Principle of work:
(1) formation of simple harmonic wave vibration
As shown in figure 24: variable-frequency motor 5, by power is passed to turning axle 38, stirs shifting fork bar 44, synchronizer 43 is engaged with the second gear 41, now, first gear 40 dallies, and the second gear 41 does not dally, and power passes to line slideway 34 by the 3rd gear 46, second gear 41; Locking fixture 50, makes connecting rod 35 be fixed on line slideway 34, and does not install circular guideway 33; Now, crank connecting link 30 does simple harmonic oscillation.Sinusoidal wave amplitude is by fixture 50 controlling angle, and fixture 50 can rotate around rotary screw 57, and fixture 50 can be fixed on line slideway 34 by gib screw 56.Now, crank connecting link 30 produces square wave vibration.
By rolling clamp 50, change the height of connecting rod 35, thus change sinusoidal wave amplitude, amplitude scale reflects 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 fixture corner (namely adjusting square wave amplitude) locking fixture 5 afterwards, then in the angle of adjustment line slideway 34, make connecting rod 35 be 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, and the first gear 40 transmits power; Power passes to line slideway 34 by partial gear 45, 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, power is passed to the 3rd gear 46 by shaft coupling by variable-frequency motor 5, and stir shifting fork bar 44 and synchronizer 43 is engaged with the second gear 41, 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, second gear 41; Random wave amplitude is controlled by the angle of circular guideway 33 with line slideway 34, and frequency is controlled by the rotating speed of variable-frequency motor 5; Complete above-mentioned steps, now, crank connecting link 30 produces random wave vibration.
As long as measure line slideway 34 and the angle of circular guideway 33 in real time, the theoretical amplitude of shaking platform just can be drawn
(4) generation of other waveforms such as sawtooth wave
Fixture 50 is unclamped, install circular guideway 33, the angle of circular guideway 33 is manually changed by rocking bar 36, the change of circular guideway 33 angle can change the shape of vibrational waveform, this change is uncertain, except several specific position can simulate oblique wave, other position waveforms are exactly irregular; Then fix circular guideway 33D, other waveforms various can be obtained, such as, when circular guideway 33 and horizontal line angle are 0 degree, obtain sawtooth wave.
The utility model 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 uses physical construction to replace hydraulic structure, to improve transmission accuracy, promotes testing efficiency, reduces production cost.
