Embodiment 1

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

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

[0024] According to the source of the vibrating object, the vibration medium damped in the fluid medium in the fluid medium is divided into side damping R. m1 Well-faced damping R m2 Two categories;

[0025] Among them, side damping R m1 Since the side of the object parallel to the vibration direction, the restriction of Skating R m2 The resistance from the object that is perpendicular to the vibration direction.

[0026] Side damping r of the vibration object m1 Well-faced damping R m2 The derivation process of the calculation formula:

[0027] 1, reference figure 1 , Set the separator of the vibrating body as a rectangular square, and set the length of the vibrating object to be a, the width is b, th...

Abstract

The invention discloses a medium damping calculation and analysis method for vibration of a mechanical vibration system in a fluid medium. The method comprises the steps of: dividing vibration damping borne by a vibration object in the fluid medium into side damping Rm1 and head-on damping Rm2; calculating side damping Rm1; calculating head-on damping Rm2. According to the medium damping calculation and analysis method for vibration of a mechanical vibration system in a fluid medium, the classification and the source of the vibration damping are determined by means of definition and connotation research of the vibration damping, and the mechanical vibration in the fluid medium is correctly and deeply known; the method for calculating and analyzing the damping is provided, a foundation is laid for deep research and numerical analysis of damping, vibration and resonance, the scientific principle is clear, the steps are simple and clear, and operability is high.

Description

Technical field [0001] The present invention relates to the field of fluid machinery and mechanical vibration technology, and more particularly to a medium damping calculation and analysis method of mechanical vibration system in fluid medium. Background technique [0002] Vibration is common in nature, daily life and industrial and agricultural production, refers to reciprocating movements made near the balance position. Resonance is a special state of vibration, which is a phenomenon that the system amplitude is significantly increased and the system amplitude is significantly increased when the system is equal or similar to the system induced frequency. [0003] Mechanical vibration is divided into damping vibration and no damping vibration, and the mechanical vibration encountered in normal life and working environment is more damping vibration. However, it is undeniable that the science and technology community is not well understood, the definition is unclear, and the class...
