Embodiment 1

[0022] Embodiment 1 provides a medium damping calculation and analysis method for a mechanical vibration system vibrating in a fluid medium, wherein the vibration medium is a fluid, and the calculation and analysis method includes:

[0023] Step A: Determine the source and classification of vibration damping;

[0024] According to the force source of the vibrating object, the vibration medium damping of the vibrating object in the fluid medium is divided into side damping R m1 and oncoming damping R m2 two categories;

[0025] Among them, the side damping R m1 Derived from the resistance on the side of the object parallel to the vibration direction, the oncoming damping R m2 Derived from the head-on resistance of an object perpendicular to the direction of vibration.

[0026] Side damping R of a vibrating object m1 and oncoming damping R m2 The derivation process of the calculation formula:

[0027] 1. Reference figure 1 , the vibrating object is set as a cuboid insula...

Description

technical field [0001] The invention relates to the technical field of fluid machinery and mechanical vibration, in particular to a medium damping calculation and analysis method for the vibration of a mechanical vibration system in a fluid medium. Background technique [0002] Vibration is common in nature, daily life, and industrial and agricultural production, and refers to the reciprocating motion of an object near its equilibrium position. Resonance is a special state of vibration, which is a phenomenon in which the system amplitude increases significantly and reaches the maximum value when the excitation frequency of the system is equal to or close to the natural frequency of the system. [0003] Mechanical vibration is divided into damped vibration and undamped vibration. The mechanical vibration encountered in normal life and working environment is mostly damped vibration. However, it is undeniable that the scientific and technological community has insufficient und...
