振荡压路机名义荡幅的探讨

根据对振荡轮原地不滑转振荡时的理论和仿真分析，提出了振荡压路机名义荡幅是振荡轮原地不滑转振荡时荡幅的极限值，给出了名义荡幅的求解方法，从而得出了名义荡幅的表达式，发现振荡压路机原地不滑转振荡时振荡轮的荡幅是随频率比和阻尼比变化的。在公式推导的基础上结合具体工程算例指出，工作荡幅与名义荡幅是两个完全不同的概念。

Disscussion on Nominal Oscillatory Amplitude of Oscillatory Roller

According to theoretical analysis and simulation of the oscillatory drum under the stay condition, an assumption that the nominal oscillatory amplitude is the limit value of the stay oscillatory amplitude is put forward; the method that solves the nominal oscillatory amplitude is given; the expression of nominal oscillatory amplitude is obtained, and it is found out that the oscillatory amplitude varies with frequency ratio and damping ratio. A conclusion that working oscillatory amplitude and nominal oscillatory amplitude are two different concepts is drawn based on the formula derivation combined with calculation.
