| 摘 要： | 建立了一类两自由度摩擦碰撞振动系统的力学模型,确定Poincare截面,通过数值仿真,分析了系统在简谐激振力作用下的周期碰撞振动特性,并讨论了传动带运动速度、传动带与质量块间的摩擦系数对系统周期碰撞振动特性的影响.研究结果表明系统的周期碰撞运动的形式呈现多样化,且在一定的系统参数下,传动带运行速度和摩擦系数的变化对系统的冲击速度影响不大,但对系统的动力学特性有较大的影响.

| Abstract: | A two-degree of freedom vibro-impact system with dry friction is established. The periodic impact vibration characteristics of the system under the harmonic excitation force are analyzed by numerical simu- lation, then the influence of the velocity of tile driving belt and the friction coefficient between the mass and driving belt on the periodic impact vibration characteristics of the system are discussed on the basis of de- termined Poincar6 section. The studies show that the forms of periodic impact motion are diversified, and under certain parameters of the system, the changes of the velocity of the driving belt and the friction coefficient have a little influence on impact velocity of the system, but have a great influence on the dynamic characteristics of the system. |
