摘要:
振幅是振动压路机的一个主参数，但国标中名义振幅的概念是基于质点振动理论给出的，没有考虑振动轮振幅不均匀的问题，也没有考虑它在压实过程中的变化．通过分析与试验得到，振幅分为设计振幅、名义振幅与实际振幅3种，名义振幅与设计振幅比较接近，实际振幅要比名义振幅稍大；而且，振动轮的实际工作振幅是不均匀的，对此国标中没有指出，也没有给出相应的测试标准．因此，建议国标中的名义振幅值采用沿轮宽方向多点振幅测试结果的平均值，并增加振幅的不均匀度来衡量振幅的不均匀程度，使得单钢轮不均匀度< 5%，双钢轮的单轮不均匀度< 5 %，且前后轮之间的不均匀度< 5 %．
Abstract:
Amplitude is a main parameter of vibratory roller, but the nominal vibration amplitude concept is based on particle vibration
theory without consideration of uneven amplitude problem or amplitude variation during the compaction process. Through analysis
and trials, the amplitude is divided into 3 kinds: design amplitude, nominal amplitude and work amplitude. The nominal amplitude
is close to the design amplitude and the work amplitude is slightly larger than the nominal amplitude. Furthermore, the work
amplitude is uneven in practical work, which is not indicated and has no corresponding test standard in national standard, so we suggest
the average amplitude of several measuring points along the vibration drum width direction be used in national standard so as to
increase amplitude unevenness to measure the degree of uneven amplitude. The amplitude unevenness must be less than 5% for single
drum roller, and one wheel of double drum roller. And the unevenness between the front and rear wheels of double drum roller
should also be less than 5%.
