Principle of work:
(1) formation of simple harmonic wave vibration
As shown in figure 24: variable-frequency motor 5, by power being passed to turning axle 38, is stirred shifting fork bar 44, synchronizer 43 is engaged with the second gear 41, now, the first gear 40 dallies, and the second gear 41 does not dally, and power passes to line slideway 34 by the 3rd gear 46, the second gear 41; Locking fixture 50, is fixed on line slideway 34 connecting rod 35, and circular guideway 33 is not installed; Now, crank connecting link 30 does simple harmonic oscillation.Sinusoidal wave amplitude is by fixture 50 controlling angles, and fixture 50 can rotate around rotary screw 57, and gib screw 56 can be fixed on fixture 50 on line slideway 34.Now, crank connecting link 30 produces square wave vibration.
By rolling clamp 50, change the height of connecting rod 35, thereby change sinusoidal wave amplitude, amplitude scale has reflected the amplitude of simple harmonic oscillation accurately.
(2) formation of square wave vibration
As shown in figure 25, circular guideway 33 is not installed; Adjust the rear locking fixture 5 of fixture corner (adjusting square wave amplitude), then, in the angle of adjusting line slideway 34, make connecting rod 35 in top dead centre or lower dead center.Power is passed to gear shaft 42 by variable-frequency motor 5, now stirs shifting fork bar 44, and synchronizer 43 is engaged with the first gear 40, and the second gear 41 dallies, the first gear 40 transferring power; Power passes to line slideway 34 by partial gear 45, the first gear 40; Because partial gear 45 is incomplete teeth, its modulus is identical with the first gear 40, and its number of teeth is the half of the first gear 40, so partial gear 45 rotates a circle, the first gear 40 rotates half-turn; Now, crank connecting link 30 produces square wave vibration.
(3) generation of random wave vibration
As shown in figure 26, circular guideway 33 is installed; Locking fixture 50, variable-frequency motor 5 is passed to the 3rd gear 46 by shaft coupling by power, stirs shifting fork bar 44 synchronizer 43 is engaged with the second gear 41, and now, the second gear 41 does not dally, and the first gear 40 dallies; Power passes to line slideway 34 by the 3rd gear 46, the second gear 41; The angle control with line slideway 34 by circular guideway 33 of random wave amplitude, frequency is by the rotating speed control of variable-frequency motor 5; Complete above-mentioned steps, now, crank connecting link 30 produces random wave vibration.
As long as measure in real time the angle of line slideway 34 and circular guideway 33, just can draw the theoretical amplitude of shaking platform
(4) generation of other waveforms such as sawtooth wave
Fixture 50 is unclamped, install circular guideway 33, manually change the angle of circular guideway 33 by rocking bar 36, the change of circular guideway 33 angles can change the shape of vibrational waveform, this change is uncertain, except several specific positions can be simulated oblique wave, other position waveforms are exactly irregular; Then fix circular guideway 33D, can obtain various other waveforms, for example, when circular guideway 33 is 0 degree with horizontal line angle, obtain sawtooth wave.
The present invention adopts physical construction, and parts are few, lightweight, compact to design, and institute takes up space relatively little, is more conducive to indoor location and arranges; Testing table can complete into simple harmonic wave, square wave, random wave, sawtooth wave exciter test; Exciting displacement, frequency are all adjustable; Price is low, high precision, simple operation, testing efficiency are high, and it replaces hydraulic structure by physical construction, to improve transmission accuracy, promotes testing efficiency, reduces production costs.
