The exciting force refers to the periodic simple harmonic vibration generated by the rotating unbalanced mass as the vibration source of the vibration system, which is called the exciting force. This unbalanced mass is a vibrating polariton. According to this principle, the vibrating table of the sliding table vibration forming machine is designed. The force that causes a vibrating body to vibrate. Its direction may change back and forth, such as hydraulic vibration, or change in 360° direction, such as eccentric mass rotation vibration. The exciting force of hydraulic vibration is determined by the thrust of the piston in the hydraulic cylinder, which is related to the area of the piston and the liquid pressure; the exciting force of the uniaxial eccentric block is equal to the centrifugal force generated when the eccentric block rotates, which is related to the mass, eccentricity and rotational speed of the eccentric block ; The excitation force of the biaxial eccentric block is equal to the vector sum of the centrifugal force of the two eccentric blocks. If the initial phase of the two eccentric blocks is symmetrical, the rotational speed is equal, and the direction of rotation is opposite, the centrifugal force will sometimes be superimposed and sometimes cancelled, forming a reciprocating directional vibration.
