Low Frequency Characteristics of a Two-Degree-of-Freedom Vibration System with Complex Rigid Constraints. (September 2020) - Wang, Shijun
Abstract: The dynamic model of a two-degree-of-freedom impact vibration system with complex rigid constraints under the action of periodic excitation force is established. Through the multi-objective and multi-parameter numerical simulation, the types and distribution areas of the periodic impact motions of the system in the ( ω, δ )-parameter plane are obtained. The transition law of the fundamental impact motions of the system in the low frequency area is discussed, the generation mechanism of the tongue-shaped regions appearing in the transition process and the types of subharmonic motions in the tongue-shaped regions are analyzed.
