Mechanical vibration refers to the regular reciprocating motion of an object or particle near its equilibrium position. The intensity of the vibration can be measured by the displacement, velocity or acceleration of the vibrating body. If the vibration exceeds the allowable range, the mechanical equipment will produce a large dynamic load and noise, thus affecting its performance and service life, serious will lead to the early failure of zero, components.

For example, the fracture of turbine blade caused by vibration can cause serious accidents. Because the modern mechanical structure is more and more complex, the movement speed is increasing day by day, the harm of vibration is more prominent. On the contrary, the mechanical equipment that USES vibration principle to work, should be able to produce anticipated vibration. In the field of mechanical engineering, in addition to solid vibration, there is fluid vibration, and solid and fluid coupling vibration. The surge of air compressor is a fluid vibration.

Only on the basis of the known dynamic model, external excitation and working conditions of mechanical equipment can the dynamic characteristics of mechanical equipment be analyzed and studied. Dynamic analysis includes: (1) calculation or measurement of the natural frequency of mechanical equipment of each order, modal mode, stiffness and damping and other natural characteristics. According to the inherent characteristics, the causes of vibration can be found to avoid resonance, and the basic data can be provided for further dynamic analysis. (2) calculation or measurement of mechanical equipment when the point of displacement, speed, acceleration, phase, spectrum and vibration of the dynamic response, dynamic response assessment of mechanical equipment to withstand the vibration and impact of the ability to find its weak links and waste links, to provide a basis for improving the design. The motion equation of the mechanical system expressed by modal parameters can also be established, which is called modal analysis. (3) analyze and calculate the dynamic stability of mechanical equipment, determine the instability of mechanical equipment, that is, the critical condition of self-excited vibration. Ensure that the mechanical equipment in full play of its performance under the condition of no self-excited vibration, and can work steadily.
