摘要
混沌振动为不同于简谐振动的一种非线性振动 ,是由一定的振幅带和频率带复合而成。由此而产生土体的多个振动加速度值 ,迫使土颗粒克服内力而呈液化状态 ,从而为压实创造了条件。从两台振动参数相当的 10t级振动压路机 (振动主频率相同 ,振幅均值相近 )对比实验得知 ,混沌振动的压实度高于一般的简谐振动 。
Chaos vibration is a nonlinear vibration which is different from simple harmonic vibration It is combined by amplitude band and frequency band It causes multiple acceleration values to the soil The soil overcomes its internal force and becomes liquidization state So it creates good condition for compaction We use two kinds of 10t class vibratory rollers(Their frequencies are equal,and amplitudes are similar)to test From the result,we know the compactness of chaos vibration is higher than the one of simple harmonic vibration At the same time,its energy is higher too
