摘要
阐述了求解考虑主系统阻尼的动力减振器优化参数的一种数值方法;提出了基于主系统幅频响应曲线面积最小的参数修正方法。在不受共振峰值最小限制的前提下,按此修正方法针对不同的激振角频率对优化参数进行修正。修正后,虽然主系统的最大相对振幅略有增加,但动力减振器在特定频带内的减振效果得到了改善。
A numeric method of calculating optimal parameters of dynamic reducer considering the damping effect in the main system is expounded. The method of revising optimal parameters based on the critcrion of minimum area of the curve of main system's response is presented. On the premise of no limitation on the peak value of resonance, the method can be used to modify optimal parameters under different angular frequency of excitation. After revising, though there is probably some increase in the maximal relative value of amplitude of the main system, the effect of dynamic reducer is improved within certain designated frequency range.
