摘要
为了给一种新型振动机的参数设计提供理论依据,将其抽象为双物理摆的力学、数学模型.借助Matlab软件对其振动系统发生的动力学特性进行仿真分析,得到了在给定参数a=0.01,b=0.0218,r=0.04,m1=2.16,m2=3.2,fv=0.1772,Jb=3.4798×10-3下的力学行为的五个混沌特征.
In order to provide theoretical basis for the parameter of design on a new type of vibration generator, this parameter of design is seen as a double-body pendulum and mathematical model. The dynamics characteristics of vibration system are made the simulation analysis with the aid of Matlab software. With the parameter a= 0.01, b= 0. 0218, r= 0.04, m1=2.16, m2=3.2, fv=0. 1772, Jb=3. 4798×10^-3, there are five chaos characters induced from the system.
