2025年1月8日 · Key Differences between FIV and AIV: Frequency: FIV is low-frequency, while AIV is high-frequency. Flow Type: FIV is associated with liquid flow, whereas AIV is associated with gas flow. Sound: AIV produces sound waves within the range of human hearing, while FIV produces less audible sound. Mitigation Strategies

声致振动acoustic vibration（AIV），指的是置于声场中的构件由于声波的激励而产生振动的现象。 构件的振动响应不仅与声波的强度、频率及入射方向有关，还取决于构件本身的性质，如固有频率、形状等。

Acoustic-induced vibration (AIV) and flow-induced vibration (FIV) are two common phenomena that can lead to vibration-induced fatigue failures in piping systems. Pipeline facility managers, operators, designers, and engineers are faced with identifying and mitigating the risks of …

Acoustic Induced Vibration (AIV) is generally applicable to lines in gas service. In a Gas System, high levels of high frequency acoustic energy can be generated by a pressure reducing device such as a Relief valve, Control valve or Orifice plate.

AIV is a global wholesale distributor of valves and actuators for the chemical, oilfield, petrochemical, pulp & paper, refining, power and water treatment industries. Established in 1991 as a resource for hard-to-find, exotic alloy and specialty valves, AIV has built a reputation as a premier master distributor in this arena.

2021年9月14日 · Two of the most common piping induced vibration studies we conduct at WKC are Acoustic Induced Vibration (AIV) and Flow Induced Vibration (FIV). Although both are classified as flow induced excitation mechanisms by the Energy Institute Guidelines, how the excitation is created, how the pipe responds to the vibration and the control measures ...

AIV stands for acoustic induced vibration and FIV stands for flow induced vibration. Following are the main differences between the two vibration types: Flow induced vibrations have low frequencies less than 100 Hz. Acoustic induced vibrations are high frequency acoustic waves with frequencies in the range of 500-2500 Hz.
