摘要
研究了两自由度含有滞迟干摩擦环节动力吸振器的简谐激励响应计算问题 ,提出了双线性滞迟阻尼力 Fourier级数展开技巧与一次谐波平衡法相结合的处理方法 ,并推导了相应的选代方程 ,给出了利用最优化理论中梯度算法迭代求解非线性频响方程组的过程。混过一个数例的分析 ,初步考察了滞迟干擦动力吸振的基本性能。
By using Fourier series expansion harmonic balancing technique, and the gradient iteration method in pptimum design theory, the response computation of a hysteretic vibration absorber system under harmonic excitation was discussed.And the nonlinear amplitude frequency equations were also derived. At the sametime, the nonlinear characteristics of a hysteretic vibration absorber system were obtained through numerical analysis.
