摘要
考虑环境阻尼因素的影响,研究了具有运动约束作用Kelvin-Voigt型输流曲管的混沌运动现象.数值仿真表明,输流曲管系统在某些参数取值时具有混沌运动的可能,管道材料的粘弹性系数和环境阻尼等因素对曲管的动力响应产生较大的影响.这些结论可为工程管道系统的铺设与设计提供参考.
Considering the environmental damping, this paper investigated the chaotic vibrations of a Kelvin-Voigt type curved pipe conveying fluid subjected to motion-limiting constraint. Numerical simulations indicate that the chaotic vibrations can be induced for certain parameter values of the curved pipe conveying fluid, and the environmental damping and viscoelastic coefficient greatly affect the dynamic responses of the curved pipe. The results provided a reference for tubing and design of pipe system in engineering applications.
