一、振动理论的应用 振动压路机通过滚筒的振动加上滚筒静重这两个力的复合而得到压实效果。在滚筒里的旋转偏心块产生激振力,激振力是振子质量、频率和偏心距的函数。它们使滚筒振动,振动滚筒的频率和振幅反过来产生振波,并以动负荷及冲击力快速地作用于地面。每次荷载循环产生一个应力波,这些应力波的特性以及振动压路机压实的最后结果,在 First, the application of the theory of vibration Vibratory roller through the roller vibration plus roller static weight of these two forces and the compaction of the compaction effect. The rotating eccentric mass in the drum generates the exciting force, which is a function of the mass, the frequency and the eccentricity of the vibrator. They vibrate the drum, vibrate the drum’s frequency and amplitude and in turn generate vibrations and act quickly on the ground with dynamic loading and impact. Each load cycle produces a stress wave, the characteristics of these stress waves, and the final result of compaction of the vibratory roller, at
