A kind of four-bar Sine Pressure Generator, this device comprises: motor, driving lever, follower lever, stop, piston rod, piston cylinder, fixed support, traversing carriage.
Connection between this device each several part:
Motor is fixed on fixed support, the rotating shaft of motor is connected with driving lever, drive driving lever moves in a circle, follower lever is connected with driving lever, under the effect of stop, follower lever drives piston rod to move reciprocatingly in piston cylinder, piston cylinder is fixed on traversing carriage, the air sealing in piston cylinder is compressed sinusoidally, produce the pressure of sinusoidal variations, the change frequency of pressure is identical with electric machine frequency, carry out the frequency of sinusoidal pressure in regulating piston cylinder by changing motor speed, by regulating traversing carriage position in the horizontal direction to change the initial volume of confining gas in piston cylinder, thereby regulate the amplitude of sinusoidal pressure.
By the Ideal-Gas Equation:
PV＝nRT
