摘 要: | 采用多体系统动力学建模方法,建立了圆曲线路径构型双线摆式吸振器的非线性动力学模型,采用Runge—Kutta法和Newmark法进行了时域响应的直接求解,并以桨毂中心的力传递率作为衡量指标,讨论了设计参数,诸如吸振器离心质量块质量、调谐、阻尼对吸振性能的影响以及桨毂中心纵横向加速度阻抗对吸振性能的影响。

Abstract: | The nonlinear formulation of the hub mounted bifilar absorber was developed within the framework of muhibody dynamics. Then, Runge-Kutta and Newmark algorithm was used in time in- tegration of dynamic formulations mentioned above. The intrinsic parameters such as: dynamic mass, tuning, damping, which have vital influence on absorber efficiency were discussed. |
