【摘要】：以Euler-Bernoulli懸臂梁作為研究對(duì)象,對(duì)主被動(dòng)混合壓電網(wǎng)絡(luò)(Active-Passive Hybrid Piezoelectric Network,APPN)進(jìn)行分析與優(yōu)化。利用Hamilton原理和Rayleigh-Ritz法建立集成式和分離式APPN懸臂梁結(jié)構(gòu)的動(dòng)力學(xué)模型,并對(duì)APPN中的電阻和電感進(jìn)行參數(shù)優(yōu)化。在此基礎(chǔ)上,利用速度反饋控制設(shè)計(jì)主動(dòng)控制器,分別對(duì)集成式和分離式APPN懸臂梁結(jié)構(gòu)的開環(huán)和閉環(huán)特性進(jìn)行數(shù)值仿真分析。仿真結(jié)果表明,兩種結(jié)構(gòu)形式的APPN均能夠有效地抑制結(jié)構(gòu)振動(dòng),集成式APPN在窄頻帶的振動(dòng)控制性能優(yōu)于純主動(dòng)控制,而分離式APPN則在更寬的頻帶具有比集成式APPN和純主動(dòng)控制更好的振動(dòng)控制性能。
[Abstract]:The Euler-Bernoulli cantilever beam is used as the research object to analyze and optimize the active passive Hybrid Piezoelectric network (APPN). The dynamic models of the integrated and separated APPN cantilever structures are established by using the Hamilton principle and the Rayleigh-Ritz method. The parameters of resistance and inductance in APPN are optimized. On the basis of this, the active controller is designed by using speed feedback control. The open-loop and closed-loop characteristics of the integrated and separated APPN cantilever structures are numerically simulated and analyzed respectively. The simulation results show that the two types of APPN can effectively suppress the structural vibration. The vibration control performance of integrated APPN is better than that of pure active control in narrow band, while the vibration control performance of separated APPN is better than that of integrated APPN and pure active control in wider frequency band.
