摘　　要：在声波等外部激励的作用下,气泡会发生共振,表现出强烈的非线性,同时气泡与外部会发生强烈的能量交换并对系统的运行稳定性和安全性造成影响。该文综述了气泡的非线性振荡特性及其在外部声激励作用下的共振现象。单频激励时,根据外部声场频率与气泡自然频率的比值,可将共振分为主共振、超谐波共振和亚谐波共振:主共振频率响应曲线存在跳跃现象和迟滞现象;亚谐波共振的频率响应曲线由稳定、不稳定区间两部分组成;超谐波共振仅在一定的调谐参数范围内出现。当气泡振荡系统受到多个声激励共同作用时,气泡将出现组合共振、联合共振等非线性现象:组合共振又可分为和型组合共振以及差型组合共振,其共振特性受声激励总振幅的影响;联合共振频率响应曲线的不稳定区域随着声场振幅变宽。Under the influence of external excitations such as sound waves,the bubbles will resonate and exhibit strong nonlinearity.At the same time,the bubbles will undergo intense energy exchange with the outside world and affect the operating stability and safety of the system.In this paper,the nonlinear oscillation characteristics of bubbles and their resonance phenomena under external acoustic excitation are reviewed.When single-frequency excitation is employed,according to the ratio of the external sound field frequency to the natural frequency of the bubble,the resonance can be divided into three types:primary resonance,superharmonic resonance and subharmonic resonance.The primary resonance frequency response curve shows jumping and hysteresis phenomena.The frequency response curve of subharmonic resonance consists of two parts:stable region and unstable region.The superharmonic resonance only occurs within a certain range of tuning parameters.When the bubble oscillation system is subjected to the combined effects of multiple acoustic excitations,the bubbles will exhibit nonlinear phenomena such as combination resonance and simultaneous resonance.The combination resonance can be divided into additive combination resonance and subtractive combination resonance,and its resonance characteristics are affected by the total amplitude of acoustic excitation.The unstable region of the frequency response curve of simultaneous resonance could be enlarged by the amplitude of the acoustic field.
