When carrying on the modal analysis, studies that the low step vibration gets up the leading role, prepares for the further dynamic analysis. 對齒輪進(jìn)行模態(tài)特性分析時(shí)，研究了齒輪的振動(dòng)是低階模態(tài)起主導作用，為齒輪進(jìn)一步的動(dòng)態(tài)分析做好準備。
The response velocity of transducer was measured by the laser Doppler vibrometer.The loading and unloading process were analyzed and modeled in three segments. 據此對超聲加卸載過(guò)程分段，進(jìn)行頻譜分析和非穩態(tài)特性建模，并研究了相關(guān)的試驗方法。
