives horizontal vibration exciter that line slideway loads the motorcycle fore-stock, is connected with motorcycle rear fork wheel place, to frame of motorcycle apply the vertical vibrator of simulated engine and front and back occupant's dynamic loading, at stress strain gauge, data acquisition unit, controller and the computing machine of vehicle frame key point and thin spot stickup; Described stress strain gauge connection data collector, described data acquisition unit connects controller, and controller is controlled horizontal vibration exciter and vertical vibrator, and computing machine is connected with controller.
The beneficial effects of the utility model are: this system chooses multiple spot and loads and the power control mode, loading spectrum and the tired situation when indoor reproduction frame of motorcycle actual travel of precise and high efficiency in conjunction with frame of motorcycle actual travel stressing conditions.

Fig. 1 is the tired structural representation that reproduces pilot system of frame of motorcycle actual travel loading spectrum.
In accompanying drawing: 1-horizontal vibration exciter; 2-line slideway; 3-fore-stock; 4-rear support; 5-stress strain gauge; 6-vibrator servo-valve; 7-vertical vibrator; 8-vertical vibrator; 9-stress strain gauge; 10-with the vehicle frame of engine, vibroshock and rear chain stay; 11-data acquisition unit; 12-controller; 13-computing machine.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
as shown in Figure 1, the tired pilot system of reproducing of frame of motorcycle actual travel loading spectrum, comprise line slideway 2, drive the horizontal vibration exciter 1 that line slideway loads motorcycle fore-stock 3, the rear support 4 that is connected with motorcycle rear fork wheel place, frame of motorcycle is applied the vertical vibrator of simulated engine and front and back occupant's dynamic loading (in the present embodiment, load two vertical vibrators on frame of motorcycle, be vertical vibrator 7 and vertical vibrator 8), the stress strain gauge of pasting in vehicle frame key point and thin spot is (in the present embodiment, be pasted with two stress strain gauges in vehicle frame key point and thin spot, be stress strain gauge 5 and stress strain gauge 9), data acquisition unit 11, controller 12, and computing machine 13.Stress strain gauge 5 and stress strain gauge 9 be connection data collector 11 respectively, data acquisition unit 11 connects controller 12, controller 12 is controlled horizontal vibration exciters 1 and vertical vibrator (being vertical vibrator 7 and vertical vibrator 8), and controller 12 mainly passes through the vibrator servo-valve 6 on control horizontal vibration exciter 1 and vertical vibrator.Computing machine is connected with controller.
The upper end of fore-stock 3 is connected with standpipe before frame of motorcycle, the lower end of fore-stock 3 and line slideway 2 are rotationally connected by hinged mode, horizontal vibration exciter 1 along continuous straight runs applies power to line slideway 2, and then fore-stock 3 is applied power, can simulate the front-wheel road excitation during motorcycle actual travel.Rear support 4 mainly plays a supportive role, simulation trailing wheel road excitation.The distortion and the mobile decoupling that be to adapt to vehicle frame, horizontal vibration exciter 1, vertical vibrator, rear support 4 and with all adopted rotary hinge by the test specimen vehicle frame 10 of engine, vibroshock and rear chain stay (namely with) junction.on existing frame of motorcycle actual travel loading spectrum basis, this system says the word to controller 12 by computer software, control the noise signal excitation system of horizontal vibration exciter 1 and vertical vibrator output, gather stress strain gauge 5 and stress strain gauge 9 place's response signals by data acquisition unit 11, calculate the frequency response function between each stress strain gauge point and vibrator load(ing) point, in conjunction with the frame of motorcycle actual travel loading spectrum that gathers, calculate the input signal of vibrator, by continuous simulative iteration, make stress strain gauge place response signal consistent with the frame of motorcycle actual travel loading spectrum of collection, on this basis, vehicle frame is carried out the fatigue durability test, thereby reproduce the tired situation of frame of motorcycle actual travel loading spectrum.
The tired pilot system of reproducing of this frame of motorcycle actual travel loading spectrum has following features:
1, the vehicle frame clamping is consistent with frame of motorcycle actual travel situation with loading: during the motorcycle actual travel, the load that passes to vehicle frame mainly comprises the front and back wheel road excitation, engine and front and back occupant's dynamic loading, these load are mainly horizontal direction and vertical direction.For the vehicle frame load of travelling is well reproduced, the former car engine of vehicle frame band, rear shock absorber and rear chain stay, at the flat vibrator loading simulation of front-wheel axle center water road excitation and two vertical vibrators, occupant's vertical direction dynamic loading before and after two vibrators of vertical direction are simulated respectively.
2, the mechanically decoupled solution movement interference that combines with the control decoupling zero: by line slideway and rotary hinge realization mobile decoupling to a certain extent, control thoroughly solution movement interference problem by coordination control and power to vibrator simultaneously.
3, can be at indoor accurate reproduction frame of motorcycle actual travel loading spectrum: by computer software and controller, adopt the multi parameters control method, can simulated motorcycle vehicle frame actual travel loading spectrum, in the tired situation of indoor reproduction frame of motorcycle actual travel load.
