0引言熨平板是摊铺机的工作单元,其功能是将摊铺宽度范围内的摊铺材料均匀压实,摊铺出致密平整的道路。熨平板压实系统通过对摊铺料的预压实,使摊铺层达到尽可能理想的压实效果,从而将后续压路机对摊铺层压实的影响降至最低~[1]。摊铺机熨平板脉冲梁(一种比摊铺机振捣器捣实频率大很多的装置,其功能是产生一个高频率的垂直方向上的往复运动)是一种特殊 0 Introduction Screed is the work unit of the paver. Its function is to compact the paving materials within the paving width evenly and to pave the way for compact and smooth construction. The screed compacting system achieves the ideal compaction effect of the paving layer by pre-compaction of the paving material, thus minimizing the impact of subsequent rollers on the paving compaction [1]. Paver screed pulsed beam (a device with a much larger frequency than the paver vibrator tamper, which functions to produce a high frequency reciprocating motion in the vertical direction) is a special
